Highpass Filter
Highpass: 3 5 S o0…99, i0…99 Sets the cutoff frequency of the four-pole
highpass filter. If set to o00 to o99, the filter is placed after the analog lowpass filter
and VCA, before the Delay. If set to i00 to i99, the highpass filter is inserted before
the analog lowpass filter, and only affects external input. Refer to the Signal Flow
diagram on page 13. There are two separate highpass filters, one for each channel,
that are controlled in tandem.
Remember that any of the modulation sources can be routed to the Highpass Filter;
for example Envelope 3 can be dedicated to the Highpass.
Amplifier (VCA)
VCA Level: 4 1 0…100 Sets a base level for the VCA (Voltage controlled
Amplifier). This allows the VCA to be essentially bypassed, which may be necessary
for processing external audio signals, or for Programs that drone.
Note – if VCA Level is on full, then the Envelope Amount will have no effect.
Env Amt: 4 2 0…100 Amount of VCA envelope to the VCA level.
Attack: 4 3 0…110 Attack time of the VCA ADSR envelope generator
Decay: 4 4 0…110 Decay time
Sustain: 4 5 0…100 Sustain Level
Release: 4 6 0…110 Release time
Velocity: 4 2 S 0…100 Amount of MIDI velocity controlling the level of the
VCA envelope.
Output Pan: 4 7 see table pan settings as below. This affects the feedback; it
allows signal from one channel to feedback into the other, for example.
Display Output Pan Selection
St1 Stereo 1 – Left channel panned fully left, Right fully to the
right
St2 Stereo 2 – Left channel panned mostly left, Right mostly to
the right
St3 Stereo 3 – Left channel panned somewhat left, Right
somewhat to the right
m i ON Mono – Both channels mixed to the center – also useful
when only using one output
