Suggested Destinations
You can really have some fun with other destinations. For example, route a sequence
to Delay amount to have the delay level change; or to feedback amount to drastically
change the sound every step. FM and Ring Mod Levels are fun to sequence, too—
you get the idea. With four sequences, you can program a very dynamic sequence.
Another very useful way to modulate a sequence is using LFOs with sync; LFO
frequency runs 0-150, after which you can select the sync settings. A setting of 16
Steps for LFO Frequency with a Triangle wave selected and routed to the filter will
provide a clean filter sweep over a 16 step sequence, perfectly in sync! This is much
easier (and smoother) than programming a filter sweep using sequence steps.
The sequencer can also be routed to MIDI output destinations, including Note
Number, Velocity, Mod Wheel, Pressure, Breath, and Foot Controller. Velocity is a
special case – it only works if selected as the destination for Sequence 2 when
Sequence 1's destination routed to Note Number. The same for Sequence 3 and 4
(Sequence 4 can be velocity for Sequence 3). If velocity is not used as a destination,
the velocity output is 120. So, it is possible to have up to 4 note sequences sent out
over MIDI.
The actual MIDI note transmitted is the sequence step value plus one (since MIDI
note on of zero = note off). Note that this is different than the half-semitone when
driving the internal oscillators—this was done to provide a wider range of notes. Also,
the main Transpose is added to/subtracted from the MIDI note output. Velocity and
the other controllers are converted from 0 - 100 range to 0 - 127 range for MIDI.
Another possible sequencer destination is Clock Mod. It works via a multiplier based
on a step value of 40. If a sequencer step is set to 40, the clock speed stays as set. If
set to 20, (half of 40), the clock will be twice as fast for that step. Likewise, a step
value of 80 will be twice as slow as normal, and 10 would be 4 times faster.
Note that overall limits of 30 to 250 BPM still apply; for example, if you have a BPM of
120, and a sequencer step of 10, it will try to go four times faster than 120, which is
480. Since it is greater than 250, it will clamp at 250. With clever choices of BPM
(using Clock Divide as necessary) you can develop a pretty wide range of timing
possibilities. Also, with sequences of different lengths, it can really get quite wild.
