Just because I have one hidden away in a box, has anyone tried to use a RP12 for effects with a RM100 or any other MTS gear? I've had it for about 15 years and used to use it as a full preamp through my Crate GX900H head and I loved it. Just curious how it would work for effects only in the loop.. I don't remember all it can do, I know it has MIDI functions, but could it switch channels on the RM100?
