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:
