The most obvious use for IC Pro is as a remote when tracking away from one’s DAW.
There are better MIDI controllers (ie, requests for a keyboard, etc).
It will never match the editing one can do on a computer screen (requests for waveform edit capabilities, etc)
But as a remote? Sweet.
Channel control would allow tweaking sends, EQ, etc. when tracking (as stated).
Locking faders would allow easy tweaks to mix and levels when at the mic - in my case Control Room (my personal headphones come off CR Monitor 4).
