I am connecting my Virus TI Keyboard via MIDI cables to my other equipment.
I noticed an apparent lack of aftertouch MIDI data when in multi mode.
I then determined the following using a MIDI data monitor:
When in single mode the Virus transmits aftertouch data correctly.
When in multi mode, the Virus only transmits aftertouch values of zero.
Edit:
To exhibit this behaviour, the Config | Keyboard (1/5) | Mode setting must be set to multi-channel.
Many thanks
