I don't quite follow. Are you wanting to add an AUX switch to EXP 1 or EXP 2, and on that AUX set up a momentary switch?
Also, what controller do you have (MK I or MK II). On MK II it would be pretty easy to set up a momentary action. You would have your "on" message send on press down, and your "off" message send on release. So if you wanted to momentarily engage a pedal while the switch is held down, and bypass when released, that's what you would do.
If that's not what you meant, could you provide a little more detail?
It’s a MC Mk1 - yes I want to connect an M-Audio (piano style) momentary footswitch...its for a vocal harmony unit, so when I press down and hold the harmony is engaged and then disengages when i release it.
I’m not sure if you can connect just a single switch. Possibly, and then the TRS would just ignore the other two commands. So if you could connect a single switch, then...
You’ll want to set up a Toggle Hold message, either a PC Toggle Hold or CC Toggle Hold, depending on how you’re using your device. The Toggle Hold message is effectively a momentary switch - does one thing when pressed down and a second thing when released.
Looking at the M Audio sustain pedal, it looks like it has a TS cable instead of a TRS. That might cause issues (not damaging, but the MC6 might not send messages if it’s connected). Or it might not and it’ll work as mentioned above, where the R (ring) is ignored. Connect and find out. But long story short, see above for how to set up the momentary command!
The jack is a ts should I solder on a TRS? When I connect a pedal to the EX 1 or 2 the only choice I’m given is ‘expression’ nothing else? So I am unable to select anything for the pedal?
You need to set up Exp1 and Exp2 during global setup. Your options will be Expression or Aux. You’ll want to set one of the ports to be Aux. I’m not sure if you need to make a TRS cable. I’d try using the TS cable as is and see if it works. The AUX is set up so that tip = one preset, ring = a second preset and tip + ring = a third. So I want to say the ring and tip+ring presets will be ignored. But maybe James can chime in!
Tries both Aux and Expression both do not work, have tried with TR and TRS in Aux what ever is plugged into the Ex input changes it to K and none of the other buttons can be accessed until it is unplugged.
Folks beware if you are thinking about buying an MC6 you can not use momentary switches and the support is not good.
You can absolutely use momentary switches, but it sounds like not a sustain pedal. However you can set up a switch on the MC6 to do exactly what you want, or use a proper 3 or 6 button AUX controller. Why can’t you use one of the switches rather than a sustain pedal?
I have the mkII now but had the original and used momentary commands all the time. And I find their support to be very good. I don’t think they are super active on the forums but respond to emails fairly quickly (might take a day or two since they are in Singapore). And the online manuals are helpful too. If you ever have an issue you can email email@example.com or firstname.lastname@example.org . They work fast to resolve any issues.
So I politely ask that folks ignore the advice about support and momentary switches.
I did set up a switch on the MC6 (Mk1) but it’s too tall to use as a momentary switch. The pedal i have tried is a sustain pedal... I tried to set the NC6 to Aux and that did not work - the MC6 goes to J or K and freezes until i unplug the suns pedal. The only other choice is Expression mode which does not work as a momentary switch.... The MC6 does not appear to work with momentary pedals 😕 no help or response from emails
Yeah, I think the freezing is because the MC6 is expecting two other connections (a ring and a tip + ring) and glitches without those connections. That was my initial speculation.
Would an external 3 button Aux switch be shorter to use? Something like this:
That is, are you saying the MC6 sits too high up to be used as a momentary switch? If so, I think one of those 3 button controllers would sit just as low as a sustain pedal, and then you'd have two additional buttons you could program.
Or if you really wanted to use the sustain pedal, I bet I could make you a custom AUX switch. It would look like the one above, but have two footswitches, a TRS jack, and a TS jack. You would plug the sustain pedal into the TS jack, and wire that up like you would a third footswitch. I am almost certain that would work, so long as the sustain pedal is a momentary, normally open type switch. And I could probably fit that into a 1590a enclosure, so it wouldn't be too much in the way.
