Dave Smith Instruments MONO EVOLVER KEYBOARD - Manual (Page 28)

LFOs
The Evolver has four identical Low Frequency Oscillators (LFOs). To select a specific
LFO for editing, press the appropriate switch, 1-4. Turning a knob will then adjust the
parameters of the selected LFO.
Note: Holding one of the four switches will solo that LFO (the switch will blink) by
setting the Amounts of the other three to zero. It does not affect any modulation
that is routed to LFO Amounts, though, so at times it may not completely turn off
all other Amounts.
Frequency: 0…150, sync – Sets the LFO frequency. Range 0-150 for un-synced
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 may not respond well to the fastest LFO
speeds, due to speed limitations of the control voltages; but they will certainly
generate some interesting sounds.
Above 150, the sync speeds are as follows:
Display Timing Sync
32 Steps Sequence speed divided by 32; i.e. one LFO cycle
takes 32 steps
16 Steps Sequence speed divided by 16
8 Steps Sequence speed divided by 8
4 Steps Sequence speed divided by 4
2 Steps Sequence speed divided by 2
1 Step One cycle per step
1/2 Step Two cycles per step
1/4 Step Four cycles per step
1/8 Step Eight cycles per step
1/16Step Sixteen cycles per step
Shape: see table – Selects the LFO waveshape:
Display LFO Shape
Triangle Triangle
Rev Saw Reverse Sawtooth
Sawtooth Sawtooth
Square Square Wave
Random Random – changes once per cycle for
sample-and-hold effects
Amount: 0…100 – Sets the amount of LFO routed to the destination.
Key Sync: When this switch is enabled (lit) the Evolver re-starts the LFO each time a
new note is played (Key Sync). Key Sync on each LFO can be set independently.
