Low Frequency Oscillator (Lfo) Settings - Alesis Micron Reference Manual

12. Low Frequency Oscillator (LFO) settings

TempoSync (Tempo Synchronization)
fixed rate
The LFO rate is independent of the tempo set with the [tap]
button.
follow tempo
The LFO's rate is a multiple of the tempo set with the [tap]
button.
If TempoSync is off, the rate is adjustable from 0.010 – 1000 Hz
(cycles per second).
If TempoSync is on, the rate represents a fraction of the tempo
set with the [tap] button. When the value is set to x 1 ("times
one"), the LFO will complete its cycle once per quarter note,
relative to the tempo setting. When the value is set to x 2, the LFO
will cycle once per eighth note. A value of x 16 results in an LFO
cycle of 1/64th note, and a value of x 1/ 16 results in an LFO
cycle equivalent to sixteen quarter notes.

To jump to the Low

category, hold down the
[programs] button and press
the key labeled "LFO."
It's bipolar. (No it's not.
Yes it is. No it's not.)
Synthesizer LFOs can be
either "unipolar" (rising and
falling in the >= 0 range) or
"bipolar" (rising and falling
through both positive and
negative values).
The Micron's LFOs are
bipolar. You can make them
act like unipolar designs by
programming a
counteracting positive offset
in the modulation matrix.
(Just don't change the LFO
modulation amount once
you've done this, or your
offset won't be accurate
anymore.)
