For similar reasons, selection of any track via MIDI is not possible and will not be for some time.
4.2.x will have a Select Next Track MIDI command that works like the Next Track button on the Aeros, but selecting any track at any time is not something that we can allow at this time without causing other bugs. 4.2.0 is already out but has some known bugs and will be replaced soon with a new beta.
Thank you for your questions, stay tuned!
