modules with different tubes?

[harry]

Aahhh....

Nice try. Probably will not work.

Problem... How do you decide the "waveform" crossing points.  I'm thinking of
a Guitar wave... which is a bastard !  It may cross zero more times than you
like.
Tracking the peaks will not work either.

DDL  pitch shifters do exactly this. If they have very short delays... the
glitches in
the waveform are severe. If you can wait a week... you could make a really long
delay.

You should tape record the whole thing... then edit out every other cycle, then
play
at 1/2 speed...

Or just hire a Psychic to set the unit properly for the "next" note you are
about to
play....
