I installed omnisphere 2 in cubase le and tried to play cords with the Montage and only 2 voices are heard instead of all the voices that I play. With a other simple usb keyboard that I tried everything works fine, so can anyone help me with this problem.
On what MIDI channel are you transmitting?
On what channel do you want to transmit on?
It is not clear what you want to happen (only what is happening is not what you expected).
Are you trying to play just Omnisphere, just Montage or both layered/split, this is not clear...
Montage is 'complex' MIDI keyboard (sorry)
MIDI channel 1 and want to play only Omnisphere on that moment
