If you’re dead set on single cycles, you could make a set of phrases that each trigger only one note (each note being assigned a unique single cycle waveform) then use a similar method of phrase control automation to be able to cycle through waveforms with a macro like the grain scrubber does. It would be a little work making the phrases, but you’d only have to do it once and then you could use it for any set of waveforms you’d like
