OK just a thought: does anyone know with certainty if a SD-2 does or does NOT have a CR-2032, CR-2016, BR-2325, or similar internal battery?

Almost ALL these modules, even just small ROMplers/synths (e.g., Alesis Nanosynth and Roland SC-8850) have them. As well as almost every other piece of rack gear and keyboards I own (multi-Fx units, MIDI patch bays, all my ROMplers, keyboards and synths). I change batteries every 5-7 years no matter what in ALL my gear even though they say they will last for 10 or more years and they SHOULD but you never know so I apply the "why wait for disaster" rule - yes it is overkill.

IF, again I say IF, the SD-2 does have a battery it MIGHT be getting too weak, or more likely it is actually DEAD and these "intermittent" SD-2s are caused because by applying power you simply bring back partial functionality when nonvolatile ROM functions and memory load - but zero information that might be maintained in volatile battery backed flash RAM.

Again just a thought
