Controls

 

1. LED: Light-emitting diodes indicate speed, type and position of sequence.

2. Position Tuning Sliders: Allow performer to tune individual steps via variable slider.

3. Gate Bus Switches: These can be used for: skip, reset function; controlling rate of internal
clock (produces complex rhythms); triggering a synthesizer's envelope generators; opening
VCFs, VCAs fdr accents.

4. Internal Clock: Controls speed and rhythmic variation of sequence. Voltage controlled.

5. Various Gate Jacks: Used for trig·erig: a synthesizer's envelope generators.

6. Ouantizer: A two-channel devicc that rounds off the voltage received from the sequencer
position outputs to ttie neni-es· 1/12th volt. Eni·bles performer to tune in perfect chromatic increments.

7. Multiple: Splits any signal irito four outputs.

8. Step/Reset: Step moves position of sequrnce one step forward. Reset places sequence back to position 1.

9. Sequential/Random: In the sequential mode, the sequence moves in an orderly stepped pattern. The
random continuously changes its position.

10. 16/1, 8/2 Switch: In the 16/1 mode, a16-note sequence is possible. In the 8/2 mode, both the A and B
banks are stepped in eight positions in parallel. Allows the performer to tune an eight-note melody in bank
A and a discrete eight-note harmony in bank B.
