@mike @andrew sounds like a software tuning bug :-)

the actual effect would be more like a super slow LFO, or maybe a S&H
triggered from key gate, routed to oscillator pitch with the
attenuator set to 0.001 of a gnat's proboscis?

th note or so you get extra "lushness". I guess you can do something like t=

lator, but it gets lost if you have too many voices. maybe voice # mod 6 :)

 them.
