- 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.
