RELEASE
Value Range: 00-15
Adjusts the length of time for the envelope to go from sustain level
to zero. If the key is released before the attack or decay periods have
elapsed, release controls the time taken for the envelope to drop to
zero from whatever its level when the key was released. If the attack
and decay periods have elapsed and sustain is set to 0, then the
release value is irrelevant, because the level is already minimum.
If filter release produces no effect, check that AMPLIFIER RELEASE
is set to approximately the same value.
KEYBOARD TRACK
Value Range: 00-02
00= Off
01= Half
02s Full
When Full, the KEYBOARD control voltage (CV) is applied to the
filter's cutoff frequency just as it is normally applied to the
oscillator. With the filter thus "tracking" the keyboard, cutoff
frequency is maintained at a constant point relative to the notes
being played. This results in a consistency of timbre over.the whole
keyboard range. When KEYBOARD is off, notes played higher on the
keyboard will have have a duller timbre. Obviously, the 1/2 value
selects the midrange between these two effects.
If FILTER RESONANCE is set for self-oscillation, setting
KEYBOARD on Full will allow the filter to be played from the
keyboard. However, since the filters in resonance are not precisely
tuned, there will be considerable error from the normal keyboard
scale. (Unless a complex effect is desired, ENVELOPE AMOUNT will
in this case normally be set to 0, to maintain a steady frequency from
voice to voice).
If the KEYBOARD parameter is toggled while holding keys down, the
effect will not be heard until the key is restruck.
AMPLIFIER
VOICE VOLUME
Value Range: 00-15
15= maximum signal-to-noise ratio
Programmable voice volume is a convenient way to balance the
loudness of programs so you aren't always fiddling with the Volume
knobs. Use it after the program is basically recorded.
The remaining amplifier controls are the envelope generator attack,
decay, sustain, and release parameters, which shape the envelope

applied to the VCA. These are identical to the corresponding filter
envelope parameters.
Unless the sustain parameter is turned up slightly, nothing will be
heard after the attack and decay periods have elapsed.
