Seeing that Aria's release is imminent, and that Stradivari and Gofriller have disappeared from the product lineup, it is easy for me to surmise that we are about to see some new Aria-based products.
So if it's not too late, I would like to make two suggestions for future products' user interfaces:
1) I have an E-MU Xboard MIDI controller, which I believe is a fairly popular product. It is capable of supporting an expression pedal and a damper pedal, but not both at the same time. Proper use of Strad requires both at once, which is quite a limitation. Can I suggest that you arrange for future products to be more easily controllable with only one of these pedals?
2) GPO comes tantalizingly close to working with my WX-5 wind controller, but there is a glitch I haven't been able to figure out how to circumvent. Unfortunately, it's a little hard to explain, so I apologize in advance for the length of this explanation.
When I play a note on my wind controller, how hard I blow determines the note's MIDI velocity. Thereafter, every change in my breath pressure registers on MIDI controller number 2.
Kontakt Player 2 uses MIDI controller 2 as a synonym for controller 1, the mod wheel. On the surface, this is good. However, it appears that the loudness change implied by the mod wheel gets superimposed on the loudness implied by the velocity. The effect is that when I play softly, the result sounds much softer than one would expect, and it is impossible to play a note that starts softly and then gets louder.
I believe that the right way to handle this is to allow the loudness implied by CC#2 to supersede the initial velocity. I would be happy to supply a sample MIDI data stream for testing purposes.
