What I like about this concept is that very concise code provides for full control of a note's pitch. You can play it in any scale. You synth supports microtuning. You can 'bend' a specific note while it's playing. You can play two voices in unison. These features takes pages of code in my MIDI synths. Microtuning is seldom supported by soft-synths. With your model it's difficult NOT supporting it. Jeff McClintock
