Waveform
(WAVEFORM)
[Triangle…Random6 (Continuous)]
Most of the waveforms are self-explanatory, but a few will benefit from more details:
GTR (Guitar)
is intended for guitar vibrato. It is positive-only, so that when used for pitch, it only bends upwards.
RND 1 (Random 1)
generates traditional sample and hold waveforms: random level changes with steady timing.
RND 2
(Random 2)
randomizes both levels and timing.
RND 3 (Random 3)
generates a pulse wave with random timing.
RND 4-6
are smoothed versions of
Random 1–3
, with slopes instead of steps. Use them to create gentler random
variations.
LFO Waveforms
Start Phase
[-180…+180]
This controls the phase of the waveform at the start of the note. If
Random Start Phase
is
On
, this parameter has no
effect.
Rndm° (Random Start Phase)
[Off, On]
When
Random Start Phase
is
On
, the LFO will start at a different, random phase every time.
Offset
[–100…+100]
By default, almost all of the LFO waveforms are centered around 0, and then swing all the way from -100 to +100.
Offset
lets you shift the LFO up and down, so that—for instance—it’s centered on 50, and then swings from -50 to
+150.
For example, let’s say that you’re using an LFO for vibrato. If
Offset
is
0
, the vibrato will be centered on the note’s
original pitch, bending it both up and down.
If
Offset
is
+100
, on the other hand, the vibrato will only raise the pitch above the original note.
