RE: Voice to MIDI thru voc proc and guitar synth?

[Jeff Larson <jeff.larson@sailpoint.com>]

I'm not exactly sure what you're looking for.  If you want to sing a
note and have that note converted to a MIDI note to trigger a synth
then there are lots of software options and a few hardware options.
Searching on "voice to midi" came up with these:

And as Chris mentioned there is the IVL Pitchrider which you may be
able to find on eBay.

But because you mention vocoding it sounds like you may not want
voice-to-note conversion.  If you want pitch converted into a stream
of MIDI continuous controller values to control things like the
volume, modulation, or filter of a synth then I'm not aware of any
hardware to do that, but there is probably software somewhere.

I haven't used any of these but like a guitar synth I suspect the main
limitation is that only note and volume is converted.  Timbre changes
are not converted so you can't for example have your mouth resonance
control a synth filter to get that "talk box" effect.
