Depending upon the BPM and Clock Divide settings, the slew rate can actually
exceed the time the envelopes are gated on, causing a step in the affected sequence
to not reach its set value. For example, if Slew is applied to oscillator frequency, high
Slew values may cause a step to sound flat or sharp. If that’s not what you want,
simply reduce the Slew value.
Sequencer Parameters
Type: Gated, Poly—
This switch toggles between the polyphonic
sequencer and the gated sequencer.
Play:
On, Off—
This switch starts and stops polyphonic sequencer playback.
Record: On, Off—
This switch turns sequencer recording/editing on and
off on the polyphonic sequencer.
Destination: Various—
In the gated sequencer, this button allows you to
select a modulation destination for the currently selected track. Destina-
tions appear in the display. Use the
value
knob to choose the destination.
Track: 1, 2, 3, 4—
This knob allows you to select a track for recording or
editing.
Mode: Normal, No Reset, No Gate, No G/R,Key Step—
Selects one of
the following operation modes for the gated sequencer:
Normal: Good for melodic and rhythmic sequences. With each step, the
envelopes are retriggered, so works best with shorter envelop contours. Each
new key press/received MIDI note starts the sequence for that key/note at step
one. When programming melodies, the note value you select is relative to the
note/key played, and not the actual note played back for that step. For example,
if you set track one to
osc all freq
., and set step one to C2, playing Middle C
on the keyboard will produce C two octaves above middle C on step one. A
value of C0 will produce the exact note that you play on the keyboard. A value
of G0 will produce the note a 5th above what you play on the keyboard.
No Reset: Same as Normal, except that new key presses/received MIDI
notes do not begin the sequence for that note at step one. In this sense,
the gated sequencer is free-running in No Reset mode. This makes is less
useful for melodies, but still great for rhythmic parameter changes.
No Gate:
In this mode, the envelopes respond to the keyboard/received
MIDI notes, and not by each advancing sequencer step. This mode is great
for complex parameter modulation of sounds with long envelope contours,
such as pad sounds. Each new key press/received MIDI note starts the
sequence for that key/note at step one.
No Gate No Reset:
Same as No Gate, except that new key presses/
received MIDI notes do not begin the sequence for that note at step one.
Key Step:
Striking any key or playing a note via MIDI advances the
sequencer one step.
Clock Parameters
BPM: 30…250—
Sets the tempo for the sequencer and arpeggiator in BPM
(beats per minute). The
tap tempo
LED flashes at the BPM rate. When
lfo
sync
is turned on, the BPM rate affects the LFO frequency. When syncing to
an external MIDI clock source, the BPM setting has no effect.
Tap Tempo: 30…250—
Tap this button at least 4 times to quickly set the
tempo for the sequencer and arpeggiator. The LED flashes at the BPM
rate you set.
Divide:
Sets the note value for each sequencer/arpeggiator step relative
to the BPM.
divide
works with both internal and external clock sources.
The following table lists the values:
Name Tempo Timing Division
Half BPM/2 Half note
Qtr BPM Quarter note
8th BPM x 2 Eighth note
8th Half BPM x 2 Eighth note, half swing timing
8th Swing BPM x 2 Eighth note, full swing timing
8th Trip BPM x 3 Eighth note triplets
16th BPM x 4 Sixteenth note
16th Half BPM x 4 Sixteenth note, half swing timing
16th Swing BPM x 4 Sixteenth note, full swing timing
16th Trip BPM x 6 Sixteenth note triplets
32nd BPM x 8 Thirty-second note
32nd Trip BPM x 12 Thirty-second triplets
64th BPM x 16 Sixty-fourth note
