MONOTONE BASS SYNTHESIZER918
If you want to emulate the volume envelope of a note played on a piano for example, the Attack should be set to “0”,
the Decay parameter should be set to a medium value and the Sustain level should be set to “0”, so that the volume
gradually decreases down to silence, even if you keep holding the key down. Should you want the decay to drop to
some other value than zero, you raise the Sustain parameter.
S(ustain)
The Sustain parameter determines the level the envelope should rest at, after the Decay stage. If you set Sustain to
full level, the Decay setting is of no importance since the volume of the sound is never lowered.
If you want to emulate the volume envelope of an organ, you theoretically only really need to use the Sustain param-
eter set to full level, as a basic organ volume envelope instantly goes to the maximum level (Attack “0”) and stays
there (Decay “0”), until the key is released and the sound instantly stops (Release “0”).
But often a combination of Decay and Sustain is used to generate envelopes that rise up to max level, then gradually
decreases to finally land to rest on a level somewhere in-between zero and maximum level. Note that Sustain
represents a level, whereas the other envelope parameters represent times.
R(elease)
The Release parameter works just like the Decay parameter, except it determines the time it takes for the volume to
drop back to zero after you release the key.
Vel
D Turn up the Vel knob if you want the maximum level to be controlled from Keyboard Velocity.
The harder you play, the louder the maximum volume.
Chorus
This is a stereo Chorus effect, which can be used for generating a fatter and wider sound.
Amount
D Set the Dry/Wet amount of the chorus effect.
Set to 0% for a completely dry (unprocessed) signal.
Rate
D Set the rate/speed of the chorus modulation.
Spread
D Set the stereo width of the chorus effect.
Set to 0% for a if you want the signal to be in mono.
