Miscellaneous
There are different ways to control the Poly 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. It can get more complicated in a Combo, but here we are just discussing
the Program side of things.
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.
In the Poly (different from the Evolver) some of the Trigger modes will automatically
turn the Sequencer on. This allows gated-sequence Programs to be played without
having to manually hit the S

button. The Trigger modes that do this are
marked in the table as AUTO .
Trigger:
see table Selects the source of triggers/gates for the envelope
generators.
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. AUTO .
Ext G r
External In signal will gate the sequencer, 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.
