Hi Tony.

I've added some additional thoughts below given the information you've added.

"Space bar" and "Press any MIDI or QWERTY key" are two different functions in BIAB (see #1 and #2 on the image below). Using your foot-switch that activates the spacebar is not the same as pressing a qwerty key.

I am not sure what you mean by "see if a MIDI key from your Roland will start playback" The Roland synth has no keys and I can always start playback using my computer keyboard. It's just that I always get an access violation if I keep playing the piano while it is connected to the computer and I never get this if I simply stop playing the piano.

I didn't realise that the SD-50 was a sound module. I thought it was a Roland keyboard synth.

Does this mean that you have a keyboard connected to BIAB and that BIAB is set to play its MIDI sounds from the Roland SD-50, which means that the keyboard you have connected also accesses the SD-50's sounds? Is the Focusrite mentioned in your original post the device that allows you to connect to your speakers. Also, am I correctly interpreting your original post to mean that you have a separate USB connection for your MIDI keyboard?

If I am correct, are your BIAB MIDI Driver settings as follows?....

(a) Input device = MIDI keyboard through the USB MIDI device

(b) Output device = Roland SD-50 Sound Module (maybe as a VST synth)
