A new question, if I may: How does automation of instrument positions work? Let's say I want to have an instrument closer for a solo section?
You can't automate movements of MIR Icons, because this leads to small, but audible interruptions and clicks in the audio signal. This is due to the pre-rendering of the case-dependent IRs which takes places as soon as you put an Icon into a chosen spot.
For a solo part I would create a seperate instance (much like the MIRx presets are organized).
