I have a bunch of synths from Native Instruments, including Massive and Absynth. I currently control them using a midi keyboard and a midi controller, but I'd prefer to control them using my voice. For example, I wish to control the pitch and loudness of a soundscaped like sound from Absynth using my voice, where slight changes in pitch in my voice will be reflected in the pitch of the Absynth sound.
Additionally, say I have an idea for a string section for a piece of music I'm working on. I would like to be able to hum the section into a mic and in turn have it control a string instrument synth.
Perhaps its possible to convert voice to midi and feed the synth with midi, using the pitch bend to represent subtle changes in pitch. Perhaps Open Sound Control can be used.
What software is available which might help me to achieve voice control?
