Sibelius Ultimate, Windows 10, HP Pavilion 17 Laptop, iRiG Pro USB keyboard, MIDIMAN Uno USB/MIDI Interface to Korg X5DR MIDI Module
The iRiG Pro shows up as the input device, and Sibelius will receive notes from it, albeit with sufficient latency that I cannot use it in Live Playback, because the only available output that is listed is Microsoft GS Wavetable (software) synth.
When I go to the Configuration Dialog, I cannot deactivate the Microsoft GS Wavetable output. The MIDIMAN Uno USB/MIDI Interface is one that shows in the output list in the left-hand pane, but the entire list is greyed out. In James Humberstone's book Sibelius 7 Music Notation Essentials, he states (p.386) that one must deactivate active outputs to activate a new one, however both the activate and deactivate buttons are greyed out, as are all the listed output devices.
Please help,
