FM 4 -> 3: 0…100 The amount of Frequency Modulation of

Oscillator 3 from Oscillator 4. Note that each digital oscillator can FM the other at the

same time for some wild results.

Shape Seq: Off, SE1..4 This parameter allows sequencing Waveshapes.

Off if not in use, otherwise select one of the four sequences Seq 1, Seq 2, Seq3, or

Seq 4 to change the waveshape on every sequence step. In other words, if sequence

1 is selected, with step 1 = 10 and step 2 = 5, then waveshape 10 will play in the first

step, and waveshape 5 will play in the second.

Ring Mod 4>3: 0…100 The amount of Ring (Amplitude) Modulation of

Oscillator 3 from Oscillator 4. Note that each digital oscillator can Ring modulate the

other at the same time.

Oscillator 4

Oscillator 4 is a digital waveshape oscillator, and is hardwired to the Right channel.

The parameters for Oscillator 2 are the same as Oscillator 1 above, except the FM

and Ring Mod parameters go in the opposite direction.

Lowpass Filter

The analog (real analog!) lowpass filter is actually two different filters; one for the Left

channel and one for the Right channel. This allows true stereo processing of external

audio signals run through Evolver. However, for simplicity and consistency the two

filters are driven together in tandem, so they normally respond the same way.

Exceptions are when using the Spilt parameter as noted below, and when using the

separate filter cutoff and resonance modulation destinations, which allow the two

filters to be modulated independently. Note that though they are normally controlled

together, since they are analog there will always be some subtle differences between

the two filters, which gives the Poly Evolver a more natural sound.

Frequency: 0…164 Selects base filter cutoff frequency over more than 13

octaves. There is special smoothing on the operation of the filter knob to eliminate

stepping as you turn the knob for clean manual filter sweeps.

Resonance:

0…100 Sets the Resonance level of the filter; at high settings

the filter will self-oscillate in 4-pole mode. If the filter does not oscillate, make sure that

4 pole mode is selected.

Config: 2 Pole, 4 Pole Selects either 2 or 4 pole operation for the filter.

Envelope Amt: -99…+99 Amount of filter envelope to the cutoff frequency.

This can be positive or negative, allowing inverted envelope control of the filter.

Env Velocity: 0…100 Amount of MIDI velocity controlling the level of

the filter envelope.
