OK. Tried the exp controller (CC#11):
1) drawing in the midi channel in cubase
2) using knob on my Yamaha midi keyboard
still no luck....
kontakt player receives info, showing the keyswitching and the type of playmode, changin bows when I push sustain pedal...
but STILL NO SOUND
You didn't accidentally hit any of the keys C2 - D#2 (MIDI 48 - 51), did you? These will (for reasons known only to the gods and Giorgio&Stefano) silence the instrument intil you hit one of the regular KeySwitches C1 - B1 (MIDI 36 - 47).
