What do the voice names mean on Yamaha or Roland musical instruments?

 Name AvailabilityDoable on sampler programs? Description 
 "Regular"All  YesYamaha Basic patch. Nothing special about these, the samples can range from low quality mono patches that sound terrible, to high quality stereo samples. Most synth patches are regular, with the notable exceptions of S.Art! synths on Yamaha keyboards and SuperNATURAL(R) Synths on Roland keyboards. Also, some DX Electric Pianos are Cool!, Natural! or S.Art! in Yamaha keyboards.
PSR-S all
PSR-EW400+ (piano only) 
Tyros all
CSP all
Yes (true Live! sounds need different samples like the real thing)Yamaha Basic patch. Stereo sampled with real room reverb.
Examples: Acoustic instruments and ensemble instruments like strings, choir or brass.
PSR-S all
Tyros all
CSP all
 Yes (true Cool! sounds might need different samples like Live!)Yamaha Basic patch. Extra effects added to make electric instruments sound more realistic. Examples of the effects used include chorusing, velocity switching and EQ. In many cases, longer samples are also used compared to the "regular" patches.
Examples: Electric instruments. 
PSR-S all
Tyros all
CSP all
Yes (true Sweet! sounds need different samples like Live! and Cool!)Yamaha basic patch. Natural vibrato is in the samples of a Sweet! voice. Not to be confused with a "flauto dolce", translated to "sweet flute", another name for a recorder.
Examples: Solo acoustic instruments that have more potential to be expressive, like violin, flute, solo brass, harmonica or other orchestral instruments. Vibraphone and mandolin are also other instruments that can be Sweet! voices.
DGX-650+ (piano only)
YesYamaha basic patch. High quality samples are used. This is used for sounds with higher quality than their Live!, Sweet! or Cool! counterparts. Patches with a Live! counterpart must be stereo. Patches with a Sweet! counterpart should have vibrato. Patches with a Cool! counterpart should have effects.
Examples: Anything that Live!, Cool! or Sweet! covers can have a higher quality Natural! sound.
PSR-S all
Tyros all
CSP all
Yes (setBfree)

Impractical in Soundfonts
 (will be converted to S.Art!)

Partial (will be converted to
S.Art!Cool! or regular for samplers) 
Yamaha external emulation patch. In the original Yamaha keyboard that these are in, they provide an interface which is similar to the interface of a software organ emulator which is called setBfree. SetBfree runs as a plugin on the "J.A.C.K. Audio Connection Kit." The parameters can be changed in real time. In soundfonts this is only possible with some soundfont players. However, it is impractical. OrganFlutes! patches are only presets, and can therefore be emulated.
Examples: drawbar organs.
 VRM CVP-70x+
CSP all
 Partial (will be converted to Natural! for samplers)Yamaha external emulation patch. VRM stands for Virtual Resonance Modelling. This simulates the resonance of an acoustic piano, in the case of the Clavinovas, a Yamaha CFX or Boesendorfer Imperial 97-key piano (the Clavinova unfortunately does not have 97 keys on its keyboard). Modelling of resonance cannot be done on any sampler, however it is possible to use external resonance samples to simulate VRM patches. These will not be perfect, and this is the reason why they must be converted to Natural! when used with a sampler. If there is no release sample or other Natural! articulations, it will instead be Live! or Regular, depending on if the sample is mono or stereo.
Examples: pianos.    
MegaVoice! Tyros all
PSR-S all (except S500 and S550) 
Yamaha special patch. Mega voices use velocity layers in special ways (like "Jazz Scat" in Roland SC-8850, 006/053), but much differently. Each note can play far different notes in different velocity layers. Since this is the case, fixed velocity is used. 
Also, unlike Roland's Jazz Scat, the sample and velocity ranges are available on the data lists! Convenient! Megavoices are not suitable for keyboard playing, they are used for MIDI data.
Examples: instruments with different playing techniques, therefore guitars, basses, strings, brass.
