- 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.

Miscellaneous Modulation Parameters
Seq 1 Dest: 8 1 see table Sequence 1 Destination - see the Modulation
Destination table on page 38 for a list of possible destinations.
Seq 2 Dest: 8 2 see table Sequence 2 Destination
Seq 3 Dest: 8 3 see table Sequence 3 Destination
Seq 4 Dest: 8 4 see table Sequence 4 Destination
Osc Slop: 1 6 S 0…5 The amount of random oscillator frequency slop. The
analog and digital oscillators in Evolver are very accurate, and will not drift. This works
great for accurate sounds, and allows precise de-tuning. The Oscillator Slop
parameter allows subtle amounts of frequency drift. For larger amounts, use a random
LFO or white noise mod.
Exp/Lin Env: 4 1 S Exp, Lin Selects whether all three envelopes have a linear
(straight line) shape, or exponential (curved). Exponential is the more natural of the
two.
Mod 1 Source: 3 6 S see table General purpose modulation source select – see
list on page 40 for possible sources. Since all mod sources in Evolver have a single
destination, the four general purpose Mods allow a method to send a mod source
(such as a sequence or LFO) to another destination, with a different amount. Also,
there are some additional mod sources such as noise and the digital oscillators
available, allowing audio-rate modulation. As mentioned above, there are some
destinations that are not able to keep up with audio mod, but it’s fun anyway.
Note - these mod sources are not filtered, so a MIDI controller going through this
route will react quicker, but may produce stepping noise, depending on the
controller. For filtered (smoothed) MIDI controller operation, use the direct
Pressure, Mod Wheel, Breath Control, or Foot Control parameters.
Mod 1 Amt: 3 7 S -99…+99 Amount of Mod 1 modulation.
M1 Destination: 3 8 S see table Mod 1 Destination - see the Modulation
Destination table on page 38 for a list of possible destinations.
Mods 2 – 4: Same as Mod 1
