Env - Roland JX-03 User Manual

ENV (Envelope Generator)
This generates a control voltage (CV) envelope which controls the VCF and VCA, therefore, alters the tone color and
volume in each note by way of Attack, Decay, Sustain and Release knobs. It works with and is triggered by the
keyboard gate input which is generated by a key played on the keyboard, or a MIDI note arriving which then emulates
one. Attack is the timing of the envelopes beginning, Decay and Sustain are the behavior of the envelope while the
gate occurs, and Release is what happens in the voltage once the gate stops.
ATTACK
This determines the time required for the voltage to reach its maximum from the moment the key is pressed
down, or a MIDI note on message arrives.
DECAY
This determines the time required for the voltage to drop from maximum to the level set by Sustain.
SUSTAIN
This sets the sustain level to which the voltage falls at the end of the decay time.
RELEASE
This sets the time needed for the voltage to reach zero after a ket is released, or a MIDI not off message is
received.
NOTE - When all the ADSR are set to zero, the waveform will be an extremely short pulse wave, and only a short
"click" is heard.