 S.Art! or S.Articulation!Tyros2+
Electone all
Organs: Yes, modulators can be used to switch between fast and slow rotary modes, using both LFOs in the soundfont itself, or using samples for both high and low. Do not use bipolar mode for the modulators as there will be a click when switching from slow and fast mode, instead let the samples crossfade. Please note that the modulation wheel only works on some soundfont players.

Any patch using modulation wheel as articulation ONLY: Yes (samples can crossfade).

Any patch converted from Natural: Yes (if no undoable articulations are available in the original Natural patch)

Others: No (the articulations can be removed and patch converted into a 
Cool!, Live! or Sweet! patch)
Yamaha special patch. S.Art stands for Super Articulation 1 which is Yamaha's first version of the 2 Super Articulation versions that have been developed. In S.Art1 patches, you can expect round robin sample changing, bespoke modification of the poly mode to suit the instrument and in the case of organs, the usage of the modulation wheel to switch between fast and slow rotary speaker. Triggerable articulations are also included. Sometimes, this articulation is used when converting Natural! sounds from a Yamaha Clavinova to arranger keyboards which do not use the Natural! articulation, for example the Yamaha Genos "DX Production".
Examples: similar to MegaVoice!, however with the addition of pianos and organs. Synthesisers can occasionally be S.Art as well.
S.Art2! or S.Articulation2!Tyros3+
Electone all

 No (the articulations can be removed and patch converted into a Cool!, Live! or Sweet! patch)Yamaha special patch. S.Art2 is Super Articulation 2, the second of the Super Articulation versions developed. It is also called "Articulation Element Modelling(TM)". This is like Super Articulation 1, but it is more realistic. I believe that AEM(TM) has been patented, so it wouldn't be allowed anyway. Examples of improvements made versus S.Art1 are said to include improved vibrato control.
Examples: wind instruments, brass instruments, strings.
Drums or SFXAll Yes Yamaha basic percussion patch. These are just drum sounds (or percussion/sound effects if it is SFX instead) which would be in bank 128 of a soundfont. 
 Live!Drums or Live!SFXPSR-9000+
PSR-S all
Tyros all
Yes (true Live!Drums need different sounds to normal Drums)Yamaha basic percussion patch. These are stereo sampled drums with real room reverb, like standard Live! voices.   
 Revo!Drums or Revo!SFXGenos onlyYes (Hydrogen)
No (Soundfonts, but round robin can be removed and the patch converted to
Yamaha special percussion patch. These are like Live!Drums, but these include round robin samples. Soundfonts can not do round robin sampling, so it requires Hydrogen. This is very similar to the Standard Stereo kit in Roland SC-8850 and the Standard 3 kit in Roland SC-88Pro.
 Roland "Comp"SC-88Pro+  Yes (separate samples needed) Roland basic patch. Only applies to Clavi. Unknown what this means, does this mean compressor? 
Example: Comp Clavi
 Roland "Atk" (not zampona)SC-88Pro+ Yes (separate samples can be used) Roland basic patch.  Fast attack of a musical instrument. In the SC-8850, includes guitars, acoustic bass, electric bass, synth bass, solo strings, synth strings and clavi. In the SC-88Pro, only includes solo strings. "Atk" stands for Attack.
Examples: Attack Clavi 1, Attack Drive, Violin Attack.
 Roland "Zampona Atk"SC-88Pro+ Yes (seperate samples must be used)Roland basic patch. This patch is not a zampona with a faster attack, rather this is the sound that is produced by overblowing a zampona.
Example: Zampona Attack.
 "Trem." prefixAll  Yes (separate samples must be used in certain conditions)Roland basic patch. Instrument is played repeatedly or volume is affected by LFO. Featured in General MIDI, in patch 45, as Tremolo Strings. Trem stands for Tremolo.
Examples: Tremolo Organ, Tremolo Strings, Nay Tremolo.
