Time 2:

0…150, sync Sets the delay time of the second delay tap, same

ranges as Time 1.

Level 2:

0…100 Sets the delay amount of the second delay tap.

Time 3:

0…150, sync Sets the delay time of the third delay tap, same ranges

as Time 1.

Level 4:

0…100 Sets the delay amount of the third delay tap.

Feedback 1:

0…100 Amount of feedback from the summed output of all

the delay taps to the input of the delay.

Feedback 2:

0…100 Amount of feedback from the summed output of all

the delay taps to the input of the filter for more extreme effects.

LFO 1


There are four identical Low Frequency Oscillators (LFOs) in Evolver. Following is the
description of LFO 1; the other three have the same four parameters.

Freqncy:

0…150, sync Selects the frequency of LFO. Range 0 – 150 for

unsynced LFO; speed ranges from slow (30 seconds) to very fast – at 90 (8 HZ, C-2)
and above the speed steps in semitones, up to 150 (261 Hz, middle C).

Note - some of the analog functions can’t respond very well to the fastest LFO
speeds, due to speed limitations of the control voltages; but it will certainly
generate some interesting sounds.

Above 150 are the sync speeds as follows:
