Rec+Track # Arms the track but requires two hands, one quick button press is better
Add track arm to the External Control Device MIDI Map so that it can be enabled from an external controller, which would be the most effective way to arm a track when 'in flow' and working from an external midi controller. As a general principle, the more functional controls that can be made available from external devices, the better to improve flexibility and flow in use of the Reliq as the central hub of the studio.
