Im not dead sure, but I think that version was faulty. You probably want to use a 6n137 version wich is a slightly different circuit.
Mail me at: @.*** asking me for the correct circuit. I will search it in my computer

Hello! I've been slowly putting my Opera Rotas Rev 0.95 together these past few days. I was missing some components, so I had to order them on ebay. I was able to figure almost all of them out, but I got tripped up trying to install U4, which is listed in the schematic as a 4N35 chip? But my socket on the board has 8 slots, and the 4n35 has 6 legs. Is that the wrong chip? Or does it only use 6 of the socket slots?

Ok thanks for the info! also I think github hid your email. I think you can attach files to these comments?
I think I hide it myself for the spam bots :)
Here you have the working midi part
You will probably want to cut the trace of the midi in that circuit and solder this midi out to the corresponding pin on the bluepill

I'm not sure I follow? Is the 6n137 the correct chip? or is it the 4n35? Also I'm not sure which traces and pins those are?
Hi! The correct is the 6n137

Hey so all my components finally came in, I soldered them in place and powered it on! But only one button seems to work (sw15). Do you have any suggestions for troubleshooting?
If its a preseldered PCB, reflow the bluepill. If it´s an older one, reflow the 4053 of the buttons
Glad to hear it!
Check the github, I have responded there. I would reflow the bluepill and try again

Its the presoldered or the the older pcb? If its the older, try to reflow the the 4053 muktiplexor that is connected to the buttons

The pcb was not presoldered. Also what component is the 4035? I don't see that on the schematic. There's the 4n35, but that was replaced with the 6n137
The 4n35 never worked. The 6n137 works perfect. The chip that you have to reflow too is the CD4053. It´s the multiplexor that connects all the buttons with the bluepill
