I am starting to use the Stradivari. Reading the manual I see that the use is based upon keyboard info sent. This is what I never do, I never play the Strad from any keyboard, not now and not in the future.
So that leaves the Midi input as a file, ready for a sequencer.
I also found out that CC#1 is for modulation, CC#11 is for expression and CC#64 is for sustain. I can draw that in Sonar.
But in KP1 the volume has to be done with CC#1 and the attack comes from the velocity. Using KP2 and Strad where does the volume come from? Which controller (#) or... I certainly missed something, but what.
Raymond - today my personal velocity is at a very low level.......
And CC#64 is not really Sustain, at least not in a pianistic sense of the word. It does prolong notes, but only until the next note is played. It is used primarily to create a smooth bow change on the same note, when played live.
Also don't forget Aftertouch & CC#67. They both control vibrato speed.
