Yes, we have been, but I think I misread the 'Pitch Shift' section on this page:

and mistook that it has a fixed pitch shift value. Upon rereading the
page that seems incorrect on my part.
None the less, we would still require a way to do pitch detection on
the original vocal signal to know how far we are attemtping to shift,
I believe. It's also unclear from this write up how little you can
shift a signal. Does the pitch shift input support shifting down to a
few cents?

I'm sure there's some semantics stuff going on here, but the side
channel I was referring to would have to be on the pitch shifter and
this plugin doesn't have one so there's no way to get it to shift by a
variable amount.
Now I'm confused. Are we still talking about the "AM pitchshifter"
plugin (1433) ? It has a control input port called "Pitch shift" which
determins the amount of shift, you can connect any control rate signal
to that port. Or you could downsample an audio rate signal and connect
that. For realtime modulation it would probably be better to have an
audio rate input port for the shift amount though.
I
don't see that this specific LADSPA plugin has any side channel
input to allow a synth to drive it. Not to say it cannot be done, but
if it's that easy pump out a little demo and let's hear what it sounds
like. Sounds like fun to me.
No side channel needed, the builtin Om note module transforms MIDI to a
frequency signal that you can use to control the pitch shifter. But for
auto tuning you need to know the pitch of the dry sound as well, so I
guess it's not as easy as I thought.
