Allow 8 external midi controller knobs to be mapped as 'macros' such that the first 8 'in focus' knobs in a track can be controlled from the mapped midi device. Similar to cc midi mapping in DAWs such as Ableton. 'In focus' to mean the device (instrument/effect) opened in front of the track, or if not open, add the concept of focus so a track device (trigger, effect, oscillator etc) can be selected as such.
