THIS is what I'm looking for!
I already filed a support request for this, they pointed me towards this forum.
It is much needed and I know for many people, this is something they'd love to have.
Currently I'm using LoopBe30 as a workaround, but that has limitations like only being able to address 64 MIDI channels because Notion can only handle 4 external MIDI devices, having 16 channels each.
That gives limitations like this:
With a full orchestral template, you might need more than just the 64 channels available and you can't really create a full orchestral template AND have spare channels for instruments you don't use very often.
Presonus support: Could you please check my current requests on this and about this?
