GarageBand Midi Continuous Controllers?

Where is a LIST of the “Midi continuous controllers” that GarageBand ios and MacOs will accept?

Otherwise Apple Programmers Please Add Code to Both GarageBand versions that will allow for FULL Midi Control for ALL GarageBand Instrument parameters. It’s archaic to use a Mouse to manipulate GarageBand while also playing a Keyboard Controller.

Thanks in advance,
