Max44, many thanks for that cc# info. I’ve been pondering what to do since I got the synergy duals running in mine. Sounds like I just need to get a behringer or Roland midi foot controller now.
Holy Guacamole! I have a 1250 and plenty of Dual modules. Never even thought to try them in the 1250. Thanks for that intel.

Trying to get MIDI switching working properly on this thing is giving me fits!

More likely I just don't understand how to configure it, being a MIDI novice and all that. PC messages were easy and flawless with my other amps. This CC thing has really got me puzzled though.

I'm starting to wonder if maybe my controller isn't capable of properly switching, even though it says it's capable of sending CC messages. It works, but it's erratic at best.

I'm curious how many people here have 1250's and what controller you're using for MIDI switching?

I’m no help Dirk, but when and where did you find a 1250?

You are truly into the rabbit hole now :)

Rob hooked me up last week. Not entirely sure this monstrosity is for me though. I'm still exploring whether or not it will do what I need. If I can get the switching figured out I think it will make a great studio amp. Otherwise maybe I'll just stick with the other MTS stuff I have and let someone else have a go...

I could get by with the manual cycling through for what my intended use is, but I'd much rather have it foot switchable. My Fractal doesn't seem to want to operate it correctly though so I'm wondering if it's a problem with the way it's sending CCs. Might pick up another controller and see if that fixes my issues.

When I go, I go all out LOL

Has anyone here besides Max gotten MIDI switching working properly on the RM1250?

I'm about ready to pay someone to help me get this thing far the Fractal forum has not been very helpful.

Ok, now I’m even more confused by what I’ve done. I actually have it working and switching properly with my FX8 but I’m forced to use the two MIDI blocks and it’s responding to program changes (0-23) rather than control change messages?

Can anyone here help and provide some words of MIDI wisdom? If nothing else I’d love to know why it works this way because it’s baffling me. I’ve read both sets of manuals repeatedly and googled for the last week and I’m still in the dark. Only blind luck has gotten me this far...

Necro bump.

Finally got me a decent midi controller and am trying to get my 1250 talking to it. No luck, but I do have some specific Randall midi questions that I don’t know the answer too. I imagine if anybody has their rm4 or rm100 working with a midi controller might be able to help me with.

Any forum members still checking in that might could help. I am hesitant to dive into it on the Facebook page as things get off track pretty quickly there.

Many thanks.

I’ll answer my own question in case anyone ever looks at this forum for info.

Morningstar MC8. Seems the 1250 only talks in midi channel one although there is a red dip switch like an Egnater M4 behind the left middle slots (behind the modules). Mine didn’t change anything.

Randall’s documentation speaks of cc numbers, mine only recognizes program changes. Also, the program numbers vary depending the mix of single and duals within a 2x2 matrix of modules. Or to say, it is set in in three blocks of four slots. So if I decide to switch out one of my dual modules with a single or vice verse, all of the Program numbers change for that block.

Anyways, I can randomly access all dual channels of my 12 modules now.

Last word of warning, something like an MC8 can use phantom power, but draws 200 mA. I don’t know what the internal midi fuses are sized, so I used a 5 pin cable and powered it from my pedal board power supply. Perhaps I am worrying too much, but I don’t think the 1250s are that easy to get apart.
