I realy don’t understand what you did in the regedit I have also tried uninstalling all the usb hubs and reinstalled them to no avail. The problem is that resistor coupling instead optoisolator needs both power supply, Midi Source and Midi Interface shares the same ground and this is not happening in cheap devices. I obviously removed this resistor when I decided to put an optocoupler instead. Properties of diode and resistors I will take from Pierre secondary post.

It is self-powered, not powered by USB. We don’t know when or if this item will be back in stock.
Thanks a million, thought I was headed towards a reformat. A2 unknown smd diode and tried 1N diode, same result 5. This video showed me what to do, and I was up and running in 5 minutes!
Can’t find your answer? The problem is not related to MIDI output!
Cheap USB MIDI cable: some self assembly may be required –
Windows 7 IT Pro. Mine is same problem: I am looking at picture of forward post last for now of firehacker and I logllink no bridge on R I also did the regedit trick before. Share your thoughts with other customers.
I tried your solution above but desoldering R11, even though I connected everyhting else as shown, broke the out connection as well.
MIDI in over USB problem
Any suggestions on if and how I could make this work would be great. If you enjoyed this post, please consider leaving a comment or subscribing to the RSS feed. Before you perform any modification on your PCB, I would recommend that you understand the fundamentals of an optocoupler.
It cannot handle the Midi frequency rate. Leave this field empty please: I hope it helps you as well. They assure me that those work for other users of Win7 bit. Hope this helps others. Did you try it with Apple devices?
