Does an i2C expansion yield more audio inputs and outputs?

I’m a little unclear on i2C expander options. Does adding a Teletype yield more Audio ins and outs or does it just yield more CV ins and outs?

Technically, none of those.

It adds gate/trigger inputs and low bandwidth CV inputs with optional slew, kind of like MIDI.

But it does effectively lead to more audio ins, because now you can use those signal inputs, which were previously needed for control signals, for audio.

Definitely no more audio outs though!
