Dear Oliver, I have not found a thread which talk about this, so I open a new one.

On the sync side, without a sync cable.
I'd like to have Select+Left decrease the bpm slightly when press in every menu, then go back to normal bpm when release.
Select+Right increase the bpm slightly then to back to normal bpm when release.

Like elektron box.
It will allow to sync more easily with other hardware when you don't want to stick with midi/pulse sync.
It's easier than to go to bpm menu and try to do the same.
