To program a sequence:
1. Press the G
ATED
S
EQUENCER
switch and press a key to play the
sequence. You may also want to adjust the C
LOCK
D
IVIDE
and BPM
settings.
2. Press E
DIT
S
EQUENCER
to enter sequence edit mode.
3. Select the sequence you want to program by pressing the appropriate
switch (1, 2, 3, or 4 in Modulators).
4. Select the destination for that sequence using the M
OD
D
EST
. For
example, to generate a sequence of notes, select OscAllFreq.
When a sequence is routed to oscillator frequency, each knob increment
equals half of a semitone. The LCD display will show the relative note
value, with a “+” after it to show when at a half-semitone step.
5. Turn the Step 1 knob to the desired value.
As the sequence loops, you will hear your edits.
6. Repeat for each subsequent step in the sequence.
7. Choose another sequence and follow the same basic steps until you’re
happy with the results.
8. Dont forget to write your edits to memory! Sequences are saved with
the related program. Just press Write and then Yes to save the program
and sequences.
More Sequencer Parameters
The previous section covers the basics of sequencer programming, but there are
some additional parameters that affect the sound and user interaction with the
sequencer.
Slew
In modular analog synthesizers, a lag processor or slew limiter is used to create
a time-varying change—a smooth transition—between successive, discrete
control voltage levels. The rate of change is called the slew rate and one
common application is to create a glide (aka portamento) effect between notes.
Among the possible destinations for Prophet ’08 sequences two and four is a
sequence-only parameter called Slew. Slew behaves a little differently from the
other modulation destinations, in that it is not really a destination at all; instead,
it affects the sequence above it. That is, if Slew is the chosen destination for
