As users, what do you need most ?
Before your comments, let me expose quickly my idea. (And again, sorry for my poor English.)
Since few years we have now wonderful, marvelous libraries.
The weakest point, in my humble opinion, is productivity.
The tool to use them effectively doesn’t exist for me. Ergonomics is everything for a pro use.
My point is this : a lot of actual limitations is due to the fact that players and sequencers are separated softs.
And this separation is purely artificial.
Imagine a single soft :
First, no more routing (midi or audio), every thing is already set.
No more track naming.
The ability to ‘see ahead’ to trigger the right sample after recording (a kind of an ‘off-line speed detection’, much more efficient than a real-time can be).
No more key switches.
The ability to trigger any sample on any note very quickly by, for example, a contextual menu in the midi editor...
A possible ‘real playback’ at the cursor (instead of the actual and unusable ‘chase note’).
It’s not a so big deal. It just have to be Rewire.
I also think that, even if I was a multiple DAWs fan before, I realized quickly that this approach is not productive at all for many reasons. For a pure sampling approach, for let’s say Symphonic music, a single DAW is conceivable if the whole library was permanently buffered on an actual Solid State Disk. One DAW in use, and no more loading time could be also a big productivity improvement. But it’s another story...
(As you can see, it’s a kind of ‘I had a dream’ topic... let you go...)
