Thanks. Made me think about 'turning the idea inside out'-- I wonder
if anyone has explored the mangling of LFO control waveforms via phase
shifters? Seems an obvious idea but I don't recall trying it or
reading about it.
Run the stereotypical triangle or sawtooth LFO thru phase shifting, to
scatter the harmonics. The altered modulation time patterns might be
interesting. One could even feed the LFO waveform thru an auto-
sweeping phase shifter so that the LFO wave shape would continually
