Hi Andi,
I have checked and double checked updates etc.
using sibelius 8.6
vienna ensemble pro server 6.0.16502
reinstalled instruments
they are loaded instance in the ensemble pro window and look ready to go, but the piano keys will not trigger a sound, which in the past has meant something is wrong with the connection between the two programs. In sibelius, configuration is Vienna Ensemble Pro, with the sound set Strings. (using solo strings).
imac 4.2 ghz intel core i7
thanks
john
