Hey there,
I don't know exactly what happened (because it was working fine before) but when I try to record Arcade by Output, the notes don't show up in the region. The track only plays the actual key used (example C2) rather than the sounds chosen in Arcade. The only way can you actually hear what you recorded, is not if you press play, but if you press record and hear what you already have. If you press play, there is no sound.
I hope this makes sense!
