Display  Envelope Trigger Selections 
Sq or MD 
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. 
Sequencr 
The envelopes will be triggered by the sequencer only. 
MIDI 
The envelopes will be triggered by MIDI notes only. 
MIDI rst 
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. 
MID Gate 
Gated 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 
MIDI G r 
Gated mode, reset – same as Gated mode, except every time a 
MIDI note is hit, the sequencer is reset to step 1. AUTO 
Ext In 
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 
release phase when the signal level drops below a second fixed 
threshold. 
Ext In r 
Same as external in, but also resets the sequencer to step 1. 
Ext Gate 
External In signal will gate the sequencer (sequencer must be 
on). AUTO 
Ext G r 
External In signal will gate the sequencer (sequencer must be 
on). And also resets the sequencer to step 1 on each new gate. 
AUTO 
MS Once 
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 
MS Once R 
Also plays a MIDI sequence once, but will re-start the sequence 
on each MIDI note. AUTO 
EiSqStep 
Plays one step of the sequencer on each External Input audio 
trigger. AUTO 
MdSqStep 
Plays one step of the sequencer on each MIDI note received. 
AUTO 
Key Off/Tran: Off, -36…+36  Enables and transposes MIDI notes. If 
Off, MIDI notes are ignored. Otherwise, it transposes midi notes from –36 to +36 
semitones (+/- 3 octaves). 
Note – this is an important parameter! When this is off, MIDI notes will not work. 
This parameter, with the Trigger Select (above) are the main controls for selecting 
how Evolver plays. 
Another note – you will find that there are other interactions between the 
sequencer and MIDI. For example, if you make a Program using the sequencer, 
you will likely set the Oscillator frequencies up to the desired pitch range. But, if 
you then try to play this Program from a keyboard, the pitches will likely be too 
high. Rather than lowering all the oscillator frequencies (which would mess up the 
sequence!) you can simply use the transpose here.
