PLAYING SEQUENCES
Push RUN to start playing a sequence. The RUN LED will turn ON. Pressing RUN again will pause the sequence at
the current step and the RUN LED will turn OFF. The sequencer steps can be programmed while paused.
Press RESET to stop the sequence, go to step 1, and enter Ready mode. The STEP LED will BLINK to let you know
that you are in Ready mode. Now when you press RUN again, the sequencer will play starting at step 1 on the
next clock pulse.
To start on a different step, use the STEP LEFT and STEP RIGHT buttons to pick a different one.
While in Ready mode, you can use the note/keyboard buttons to manually play tunes without changing the
sequence stored in memory. Gate timing will follow your button presses.
CLOCK (Internal / External)
The 3650 includes a handy (but somewhat limited) internal clock, which is activated when the sequencer is first
powered on, or after a soft-reset. For greatest flexibility, you may wish to consider using an external clock via
the CLOCK IN jack.
When an external clock pulse is received, the internal clock is automatically disabled. To reactivate the internal
clock, press and hold the RESET button for about 2 seconds (this soft-resets the sequencer).
CLOCK TEMPO (Internal)
The STEP buttons increase and decrease the internal clock speed while a sequencer is running. Internal clock
tempos are approximate:
