- Programs 80 – 128 are sounds meant to played from a keyboard; some have sequences programmed, and some do not. Most respond in different ways to keyboard pressure and mod wheel.

- Sequencer Operation
- While the sequencer is running, if you hold the Shift button when you hit the Stop button, the sequence will continue running until finished (according to the length of Sequence 1), and will stop after playing step 1.
- A simple “tap tempo” feature is available. With the sequencer off, hold the Reset button, and then hold the Start/Stop button for a count of four; then lift up the Start/Stop button in time. The sequencer will start with the new tempo. Note – the actual speed will depend on the Clock Divide setting. The count will match if Clock Divide is set to 4n. If set to 8n, it will play twice as fast as your “tap”, and so forth.

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.
miid
The envelopes will be triggered by MIDI notes only.
midr
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.
mis
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 (START LED goes on)
misr
Combo mode 2 – same as Combo, except every time a MIDI note is
hit, the sequencer is reset to step 1. AUTO
Ei
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.
Eir
Same as external in, but also resets the sequencer to step 1.
EiS
External In signal will gate the sequencer (sequencer must be on).
AUTO
Esr
External In signal will gate the sequencer (sequencer must be on).
And also resets the sequencer to step 1 on each new gate. AUTO
misi
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
mi1r
Also plays a MIDI sequence once, but will re-start the sequence on
each MIDI note. AUTO
EiC
Plays one step of the sequencer on each External Input audio trigger.
AUTO
minC
Plays one step of the sequencer on each key hit. AUTO
