Envelopes 
Mopho x4 has three 5-stage (Delay + ADSR) envelope generators per voice. 
Two are dedicated—one to the filter and the other to the amplifier—and the 
third is assignable to any modulation destination. 
Envelope Select—Selects the envelope to edit. When all three are lighted, the 
other envelope parameters control all three envelopes simultaneously. 
Amount: -127...127—Sets the amount of modulation from the envelope to the 
destination: filter, amplifier, or the selected destination for envelope 3. The 
modulation amount can be positive or negative, allowing for inverted envelope 
control. (For the VCA, the range is 0-127, since you can't have a negative gain 
on a VCA!) 
Delay: 0...127—Sets a delay between the time the envelope is gated on and 
when the Attack portion actually begins 
Attack: 0...127—Sets the attack time of the selected envelope(s). 
Decay: 0...127—Sets the decay time of the selected envelope(s). 
Sustain: 0...127—Sets the sustain time of the selected envelope(s). 
Release: 0...127—Sets the release time of the selected envelope(s). 
Velocity: 0...127—Sets the amount of key velocity used to modulate the 
envelope amount. 
Other Envelope Parameters 
There are two additional parameters for envelope 3 in the Miscellaneous 
Parameters section. 
Envelope 3 Destination—Sets the destination modulated by envelope 3. See 
Modulation Destinations on page 33 for a list of possible destinations. 
Envelope 3 Repeat: Off, On—When on, causes the delay, attack, decay, and 
sustain portions of Envelope 3 to loop for as long as the envelope is gated on. 
With repeat on, envelope 3 can even be used as a sort of complex LFO.
