Quantizer

A 2-channel quantizer to round v/oct pitch signals to a musical scale.

The two channels can be totally independent or linked together. Each channel has adjustable transposition, delay, and portamento, with sample-and-hold, track-and-hold, or continuous quantization. Quantization scales can be set note-by-note, and also saved and recalled from persistent storage.
