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
P
AGE
U
P
and P
AGE
D
OWN
buttons step through parameter groups.
Note: If you hold the P
AGE
D
OWN
button while you hit the P
AGE
U
P
button, it will
jump to the last page. Similarly, if you hold the P
AGE
U
P
button when you hit the
P
AGE
D
OWN
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
