Dave Smith Instruments EVOLVER - Manual (Page 33)

Trigger/Interface Parameters
There are different ways to control Evolver; using the internal sequencer, using
external MIDI controllers (keyboards, computers, etc), or using external audio
sources. And, there are ways of combining these, such as gating the sequencer from
a keyboard.
Control consists mainly of triggers for the envelopes, and note numbers for the
oscillators. Beyond that there are all the additional modulation sources/destinations
and MIDI controls. Following are the parameters used to select the different control
modes.
Trigger Sel: 7 7 see table Selects the source of triggers/gates for the envelope
generators.
Display Envelope Trigger Selections
all The envelopes will be triggered by either the sequencer or MIDI
notes. When triggered by the sequencer, the gates are on for half the
step time. Simply adjust the envelope parameters (ADSR) for the
desired effect.
seq The envelopes will be triggered by the sequencer only.
m iid The envelopes will be triggered by MIDI notes only.
m idr The envelopes will be triggered by MIDI, and the sequencer will be
reset on every note (if it is running). The sequencer will not trigger
the envelopes.
m is Combo mode – the envelopes will only be triggered when a MIDI
note is held and the sequencer is running; in other words the MIDI
notes will gate the sequencer. AUTO (S
TART LED goes on)
m isr Combo mode 2 – same as Combo, except every time a MIDI note is
hit, the sequencer is reset to step 1. AUTO
E i The envelopes are gated by the Left external audio input signal level,
in other words, when the signal gets above a fixed threshold, the
envelopes start. The envelopes then go into the phase when the
signal level drops below a second fixed threshold.
E ir Same as external in, but also resets the sequencer to step 1.
E iS External In signal will gate the sequencer (sequencer must be on).
AUTO
E sr External In signal will gate the sequencer (sequencer must be on).
And also resets the sequencer to step 1 on each new gate. AUTO
m isi Plays a sequence once (according to the length of Sequence 1)
when a new MIDI note is received. The sequence is not restarted on
multiple MIDI notes until it finishes and stops. AUTO
m i1r Also plays a MIDI sequence once, but will re-start the sequence on
each MIDI note. AUTO
E iC Plays one step of the sequencer on each External Input audio trigger.
AUTO
m in C Plays one step of the sequencer on each key hit. AUTO
