- 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.

Amount:  6 3 0…100, 1…100   Sets the amount of LFO, 0-100. When you go 
past 100, the scale starts over at 1, but now Key Sync is on. This means that this LFO 
will restart every time you hit a key. 
Destination:  6 4 see table  LFO 1 destination - see the Modulation Destination 
table on page 38 for a list of possible destinations. 
Envelope 3 
Envelope 3 is a general purpose envelope for modulation purposes.

Destination:  7 2   see table Envelope 3 destination - see the Modulation 
Destination table on page 38 for a list of possible destinations.
