Yoshimi User Manual ~ Random Walk

## Random Walk

The sound from PadSynth can be soft and scintillating, yet after playing some time, you will notice recurring patterns. This is due to the fixed wavetables, which are built once and then looped over and over again, for performance reasons. However — each new set of wavetables will re-shuffle the phase information randomly, and so we'll get a completely new patterning, whenever building all wavetables from scratch. This is an expensive operation, but fortunately it suffices to do it occasionally.
Retrigger The sample time before recomputing, from 200ms to 60sec.
Zero (left) disables retriggering completely.
At the above times the settings of the following controls will be read. They each randomly change one characteristic of the wavetable by a variable amount between 0 (off) and 599%

Detune: slightly change the note pitch
Filter freq: nominal frequency of the filter, rsp. vowel position of the formant filter
Bandwidth: spread of the harmonic profile
Line Width: width of a single peak within the profile
Profile Stretch: stretch out and modulate

Note
This extension to PadSynth is still experimental, and the precise control behaviour and ranges may change following experience and feedback from users.