 "Velo" prefixAll GS  Yes (separate samples can be used) Roland basic patch. This shows that the instrument is an expressive instrument that has velocity switches. Can also be a synthesiser.
Examples: Strings, Synth brass, Synth lead
Name Examples: Velocity Strings, Velocity Brass 
 Patch sfzSC-88Pro+ Yes (separate samples can be used)Roland basic patch. These patches are played in a sforzando method. Sfz stands for Sforzando. The patch called Synth Brass sfz was originally "Synth Brass 4".
Example: (Synth) Brass
Name examples: Brass sfz, Synth Brass sfz
 Patch w/KSPAll GS devices (w)
All XG devices (KSP)

 YesRoland/Yamaha basic patch. These use a technique to spatialise the sound, so low notes come from the left and high notes come from the right. "W" stands for wide and "KSP" stands for Key Scale Panning.
Example names of these patches: "Piano 2w" or "Electric Piano 2 KSP"
Examples: pianos, electric pianos, tuned percussion.
 Patch dAll GS devices
 YesRoland basic patch. This is a darker and more mellow sound for a piano. Name in XG is "Mellow Grand Piano", considered a normal "regular" patch. "D" stands for dark.
Only used in "Piano 1d". 
Examples: pianos.
 Patch oAll GS devices
Yes (requires different samples)Roland basic patch. Open patch, not sure what this is supposed to mean, however with the exception of the organ sound, these have key release sounds.
Name examples: "Organ o", "Nylon Guitar o"
Examples: Organs, guitars. 
 Patch : (colon)SC-88Pro+ Other samplers: Partially (Tx16wx can only do Mono portamento). No open source sampler program can do Poly portamento.
Soundfonts: No.
Roland basic patch. Built in portamento in the sample without need for CC68. Same samples as non-legato versions of the instrument. Basically an earlier version of the corresponding "Super Articulation" articulation, which does not use separate samples.
Name examples: "Strings:", "Baritone Sax:", "Flute 2:"
Examples: Instruments that can change pitch during playback of a note.
 Patch v/Velocity CrossfadeAll GS devices (v)
All XG devices (Velocity Crossfade)
 Yes.Roland basic patch. Velocity switching electric piano patches.
Name examples: "Electric Piano 1v", "Electric Piano 2v"
Examples: Electric pianos.
 "St." Prefix SC-88+Yes. Different samples may be needed for simulation, or mono samples can sometimes be converted with faux stereo.Roland basic patch. Stereo patches. Similar to Live! (this is why this entry is blue, like Live!) patches, but without the real reverb.
Name examples: "St. FM EP", "St. Strings", "St. Tenor Sax" 
Examples: same as Live! patches.
 "L/R" suffix Roland SC-8850 Yes. Stereo samples are needed. Roland basic patch. Means the same as "St." except for drums. "L/R" stands for Left/Right. Usually in strix documentation, "Stereo" is used instead of "L/R" (For example: "Standard L/R" is referred to as "Standard Stereo". Some left and right samples are decoupled from each other in the extended drum map.
 "Mt" suffixRoland SC-8850Yes. Different samples are needed, or they can be resynthesised from normal samples using decay. Roland basic patch. This is usually seen in percussion instruments and this means a muted instrument. These muted instruments have shorter volume envelope hold, decay and release.
Name examples: "Kopyak Mt".
Examples: Tuned percussion, especially ethnic percussion.
 "Side" suffixRoland SC-8850 Yes. Different samples are needed. Roland basic patch. Only applies to kelontuk, means a drum hit on the side rather on the drum. Kelontuk is a copyright trap!
 "Op" suffixRoland SC-8850 Yes.Roland basic patch. The opposite of "Mt" instruments, open instruments are not muted.
Name examples: "Kopyak Op".
Examples: Tuned percussion 
 "Nm" suffixRoland SC-8850 Yes. Roland basic patch. This means normal in uillean pipe and tin whistle. These patches are usually velocity switch, with "Nm" mode for normal velocity and "Or" mode, which is explained below, for high velocity.
