Running your MIDI Input or Output at 3.3V is fine, and these days many things do. For example, MIDI is a current loop, and says nothing about voltage. Like most cut corners, it can come back to bite you. It's a corner you can cut, and it is against the MIDI spec. They work by using a cap to store the voltage from the actual MIDI signal itself. It was pretty common for 1980's MIDI filters and so on. There have been several "phantom powered" MIDI devices in the past. I hope this is information is helpful to someone! Therefore, it is understandable that they went this, way in my opinion. (Some distribution boxes for that are specifically designed for TRS MIDI might have that already build-in.)Īt this point things get kind of obvious: If the pedal had all the regular MIDI circuitry build in, the same port probably couldn't be used as expression input. If you take it a step further this also means that you shouldn't connect any old MIDI controller directly as there's none of the "safety circuitry" that any MIDI input should have. This ultimately means that the EXP/MIDI jack on Strymon's latest pedals is in fact not a "real" MIDI port but a proprietary multiport that can be adapted to be used with MIDI. Remains the question where they get the 5V for the second side of the 6N138 from? optocoupler, reverse polarity protection diode and resistors. So, as it turns out Strymon's MIDI cable is not just a simple TRS->DIN adaptor but the aforementioned "chunk in the middle" of the cable houses the actual input circuitry for the MIDI connection, i.e. Over on someone has asked the same question when Strymon's EXP->MIDI cable wasn't available in the UK at first and another one got a reply from Strymon that included this photo: Strymon has explicitly stated the MIDI pinout: TIP=Receive, RING=Send/Through, so the SLEEVE must be Ground then. Here's what I have been able to find out regarding those two pedals: However, since the Sunset and Riverside feature the same EXP/MIDI combo jack I figured they must work the same way. Since it's relatively new to the market there's not that much information on the Iridium's MIDI capabilities. Well, I think I have found what I was looking for: It would be awesome if we can find something out together!
Strymon iridium manual manual#
But allegedly some people use the Iridium in conjunction with the Chase Bliss Faves and according to the Iridium's manual you can hook it up to any MIDI controller with a TRS output. So, everything we manage to find out should also apply to the Riverside and Sunset.Īt some point I thought the EXP->MIDI cable must be active and feature some electronics (chunk in the middle of the cable). (That assumes the Iridium can safely provide enough power!)ģrd) Strymon's latest pedals do all feature this connector. Well, of course that would be the easiest way of doing it, but where's the fun? Isn't that why most of us are here?ġst) In my opinion the Iridium itself is pretty expensive already and charging 35€ for an adapter cable is almost Apple-tax-price-territory.Ģnd) Not needing an additional power supply for my DIY MIDI controller seems more than tempting. You might (understandably) ask why I even bother and don't just get Strymon's EXP->MIDI cable. The regular "new" TRS-MIDI is just plain old MIDI with a different connector and still requires one cable for each direction so there must be something more going on here.
Strymon iridium manual plus#
Unlike the original Multiswitch which acts like an expression pedal with different resistors on each footswitch, the Plus model seems to be an actual midi controller.Īnd here's the problem: The one MIDI cable connecting the MultiSwitch Plus and the Iridium does handle bidirectional (!) MIDI as well as power for the footswitch. The specs of Strymon's new MultiSwitch Plus second that in my opinion. The MIDI Manufacturers Association has finally standardized the pinout for MIDI via TRS not too long ago (MMA RP-054), but according to some rumours Strymon didn't follow those specifications. The only problem with doing the same again is the Iridium's TRS-style EXP/MIDI combo jack: I have built a such a "digital footswitch" before for use with my Nemesis Delay and it has been working perfectly ever since. I have finally pulled the trigger and ordered a Strymon Iridium for some silent home practice/recording.Įven though its delivery might take a week or two I find myself already thinking of how I can build a small midi controller to access more presets.
