It is also possible to enhance frequencies in a certain range with the resonance parameter (Q). It makes a sound more brilliant. Filter
Modulation The
frequency that is at the edge of the filter curve is called the cut
off frequency. By moving this frequency you can change the sound from
acid to dull. This moving can be done with a modulation curve so
that you can dynamic change the sound during the lifetime of a tone. The modulation can be done with an ADSR curve or better with a filter curve that starts at a certain level and move exponential to the end level, because a filter cut off frequency should never be zero like an ADSR. As a result the sound will shift from bright to dark or vice versa. A “Shift Effect” start bright and ends dull. It is often used for percussion instruments because natural higher overtones decrease faster than lower. “Sweep Effects” starts soft and ends bright. It is often used for synthesizer PADs. Modulation with a LFO results in a “Wah-Wah Effect”. |