Name examples: "Uillean Pipe Nm"
Examples: Uillean pipe and tin whistle
 "Or" suffixRoland SC-8850  Yes. Different samples are needed, or it can be resynthesised from the sample used for "Nm" patches. Roland basic patch. This mode is usually triggered on high velocity notes. "Or" means "orchestral", which doesn't really make much sense, as this is just the same sample as the "Nm" patch, but with different modulator envelope decay, hold and release, as well as the modulator envelope pitch which is measured in cents. Like "Nm", this is only seen in uillean pipe and tin whistle.
Name examples: "Tin Whistle Or"
Examples: Same as "Nm" patches.
 "Basic" suffixRoland SC-8850 Yes. Different samples or LPF can be used to create this. Roland basic patch. This is only for the B.Harp series of patches in 8850. "B.Harp" is believed to mean "Blues Harp", but the basic mode has a lowpass filter. (12dB is believed as the depth by Elf)
Name example: "B.Harp Basic"
Examples: Blues harp
 "Suppl" suffixRoland SC-8850 Yes. In soundfont, different samples must be used, either with different samples altogether or HPF. Roland basic patch. The B.Harp specific version of the high pass filter.  Suppl probably means supple. (The HPF depth is believed to be 12dB by Elf).
Name example: "B.Harp Suppl"
Examples: Blues harp
 "Exp." suffixRoland SC-88Pro+ Yes. Different samples or velocity crossfade can be used. Roland basic patch. Extremely similar to Sweet! patches, so the colour used in this entry is pink. These include automatic vibrato in the sample, and possibly velocity switching as well. "Exp." probably is short for "Expressive".
Name example: "Flute Exp."
Examples: Anything that can be a Sweet! patch, with the exception of vibraphone and mandolin.
"Travelso"Roland SC-88Pro+ Yes.Roland basic patch. "Travelso" has finally been decoded as meaning the same as "Traverso", or the baroque flute. Only samples available are Philharmonia Orchestra samples, which are restricted (CC-BY-SA with the Philharmonia restriction, so not CC-BY-SA!) Since Philharmonia Orchestra samples are unavailable from the original source, they can no longer be used at all. If free samples (free as in freedom, and compatible with GPL V3) are found, please send an email to dsoundfont123@gmail.com.
Only used in "Flute Travelso".
Examples: Flute.
 "Code"Roland SC-8850 Yes. Roland basic patch. In voice oohs, these represent a chord in the name.
Name examples: "Oohs Code Major 7th"
Examples: Voice oohs
 "TC" prefixRoland SC-88Pro+ Yes. Roland basic patch. Guitar patches sampled from a famous "Fender Telecaster" guitar. Examples of such samples are available on the Freepats website here. (These are GPLV3 with exception)
Name examples: "TC Muted Guitar"
Examples: guitars
 "LP" prefixRoland SC-88Pro+ Yes. Roland basic patch. Guitar patches sampled from a famous "Gibson Les Paul" guitar. Examples of such samples are available on Flamestudios, but these samples are GPLV3 without exception! The exception provided on the soundfont appears to be compatible with the Freepats exception as both allow use in non-GPL compositions. Alternatively, Bernhard Trummer's Gibson Les Paul samples can be used, these are CC-BY-SA 4.0 (Compatible with GPL V3, unlike CC-BY-SA 3.0!).
Name examples: "LP Overdriven Guitar"
Examples: guitars
 "JC" prefix Roland SC-88Pro+Yes. Roland basic patch. Guitar patches amplified with a famous "Jazz Chorus" guitar amplifier from Roland. These can be achieved with the Darlings.gx effect file in Guitarix. Guitarix can unfortunately, only be run in Linux. Alternatively, LMMS and the Calf Multi Chorus effect (LADSPA plugin) can be used for Windows systems.
Name examples: "JC Chorus Guitar"
Examples: guitars 
 "SuperNatural (r)"New Roland Pianos: No.
