Hi, I just got a couple of Ksoloti boards to run from a Bitstream 3x midi controller and I’m wondering whether I need to add resistors to the midi ins / outs I’m thinking of adding (if I don’t go te USB route). Thanks in advance for any pointers!

Hi, if you just got the boards chances are you have revision v0.7, which will make this easy for you. Since v0.7 robust MIDI in and out circuitry is on-board and you will NOT require (nor should you add) any additional resistors to the pins.
220 here, 220 there
everyone safe everywhere
The pins are labeled MI4 and MI5 / MO4 and MO5 because that’s where they go on the traditional DIN jack, pins 4 and 5. MIDI out will additionally connect pin 3 pin 2 (center pin on the DIN jack) to GND and you have the GND pin right there for convenience.
If you use TRS you may have to look up schematics of DIN MIDI VS TRS MIDI (TRS Type A recommended as it has now been definied in the MIDI standard. UNLESS your controller uses Type B, which I remember the Arturias do!)
Wonderful, thanks for clarifying. This seems so brilliantly simple!
I should double check you mean pin 3 on the DIN? as usually it’s pin 2 (the centre pin) for ground.
Thanks again!

Ah, you’re right! That odd pinout always gets me. Pin 2 is the center pin and goes to GND (shield) on the MIDI out connector.
