← Line 6 Pedal Board: USB interface, with Arduino
I started one of my projects using the cheap Chinese MIDI to USB cables (silver wire, black oval housing, LEDs, red-green-amber. Just a verbal description. the problem is a bunch of junck parts put on market with many errors in`programming includding units not using true midi standards, limited channels etc.
I am a low volume producer of a midi device using 2 of the cables per system there for I am looking for a device simular to your sketch. I have need 0f sending a digital signal to an optical coupler via twisted pair MIDI standard current loop through custom circuit (your device) then the processed serial data to USB standards to my linux computer. I can handle the wiring but need the MIDI chip to signal the linux system thst this is a MIDI interface requirement plus a common name designator that does not change.
Hoping this info gives you the background of my purchasing problem of a fully functioning MIDI to USB cable/convertor.
Thanks for any assistance you can provide,
I’ve had varying success with cheap USB-Midi adapters. Sometimes they work just fine… But there’s a reason m-audio sells the Uno for ~30$!
I now use pjrc.com’s Teensy http://www.pjrc.com/store/teensypp.html when I need clean USB connections. They end up being the same price as an arduino + adapter. See this post for an example: http://practicalusage.com/?p=947
I don’t understand why you need two cables per system. Can you explain?
