For me - ABLETON SESSION PAGE style Clip launch and pattern composition mode would be the game changer.
This is only because I’ve discovered that both Ableton and MASCHINE are a no-go when it comes to using them at all to access big libraries hosted in Vienna Ensemble Pro. Hence I’m really hoop that finally - like MOTU has with DP recently - Steinberg add Ableton Session style options in Cubase.
I’m coming to Cubase 10 really for the “first time” in anger since Atari days - with view to doing big template and orchestral stuff in the future. VEP and all that. I’m currently just really trying to get everything sorted, a workflow and template sorted and settled plus a whole load of ergonomic and tech issues sorted before I can settle down.
Trouble is - I’ve come from the Ableton world. - and frankly miss Ableton a lot. Recently I’ve been exploring and investigating how much orchestral stuff - recently using the Spitfire BBC SO library - can also be done where needed - in Ableton and MASCHINE - AS WELL as in Cubase of course. Frankly not a lot.
Clearly I like the pattern way of composing. I’m happy to do “linear” with cubase too.
But getting back to the OP - I’ve found out that basically for large orchestral libraries ( or not so large in my case ) that one hosts in Vienna Ensemble Pro - its a NO GO to attempt to access them from Ableton or MASCHINE. That is - unless one cuts down there VEP instances into separate ones with no more than 16 instruments or channels per VEP instance. This is of course so one lies within the 1 MIDI port and 16 MIDI Channel restrictions one is forced to use in Ableton or MASCHINE since neither of these otherwise useful production tools allow ( far as I can tell ) any MID port other than 1 to be used.
So a Live style SESSION page mode for Cubase would be a game changer feature for me.
