Thanks Bill,
however, that only works using MIDI messages? What we really want is the communication to be 2-way, so that the controller gets updated when a parameter changed (from the GUI or due to automation). Is that possible?
Also, we want to do this without the user to have any settings. It should "just work". (like you use controllers in ProTools, where the developer can map the parameters to the different types of controllers).
So, as an example, let's say I have an eq, and a controller with 8 rotaries and 8 switches per page.
So, page 1:
switch 1: band 1 on/off
rotary 1: band 1 freq
rotary 2: band 1 gain
rotary 3: gand 1 q
switch 5: band 2 on/off
rotary 5: band 2 freq
rotary 6: band 2 gain
rotary 7: gand 2 q
page 2:
switch 1: band 3 on/off
rotary 1: band 3 freq
rotary 2: band 3 gain
rotary 3: gand 3 q
etc. etc.
I hope this is clearer now.
Greets,

You could provide a hot-map type facility in your UI using the audio unit properties that are defined for this (see <AudioUnit/AudioUnitProperties.h> (kAudioUnitProperty_AllParameterMIDIMappings, etc)
