I find the AI, TP and QC the one’s i’m using all the time… The AI was last on the list but it became indispensable after a while… really glad i got it…
Loading projects at startup, selecting presets in loaded effects and Instruments and from 7.5 it just got even more indispensable for the way it’s now possible to load Trackpresets of saved multi out VST instruments.
Jogging in project, setting monitorlevel e.t.c… shortcuts of the most used functions… well… it’s maybe not easy to choose if you haven’t got a workflow already which you need to enhance, but i found it very hard to choose only one… the “fun” part is i purchased all 8 units slightly after release and payed a whooping $1800 for the bunch ( in Sweden …with some slight discount)