Others: Potentially
If not doable, can be converted to either 
Natural!"SemiNATURAL" or "PCM", the latter two terms used by Elf of Happy and Love. "Expressive!" will be the term in Mystical!, the SNC compatible version of Enchant!.
Roland special patch. "SuperNATURAL(r)" Pianos are partially physically modelled, similarly to VRM! pianos in Yamaha Clavinova. "Supernatural(r) Synths" are use virtual analog technology, probably Roland analog (digital in the case of the d-50) circuit behaviour. "Supernatural(r) Drums" are like Revo! drums or the Standard 3 or Standard Stereo kit on SC-88Pro and SC-8850. It is unknown what other SuperNatural(r) patches have, but it is probably similar to Yamaha's S.Art1/2 and Natural! sounds. Supernatural sounds must be converted to Expressive! or SemiNatural!
 V-PianoNew Roland No, must be converted to "SemiNatural!"
Roland special patch. This is entirely physical modelling, unlike the lower end Supernatural(R) technology. This is for Roland digital pianos and stage pianos (Like the RD2000)
 V-DrumsNew Roland No, must be converted to "SemiNatural!"  Roland special patch. This is entirely physical modelling, unlike the lower end Supernatural(R) technology. This is specific to Roland digital drum kits.
 "JP" prefixSC-88Pro+ Yes (different samples can be used) Roland basic patch. Synthesised with Roland's Jupiter series synthesiser. Can be followed by a number. For example JP-4 means Jupiter 4 and JP-8 means Jupiter-8. SC-8850 adds JP8000, a virtual analog synth by Roland, with the now infamous Super Saw and other waveforms like TWM (007/080) and Feedback Oscillator (026/084). The JP Super Saw can be emulated with Super 7 (unfortunately non free). Emulated by Bristol Audio (Linux only).
Name examples: JP-8 Clavi 1, JP Strings, JP Super Saw.
 "JX-8P" prefixRoland SC-8850  Yes (different samples can be used)Roland basic patch. These patches are synthesised with the JX-8P synthesiser by Roland. Emulated by the PG-8X synth (unfortunately non free and also closed source)
Name examples: JX-8P Organ, JX-8P Voice.
 "D-50" prefixSC-88Pro+ Yes (different samples must be used)Roland basic patch. These patches are synthesised with the D-50 (or D-05) linear arithmetic synthesiser by Roland. D-50 sounds are created with a sample attack layered with analog style subtractive synthesis. To resynthesise a "D-50" patch, custom attack sounds must be used with saw and square waves as well. D-05 is a simulation of the D-50.
Examples: D-50 Organ, D-50 Retour.
 "LA" prefixSC-88Pro+Yes (different samples must be used)Roland basic patch. LA stands for Linear Arithmetic. Patches with this prefix can be considered like sounds that have "D-50" as their prefix.
Examples: LA Sawtooth, LA Brass Lead (SC-8850)
Linear! Enchant!, Mystical! Yes (different samples may be used) Strix patch. These are equivalent to the above two articulations. Like D-50 and LA patches, these patches use the linear arithmetic method of synthesis. In Enchant, D-50 and LA patches are replaced by Linear! patches. 
 Linesynth! Stardream Studios SF Yes (different samples may be used) Elf patch. These are equivalent to the above two articulations. Like D-50 and LA patches, these patches use the linear arithmetic method of synthesis. In Starlight Dream, D-50 and LA patches are replaced by Linesynth! patches. This is equivalent to Linear! in Enchant.
 "Farf" prefixSC-88Pro+ Yes (different samples must be used)Roland basic patch. Farf stands for Farfisa. Only applies to the organ, this simulates a Farfisa electronic organ. There is also a Farfisa Grand Piano, but it is not an organ.
Example: Farf Organ. 
