LFOs
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.

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.
