- 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.

Program Parameters
There are eight rows of Program parameters. In addition, holding the S
HIFT button
gives access to an additional 64 parameters. The S
HIFT button operates two different
ways. While held, it always selects the alternate parameter (in yellow). The selected
row LED blinks to indicate that S
HIFT is selected. Alternatively, you can hit the SHIFT
button twice quickly, and now the matrix will be in shift mode – the row LED will blink,
and the alternate parameter is selected, but you do not have to hold the button down.
This is handy when tweaking while playing a keyboard with your other hand. Hit S
HIFT
once more and it returns to normal.
Note - sometimes the shifted parameter is related to the unshifted parameter
above it, but other times they are unrelated. The panel artwork shows the
grouping to make it more obvious.
To select a row to edit, simply hit the desired row button, and you can turn any of the
eight knobs to change a parameter in that row.
Note - you first select a knob and turn it one click, it selects and displays the
parameter but does not change the programmed parameter value. Any further
turning will then modify the value up or down. This makes it easy to check the
value of a parameter without changing it.
The following parameter details are grouped by function, with row and column as
indicated in the boxes: 5 2. Would be Row 5 Column 2 (the Grunge parameter, in
this case). An S denotes the SHIFT button is held down to access the parameter.
Oscillator 1
Oscillator 1 is an analog oscillator, and is hardwired to the Left channel. Following are
the main controls for Oscillator 1. Note that there are some additional modulation
controls that will affect Oscillator 1 – these are found in different sections of the
Parameter definitions.
Frequency: 1 1 C…C8 Selects base frequency over a 10 octave range, from 8
Hz to 8KHz, stepping in semitones. C3 is middle C, the first octave has no number (c ,
db , d …), the second octave is –1 (c -1, db-1, d -1…), the third is zero (c 0, db0,
d 0 …), etc.
Fine: 1 2 -50…+50 Fine Tune control; 0 centered. Steps in cents (50 cents = ½
semitone).