 "JUNO" prefixSC-88Pro+ Yes (different samples may be used)Roland basic patch.  These are synthesised with Roland's Juno series synthesisers. Juno Brass was called "Poly Brass" (the current XG name) before being renamed to Juno Brass in SC-88Pro. Emulated by Bristol Audio (Linux only) and Juno-6 VST.
Examples: JUNO Strings, JUNO Brass, JUNO Bell
 "Hybrid" prefixSC-88Pro+ Yes Roland basic patch. Real instruments mixed with synthesised instruments.
Examples: Hybrid Organ, Hybrid Brass, Hybrid Strings
 "VS" prefixSC-88Pro+ Yes Roland basic patch. Unknown, maybe "Prophet VS" (Sequential Circuits). Exclusive to organ.
Example: VS Organ. 
 "FM" prefixSC-88+ YesRoland basic patch. Synthesised with FM (frequency modulation) synthesis. An example of a famous FM synth is the Yamaha DX-7, used for the famous 80's FM Electric Piano sound.
Examples: Stereo FM EP, FM Organ, FM Slap Bass.
 "CS" prefixSC-88Pro+  YesRoland basic patch. Sampled from Yamaha CS-series (probably CS-80). Emulatable with Arminator 2 (license unknown, assumed to be proprietary).
Examples: CS Bass, CS Saw Lead. 
 "P5" prefixSC-88Pro+ Yes Roland basic patch. Sampled from Sequential Circuits Prophet 5. Emulated by Bristol Audio (Linux only).
Examples: P5 Bass, P5 Sync Lead. 
 "JPMG" prefixSC-88Pro+ Yes Roland basic patch. "Jupiter Moog"? Is this supposed to mean an emulation of a Moog Synth done with a Roland Jupiter Synth? Unknown. Only for synth bass.
Example: JPMG Bass.
 "MG" prefixSC-88Pro+Yes Roland basic patch. Sampled from a Moog synth (probably the MiniMoog). Can be emulated with Freemoog (Freeware, but not open source, therefore NOT free software.)
Examples: MG Bass, MG Unison, MG Resonant Pulse.
 "303" prefixSC-88Pro+ Yes Roland basic patch. Sampled from a Roland TB-303, famous for its use in "Acid" music. Emulated by LB-302 on LMMS.
Examples: 303 Square Distorted Bass, 303 Reverse Square.
 "OB" prefixSC-88+ Yes Roland basic patch. Sampled from Oberheim synthesisers.
Examples: OB Strings, OB Brass. 
 "SH-5" prefixSC-88Pro+ YesRoland basic patch. Sampled from Roland's SH-5 synth.
Examples: SH-5 Brass, SH-5 Bass Lead. 
 "MKS" prefixSC-88Pro+ Yes Roland basic patch. Sampled from Roland's MKS series. Only for brass.
Example: MKS Brass
 "LM" prefixSC-88+ Yes Roland basic patch. Unknown. Synthesised. If you know what LM means, please send an email to dsoundfont123@gmail.com.
Examples: LM Square, LM has come.
 "KG" prefixSC-88Pro+ Yes Roland basic patch. Maybe abbreviation for "Korg". Only for synth leads.
Example: KG Lead
 "TB" prefixSC-88Pro+ Yes Roland basic patch. "TB" means "TB-303", so means the same as a "303" patch. Only for synth leads. Emulated by LB-302 on LMMS.
Example: TB Lead 
 "GR" prefixSC-88+ YesRoland basic patch. Sampled from Roland GR-300 synth.
Example: Feline GR, Mellow GR Lead.
 "2600" prefixSC-88Pro+Yes Roland basic patch. Sampled from Arp 2600 synthesiser. Can be emulated with "Arppe2600va" (unknown license)
Examples: 2600 sine, 2600 sub oscillator.
 "LFO" prefixSC-88Pro+ Yes (separate samples are needed for non-sine LFO for use with soundfont)Roland basic patch. Synth patches with LFO (Low Frequency Oscillator). May or may not be sine wave LFO.
