Sequence one has an additional value, Rest, that appears in the list after Reset.
Rest prevents the envelopes from being gated by the corresponding step, so a
rest in sequence one affects all four sequences. If the sequences are the same
length, rests will occur in the same place in all four sequences as they loop. If
the sequences are different lengths, the rests in sequence one apply to whatever
the current step happens to be in sequences two through four, resulting in a more
random-sounding pattern (which can be really cool). In the following example,
sequence one is 16 steps long and rests occur at steps 2, 6, 9, and 12. However,
sequence two is only eight steps long, so rests occur at steps 2 and 6 the first
time it plays through and then at steps 1 and 4—corresponding to steps 9 and 12
in sequence one—the first time it repeats. As sequence two loops, the rests will
continue in the same alternating pattern.

Programming the Sequencer

Programming the sequencer is easy, but there are a few things to consider before
you start. Most importantly, what do you want the sequence to do and what
modulation destinations will provide the results you’re seeking? For example, is
the sequencer going to control oscillator frequency? One sequence can control
the frequency of both oscillators or one sequence can control oscillator 1 and
another sequence can control oscillator 2 for harmonies or countermelodies. A
typical application of the sequencer might have sequence one routed to the
frequency of both oscillators, sequence two routed to filter cutoff, sequence
three routed to filter resonance, and sequence four routed to amplifier envelope
amount for accents. Many of the factory programs have sequences programmed,
so you can refer to those to see how certain effects are being achieved.

To program a sequence:

1. Turn the sequencer on.

2. Choose Sequencer in the Modulation section.

3. Choose the sequence to program: 1, 2, 3, or 4.

4. Play a note to start the sequence playing.
