Up until now I’ve only had Strymon and Chase Bliss using 1/4" TS/TRS for MIDI. (tip=data and sleeve=ground for Strymon; ring=data and sleeve=ground for Chase Bliss)
I just got a Boss EQ-200, and tested setting it up with the MC-3 and MIDI Box to use the MIDI Standard (Ring+) configuration.
All is well, but it does raise one question. What is the risk on stage if someone is repatching cables while powered up? Does Ring+ pose any risk to the MC-3 or MIDI Box if they are powered at the same time the plug is being exposed? (ie: accidentally bridging any of the TRS connections).
Seems like MIDI DIN posed little risk due it’s physical design … I’m not so sure about TRS.
In the MIDI standard, the circuitry in the MIDI receiver is completely isolated from the sender, so if you are indeed connecting it to a MIDI port, it will pose to risk at all.
If you plug it into a non-MIDI port then that’s a different story.
I also just got a Boss EQ-200. I haven’t had time to set it up yet, but I was thinking that I could just connect a standard 1/4" TRS (on the Boss) to an Omniport on my MC8 via a standard 1/8" to 1/4" TRS cable. Is there any reason why this won’t work?
The MIDI I/O on the Boss is already 1/8" female jack. It’s the Exp/Ctrl port that is 1/4", I don’t use that. Stick with TRS 1/8" on both ends of the cable with MIDI I/O … easy peasy.
If you ever do run into a scenario where you need 1/4" to 1/8" TRS male jacks, there is no problem adapting it as long as the wiring is still compatible for what you need. Theoretically, had the Boss used a 1/4" MIDI, you would have been fine with any standard form of adapting the TRS cable to match.
