User Manual

Note - though the sequences are named 1-4, there is really only one
sequence that has four different controls, each of which can be routed to a
different destination via the four Sequence Destination parameters (bottom
left corner). In other words, one sequencer with four individual outputs that
act in parallel. Each of the four can be a different length. Sequence 1 (rows 1
and 2) controls whether a step acts as a rest (by not triggering the
envelopes). Check page 18 for more information on the sequencer.
Using Evolver with a MIDI Keyboard
Evolver is quite often used without a keyboard, just using the internal sequencer.
Other times, it is used solely from a keyboard. It can also be used in combination,
with the keyboard gating the sequencer, for example. To accommodate these
different uses, there are a couple Program parameters to select triggering modes
and oscillator frequency ranges.
The Trigger Select parameter selects the source for triggering the envelopes. It is
usually set to
ALL to allow triggers from either the sequencer or from MIDI. The
Key Off/Transpose parameter provides an easy way to turn off the MIDI notes for
use with the sequencer only. So, to use a MIDI source, you must make sure this
parameter is not off! The same parameter provides MIDI transposing plus/minus
three octaves. See page 33 for more information on these two parameters.
Programs 70 through 127 in Bank 1 are sequences that are set up to play with
MIDI notes. All Programs in Bank 2 are meant to play from a keyboard, with Pitch
and Mod wheel and Pressure all enabled, and no sequences.
Note - the right decimal point in the display flashes whenever anything comes
in MIDI input jack. Note that it flashes even when MIDI input is disabled.
Using Evolver as a Signal Processor
Simply plug your sound source into the External Inputs. If you are using a mono
signal, you will need to select single channel operation with the External Input
Mode parameter (Row 8, knob 7). You may also need to adjust the input gain –
select the second Main row by hitting the M
AIN button once, and select 0 to 24 db
of gain using the Input Gain knob. Note that the row and column LEDs act as a
very simply VU meter when adjusting the gain; this helps set the optimum levels.
Ideally you want the clip LED to come on occasionally.
Usually for signal processor use, you will have the VCA Level turned up;
otherwise the signal will not get through. Other options are to use the signal to
trigger the envelopes (using Trigger Select), or using the Envelope follower
routed to VCA Level.
Summary
You should be up and running now; for more operation information, read on. Or,
just look up specific parameters for detailed notes, or to decipher some of the
more convoluted displays. Pages 38 through 40 contain a handy reference for
mod destinations and sources. At some point you should read through the
manual to discover all the little features that you might not notice at first.
