Midi keyboard connection wiring #116

Closed ramainen closed 2 months ago

ramainen commented 3 months ago

Hi! How you connect your midi keyboard to board? I have one esp 32 audio kit board, but I did not understand, which board pin must be connected with midi pin.

also, in this video https://youtu.be/_iwpOnLWirU?t=574 I see something orange, midi-like. Is this mean I can connect midi to audio-in jack?...

Thank you

6N138 maybe?...

marcel-licence commented 3 months ago

Hi, yes, a little circuit is required to connect your MIDI device. The most recommended part is this one: https://github.com/marcel-licence/ML_SynthTools/blob/platformIO/extras/MIDI_IN_H11L1.png You will find little schematics for the 6N138 too. The orange cable is a DIN 5pin to 3.5mm jack adapter for easier connection with the circuit. You can use a DIN 5pin socket too or connect the two cables to your circuit directly. Hope this helps

My midi cable has 5 and 4 pins connected to cable. 3, 2 and 1 connected to nothing. But in chematics https://github.com/marcel-licence/ML_SynthTools/blob/platformIO/extras/MIDI_IN_H11L1.png wires are connected to 3 and 4 image image

And in another sources also using 4 and 5: https://electronics.stackexchange.com/questions/400080/how-do-i-use-h11l1-correctly-to-receive-midi and https://forum.arduino.cc/t/midi-3-3v-circuit/698917

Maybe mistake there?

I see, must be 4 and 5.

marcel-licence commented 2 months ago

Yes, thank you for your feedback. It was a mistake. I updated the schematic today. I didn't recognized the wrong connection. Please let me know if this issue is solved now

Totally solved, esp32_basic_synth works well, connected 4 and 5
