- Programs 80 – 128 are sounds meant to played from a keyboard; some have sequences programmed, and some do not. Most respond in different ways to keyboard pressure and mod wheel.

- Sequencer Operation
- While the sequencer is running, if you hold the Shift button when you hit the Stop button, the sequence will continue running until finished (according to the length of Sequence 1), and will stop after playing step 1.
- A simple “tap tempo” feature is available. With the sequencer off, hold the Reset button, and then hold the Start/Stop button for a count of four; then lift up the Start/Stop button in time. The sequencer will start with the new tempo. Note – the actual speed will depend on the Clock Divide setting. The count will match if Clock Divide is set to 4n. If set to 8n, it will play twice as fast as your “tap”, and so forth.

Oscillator 4
Oscillator 4 is a digital waveshape oscillator, and is hardwired to the Right channel.
Like the Prophet VS, the digital oscillators in Evolver get quite trashy at higher
frequencies. Following are the controls for Oscillator 4:
Frequency: 2 5 C…C8 Selects base frequency over a 10 octave range, from 8
Hz to 8KHz, stepping in semitones. C3 is middle C, the first octave has no number (c ,
db , d …), the second octave is –1 (c -1, db-1, d -1…), the third is zero (c 0, db0,
d 0 …), etc.
Fine: 2 6 -50…+50 Fine Tune control; 0 centered. Steps in cents (50 cents = ½
semitone).
Shape/PW: 2 7 1…128 Selects a digital waveshape. Waveshapes 1 - 95
correspond to ROM (preset) Waveshapes 32 – 126 in the Prophet-VS. Waveshapes
97 – 128 are user programmable via the software editor. In the VS, the user waves
were 0 - 31, and wave 127 was noise, which is not included because the Evolver has
a separate noise generator. Wave 96 has a Waveshape that is unique to Evolver in
place of the VS noise. Wave 95 (126 on the VS) is a “blank” wave, which can give
some options while sequencing waves. The Evolver ships with waves 97 – 128 the
same as 1 – 32.
Level: 2 8 0…100 Sets the volume of oscillator 4.
Glide: 2 5 S 0…100; F02…F99; OFF The oscillator 4 Glide rate; low numbers
are faster. Normal Glide covers the range from 1 to 100 (0 is no glide). A “fingered”
mode that only glides when more than one note is held down is selected by setting
glide over 100, where it ranges from F02 to F00 (equivalent to glides of 2 to 100).
Thought not quite Glide related, if you set glide all the way to maximum, it goes to
OFF, which has the effect of disconnecting oscillator 4 from MIDI.
FM 3->4: 2 6 S 0…100 The amount of Frequency Modulation of Oscillator 4
from Oscillator 3. Note that both digital oscillators can FM the other at the same time
for some wild results.
Shape Seq: 2 7 S Off, SE1..4 This parameter allows sequencing Waveshapes.
Off if not in use, otherwise select one of the four sequences se1, se2, se3, or se4 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 3->4: 2 8 S 0…100 The amount of Ring (Amplitude) Modulation of
Oscillator 4 from Oscillator 3. Note that both digital oscillators can modulate the other
at the same time.
