PROGRAM > LFO
Each of the Oscillators has two LFOs, which you can use to
modulate the filter, amp, pitch, and many other parameters.
The two Oscillators also share a single Common LFO,
similar to the global LFO on some vintage analog synths.
These pages let you set up all of the parameters for all five
LFOs.
5–1: OSC1 LFO1
This page has all of the controls for the first LFO of
Oscillator 1. For instance, you can:
• Select the LFO’s basic waveform, and modify it with the
Shape parameter.
• Control the LFO’s frequency, and assign AMS
controllers to modulate the frequency.
• Use the Key Sync parameter to choose whether the LFO
runs separately for each voice, or is synchronized across
all of the voices
• Use the Fade and Delay parameters to control how long
the LFO waits to start after note-on, and whether it starts
abruptly or fades in slowly.
• Set the LFO to sync to MIDI tempo.
5–1a: OSC 1 LFO 1
Waveform [Triangle…Random6 (Continuous)]
This selects the basic LFO waveform, as shown in the
graphic below.
Most of the waveforms should be self-explanatory, but a few
will benefit from more details:
Guitar is intended for guitar vibrato, and its shape is
specifically tuned for this purpose. The waveform is
positive-only, so that when used for pitch, it will only bend
up, and not down.
Random1 (S/H) generates traditional sample and hold
waveforms, in which the level changes randomly at fixed
intervals of time.
Random2 (S/H) randomizes both the levels and the timing.
Random3 (S/H) generates a pulse wave with random
timing. It’s the opposite of traditional sample and hold; the
timing varies, but the levels don’t.
