Gotta adopt the 1 in, 1 out mantra.
For me, OP-1 out (again), and DN + 12V battery pack in.
Still portable, still got some FM… still 4 tracks even… and I don’t mind trading the FM radio for some conditional trigs and sound locks
But I hear you on the color palette.
Thrilled that those little chiclet track buttons match my portable drum machine (Patterning)
