- Programs 80 – 128 are sounds meant to played from a keyboard; some have sequences programmed, and some do not. Most respond in different ways to keyboard pressure and mod wheel.

- Sequencer Operation
- While the sequencer is running, if you hold the Shift button when you hit the Stop button, the sequence will continue running until finished (according to the length of Sequence 1), and will stop after playing step 1.
- A simple “tap tempo” feature is available. With the sequencer off, hold the Reset button, and then hold the Start/Stop button for a count of four; then lift up the Start/Stop button in time. The sequencer will start with the new tempo. Note – the actual speed will depend on the Clock Divide setting. The count will match if Clock Divide is set to 4n. If set to 8n, it will play twice as fast as your “tap”, and so forth.

- Filter Envelope
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
miON
Mono – Both channels mixed to the center – also useful
when only using one output
