Thisisthe‘stepped’versionofthebasicFILTERalgorithm.TheLFOsignalisarandomizedstep
waveformwhichgivesagroovyandunpredictablesteppingfiltersounds.

TheGlissandoparameterprovidescontroloverthesmoothnessofthesteps.

Therandomnatureofthestepmodulationwaveformmeansthisalgorithmsdoesnothave
asteadytempo;therefore,eventhoughyoucansetthespeedviatap‐tempoormidiclock
youmaynotgetthe‘synced‐tempo’feelinthenormalsense.
