Random LFO
I put this together after a suggestion from @NotBasho. It’s an LFO with a variable waveform and amplitude. Either can be set to vary randomly for each cycle of the LFO. The waveforms are:
sine
triangle
ramp
reverse ramp
square
All waveforms are phase aligned and begin on the rising part of the cycle. The wave shape is synced and only switches at the beginning of each cycle to prevent abrupt changes. The output is unipolar from 0-1.
The amplitude can be varied continuously using the knob. When set to random, the output will be randomly scaled for each cycle, with a maximum at the knob value and a minimum of 0.
Frequency range is 0-20Hz

This is so cool! I can’t wait to mess around with this, haha. Thanks for sharing!