Examples: LFO Rave, LFO Techno, LFO Horror.
 "Random" series patchesSC-88Pro+ Yes (separate samples are needed)Roland basic patch. Has a sample and hold component (volume or pitch). Use "Surge" to recreate these patches.
Examples: Random Strings, Random Flanger Chord. 
 "Digi" prefixSC-88Pro+ Yes (separate samples can be used)Roland basic patch. Sampled from a digital synth. Digi stands for Digital.
Example: Digital Church Organ. 
"Dly" prefixSC-88Pro+ 
Roland Studio Canvas series
Yes (seperate samples can be used) Roland basic patch. Includes delay effect. Only for bass sound in SC-88Pro and SC-8850. Also delay for two orchestra hits, whistle and ocarina in Studio Canvas.
Example: Dly Bass 
 "DX" prefixYamaha Yes (seperate samples can be used) Yamaha basic patch. Sampled from Yamaha DX-7, so means the same as "FM". Normally refers to synthesised electric pianos made with the DX-7. Emulatable with Dexed (GPL). Can be used in conjunction with other articulations.
Cool! Sweet DX
 "PM" prefixSC-88Pro+ Partial Roland basic patch. Like legato enabled patches, PM stands for "PortaMento". Only for synth lead. PM Lead without portamento can be recreated in soundfonts, but the portamento effect can not. Like "Portatone" on Yamaha PSR-series.
Example: PM Lead 
 "VP" or "VP-330" prefix SC-88Pro+ Yes (separate samples) Roland basic patch. Sampled from Roland's famous VP-330 vocoder. Choir only.
Example: VP330 Choir.
 "MW" suffix Yamaha PSR-S910+
Yamaha PSR-S750+
Yamaha PSR-S670+
Yamaha PSR-SX All
Yamaha Genos All
Yamaha Tyros 3, 4 and 5
 Yes (separate samples)

Sometimes, it may not be possible to recreate MW tones perfectly.
 Yamaha basic patch. Designates a patch where the modulation wheel crossfades between two different sounds, or two different variations of a sound. For example, the modulation wheel can control the synthesiser parameters, like a low pass filter, or the modulation wheel can switch to completely different samples.
 "JS" suffix Yamaha PSR-SX All
Yamaha Genos All
 Yes (separate samples)

Sometimes, it may not be possible to recreate JS tones perfectly.
 Yamaha basic patch. Similar to the "MW" suffix, however the newer Yamaha keyboards have a joystick instead of the separate pitch bend and modulation wheels of the older keyboards.
 "SW" suffix (arranger version)Yamaha PSR-SX All  No (Soundfont).
Yes (SFZ)
 Designates round robin sampling. This is not doable in the soundfont standard (1994 !), therefore the patches must be converted to a megavoice. Used with the S.Art1! articulation.
 "SW" suffix (Clavinova version) Yamaha Clavinova CVP-800 series and later Sometimes (in soundfont).
Yes (SFZ)

Sometimes, it may not be possible to recreate these tones perfectly.
 Either means the same as "SW" on Yamaha arranger keyboards, or it replaces "MW" or "JS" because Clavinova keyboards do not have a modulation wheel or a joystick. If the corresponding tone on the Yamaha arranger keyboard is "MW" or "JS", it is doable in the soundfont standard, otherwise it's a round robin tone, which can not be done in the soundfont standard.
 Expressive!Mystical!Yes Strix special patch. Converted from Supernatural(r) patch on Roland device. 
Coming SOON...
 SemiNATURALSuper Natural ClassicYes Elf special patch. Converted from Supernatural(r) patch on Roland device.
Coming SOON... 
 Synthesiser! Stardream Studios SF, Enchant!, Mystical!Yes Denotes a synthesised sound. Acoustic instruments which have been recreated by synthesisers are denoted as "Resynth!" instead.
 Resynth! Stardream Studios SF, Enchant!, Mystical!Yes Denotes an acoustic instrument sound which has been recreated using a synthesiser. In Stardream Studios Soundfonts, these patches are prefixed with a "plus" symbol. 
