Hi there,
I’m not sure if I can’t search or there is no such subject.
I have Cubase 5 and I’ve already managed to connect my dr-880 as a midi device.
But, (there’s always but 
) I have no idea how can I play midi via my boss.
When I open my addictive drums and hit some of the pads on boss it gives sound from addictive, but when I create new midi track and add some notes there is no sound from my boss. (I’ve set the same midi channels on both devices)
If there is some way, I can record or import to my boss, midi track I’ve made in cubase, please help me.
I’m sorry for language mistakes, my foreign language is Polish.
