Non-octave VST ?

I'm interested in experimenting with non-Western scales, specifically equal intonation scales (like Harry Partch), and non-octave scales. Is there a VST plugin that will take a midi signal from a normal midi keyboard and assign it a sound (or output frequency) based on an alternative scale? Ideally one could assign a particular fundamental frequency to each midi note to "custom build" new scales. Hope this makes some sense... - JM

perhaps JS:IX/Midi_Variant will do the job or maybe could be a basis for that purpose?

Indeed, this is a feature of the general midi 2 standard. It's been a long time since I used it, so I can't give you details here (though I might look into it again, as it's very interesting). In short, in GM2 devices that support this you can sent sysex data to finetune the pitch of individual notes. I know there were midi files containing the needed data for several tunings floating the net which you would just place at the start of your song. Aah, and I know one vsti supporting several tunings: Pianotec allows you to chose from some tuning methods.

Thanks for the replies - looks like I have some good ideas to work with...

z3ta has a lot of different tunings!

Big Tick's Rhino supports alternate tuning (TUN) files, and the Korg Legacy collection allows alternate tunings, although it is limited to 12-tone scales.
