What is CC 0?

[d.healey]

I just noticed that with the CC modulator we can select 0 as the CC number? Is this used for anything in the MIDI standard or can we use this as a generic controller, using the default value knob to control the amount?

@d-healey Aren't those things sometimes vendor-specific?

CC 0 is classically used for Bank Select
