Program Parameters


The Poly has 128 parameters in a Program, plus another 64 Sequence parameters,
followed by the 16 character Program Name. These parameters are the same as in
Evolver. Following is a description of every parameter.

The upper knob selects the Parameter, and the lower knob changes the value. The

buttons step through parameter groups.

Note: If you hold the P

P

button, it will

jump to the last page. Similarly, if you hold the P

button, it will jump to the first page.


The parameters are listed in this section in groups according to the pages; the upper
LCD line displays the current page, and the lower line shows the parameter name and
value.

Oscillator 1


Oscillator 1 is an analog oscillator, and is hardwired to the Left channel. Following are
the main controls for Oscillator 1. Note that there are some additional modulation
controls that will affect Oscillator 1 – these are found in different sections of the
Parameter definitions.

Frequency:

C -2…C 8 Selects base frequency over a 10 octave range,

from 8 Hz to 8KHz, stepping in semitones. C3 is middle C, the first octave is –2 (c -2,
c#-2, etc.), the second octave is –1 (c -1, c#-1, etc.), the third is zero (c 0, c# 0…),
etc.

Fine Freq:

-50…+50 Fine Tune control; 0 centered. Steps in cents (50

cents = ½ semitone).

Shape:

see table Selects the analog waveshape as follows:

Pulse xx

Pulse Wave, with pulse width ranging to minimum (0) to
maximum (99). The pulse width will turn off at the two
extremes – this allows some interesting modulation
possibilities. A square wave will be around P50.

Level:

0…100 Sets the volume of Oscillator 1.

Glide:

0…100; F02…F99; OFF The oscillator 1 Glide rate; low numbers are

faster. Normal Glide covers the range from 1 to 100 (0 is no glide). A “fingered” mode