 Revintage! Stardream Studios SF, Enchant!, Mystical! Yes Alternative name for "Resynth!" voices. Elf's standalone project with resynthesised voices is called "Revintage World".
 Dream!StarDream Studios soundfont, Enchant!Yes Elf special patch. An original patch by Elf. Stronger vibrato and longer release times with synthesisers. 
 Dream!2StarDream Studios soundfont, Enchant!YesElf special patch. An original patch by Elf. High quality ("natural") acoustic instruments mixed with Dream! layers.
 Angelic!StarDream Studios soundfont, Enchant!Yes Elf special patch. Reverb and decay effects are added to Dream! patches to create Angelic! sounds. 
 Angelic!2StarDream Studios soundfont, Enchant!Yes Elf special patch. Effects which are used in Cool! voices have been added to Angelic!1 voices.
Supervoice!Starlight DreamYes Elf special patch. Megavoice-like patches in soundfonts. Coming soon. 
Mystic! Enchant!Yes Strix special patch. Megavoice-like patches for Enchant!.
Coming soon.
 Atmosphere! (Atmos!) Stardream Studios SF, Enchant! and Mystical! Yes (separate samples may be required) Elf and Strix special patch. Synthesiser and acoustic tones with reverb and other DSP effects. Also includes longer release times, to create an atmospheric sound.
 Atmosphere!2 (Atmos!2)
 Stardream Studios SF, Enchant! and Mystical! Yes (separate samples may be required) Elf and Strix special patch. Synthesiser and acoustic tones with reverb and more DSP effects compared to Atmosphere!1 patches. Examples of DSP effects used include echo (delay), phaser and chorus. Even longer release times, to create an even more atmospheric sound.
 Atmosphere!3 (S.Atmos!) Enchant! and Mystical! Yes (separate samples may be required) Strix special patch. Synthesiser and acoustic tones with even more reverb and more DSP effects compared to Atmosphere!2 patches. Examples of DSP effects include all of the Atmosphere!2 DSP effects, and flanger effects, with high amounts of phaser and flanger feedback. Layering is also used. Release times are even longer compared to Atmosphere!2 patches, to create a sound which is extremely atmospheric. 
Atmosphere!4 (H.Atmos!) Enchant! and Mystical!  Yes (separate samples may be required) Strix special patch. Synthesiser and acoustic tones with even more reverb compared to Atmosphere!3 patches. These patches have many layers. Release times are even longer compared to Atmosphere!3 patches, to create a sound which is the most atmospheric of all the Atmosphere! patches. 
"1. S.Art!, S.Art2! and MegaVoices are not compatible with other instrument models. For this reason, any Song or Style you've created on this instrument using these Voices will not sound properly when played back on the instruments which do not have these types of Voices.
2. S.Art!, S.Art2! and MegaVoices sound differently depending on keyboard range, velocity, touch, etc."
These two extracts are extracted from a Yamaha keyboard manual. 
Yamaha special patches therefore can not be done, and must be converted to basic patches, like Live!, Cool!, Sweet! or Natural!. This also applies to Roland-esque "SuperNATURAL" patches.

Genos and PSR-SX series are the current keyboards by Yamaha. The Tyros series and PSR-S series are discontinued.

Soundfont 3 (proposed by Davy, the creator of Polyphone) will make many of these undoable patches doable. It will also remove the remapping required.

The Yamaha map and Roland GS support are mutually exclusive. Usage of the "Piano 1W" tone in GS on a Yamaha keyboard will cause a MegaVoice nylon guitar to playback instead, for example. This is almost certainly not the behaviour that the user who sequenced the MIDI file intended! Even though this is the case, the Yamaha keyboard manuals still show the Roland GS logo. Therefore, "Starlight Dream for Soundfont 3.0" would have to drop Roland GS and SC-8850 support!
