Program Parameters; Analog Oscillators (1 And 2) - Dave Smith Instruments Evolver Operation Manual

Program Parameters

All Program parameters can be edited using the front panel controls. To edit a
program, simply turn the desired parameter knob. The selected parameter and value
appears in the LCD display.
After a parameter is selected by turning its knob, you can also use the P
to change the value of the selected parameter. The +/Y
incrementally adjust parameter values as well.
Note: Hit both +/Y
Following are descriptions of each Evolver Program parameter.
Oscillators
There are four oscillators in the Evolver voice. To select a particular oscillator for
editing, press the appropriate oscillator switch, 1-4. Turning a knob will then adjust the
parameters of the selected oscillator.
Note: Holding one of the four switches will solo that oscillator (the switch will blink)
by setting the levels of the other three to zero. It does not affect any modulation
that is routed to oscillator level, though, so at times it may not completely turn off
all other levels.
Oscillators 1 and 2
Oscillators 1 and 2 are analog oscillators. Oscillator 1 is hardwired to the Left channel;
Oscillator 2 is hardwired to the Right channel.
Note: There are additional modulation controls that affect Oscillators 1 and 2.
These are covered in other sections of the Parameter definitions.
Frequency: C -2...C 8 – Selects the base oscillator 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, and so on), the second octave is -1 (C-1, C#-1, and so on), the third is
zero (C 0, C# 0...), and so on.
Fine: -50...+50 – Fine Tune control; 0 centered. Steps in cents (50 cents = ½
semitone).

Pulse Wave, with pulse width ranging from 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 Pulse 50.
