Avalon keyboard CV and filter/amp envelope gating from
external analog gear.
[6]
CV & GATE OUT are 1/8" mono jacks that output sequencer
pitch CV and gate. The CV output is 1V/Oct and the range is 0V
to 5V. The gate output is a 0-12V V-trigger.
[7]
SWP OUT is a normalized copy of the accent sweep control
voltage that is derived on accented notes. The output is 0V to
5V max.
[8]
FILT CV accepts a CV input for controlling filter cutoff frequency.
The response is 1V/Oct. The useful range is 0-5V.
[9]
VCA OUT is the output signal from the VCA.
[10]
EXT IN is an audio input to the filter. It accepts a wide range of
signal levels as it has an internal preamp stage. When the
external input is used the sub oscillator is bypassed.
[11]

Extended range is -6dB @ 30Hz.
[17]
FILT B selects between the internal filter and a filter cartridge.
When the switch is pushed in (enabled) the filter cart is
selected. If FILT B is selected and there is no filter cartridge
inserted there will be no audio output from the synth.
