EG2 ASR
EG2 is just the same as EG1. EG2 is generally assigned for use with modulating
VCO2 and the VCA.
ATTACK
Controls the Attack time. This is the rate at which the envelope signal will take to reach
full level when the MIDI note/key pressed.
DECAY
Controls the Decay or the Release time - the time it take the envelope signal to return
to zero when the key is released.
SUSTAIN
Controls the level the envelope will hold at when a key is pressed and the attack
cycle has completed.
VCA
The Voltage Controlled Amplifier (VCA) is the circuit
that is used to change the output volume. Normally an
envelope signal would be used to do this, so the sound
starts loud then gradually fades away. The filter audio
output is hard-wired to the VCA signal input.
MODE rotary switch
The VCA can be controlled in 4 modes;
EG2
When EG2 is selected, the envelope signal of EG2 is used to modulate the VCA level.
Use it if you require the VCA level to change over time. (Normal use).
MIDI/EG
When this is selected, EG2 is again used as the modulation source, but the overall
