Building a Note Controller with Codebox

How to use codebox in conjunction with "@voicecontrol user", as well as some useful code snippets.

The @voicecontrol user setting for rnbo subpatchers allows you to craft specific MIDI note handling and voice management behaviour in the way you choose by creating your own note controller to handle the incoming notes and assign voices yourself.

Codebox is especially useful for this - it gives you complete control over the MIDI stream before entering your subpatcher. In this article series we’ll cover how to implement your own note controllers using codebox for some common synthesizer polyphony settings.
