Yoshimi User Manual ~ LFOs

## LFOs

We only show the amplitude LFO as all of these have identical controls.

- Freq. The frequency of the oscillator
- Depth The amplitude variation applied
- Start (phase) The LFO position when the note starts. This is locked to the incoming MIDI clock if both BPM mode and Continuous is set
- Delay Time delay before the LFO comes in to effect
- Rand Amp. (random amplitude) Degree of 'humanising' variation of LFO amplitude
- Rand Freq. (random frequency) Degree of 'humanising' variation of LFO frequency. Disabled if BPM mode set.
- Str. (stretch) Anticlockwise LFO is faster on lower pitch notes and vice-versa. If BPM is set the control does nothing
- BPM When checked locks the delay control to the incoming MIDI clock
- Cont (continuous) Normally the LFO starts and stops with the notes, but when checked the LFO is free running independent of whether any notes are sounding, unless BPM mode is set
- Type The shape of the LFO waveform

Where LFOs are used in the frequency panels, it's advisable to be cautious with the depth control, especially when using the more extreme LFO shapes e.g. square wave (Squr). These can become unstable at high depth settings.
