Dave Smith Instruments MOPHO KEYBOARD - Manual (Page 31)

Note: 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 Trigger Modes
The Sequencer Trigger mode determines how the sequencer reacts to triggers
and what constitutes a trigger. Sequencer Trigger is found in the Miscellaneous
Parameters section. The different modes are:
Normal– A note on, from either the local keyboard or via MIDI, causes the
sequencer to play from the first step. The sequencer resets to step one each time
a new note is played. Each sequence step gates the envelopes.
No Reset– As above, but the sequencer does not reset to step one for each note
played. The sequencer is effectively free running.
No Gate– The keyboard gates the envelopes, but the sequencer does not. The
sequencer resets to step one each time a new note is played.
NoGateNR– As above, but the sequencer does not reset to step one for each note
played. Again, the sequencer is effectively free running.
Key Step– Striking any key or playing a note via MIDI advances the sequencer
one step.
Audio In– Steps the sequencer and gates the envelopes when a signal at Audio In
exceeds a preset threshold. External Volume does not affect the trigger and can
be set at minimum. External Gain does boost the signal prior to the threshold
detector and so will affect the triggering. And the level of the input signal will
also have an effect.
Syncing an LFO to the Sequencer
One very useful way to modulate a parameter in sync with a sequence is using
an LFO with Clock Sync. 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 manually programming a sequence to sweep the filter.
