Ezra,

You are probably right - the jitter is most likely founded in the midi
source.

I just want to point out that there exist very sophisticated MIDI
controllers such as the Continuum Fingerboard (www.Hakenaudio.com)
that, utilizing typical midi to cv controllers, can output smooth
glissandos via midi (note and pitchbend information) up to 36
semitones (using an Encore Expressionist midi to cv converter).
