- I sympathise Tuomas: I built my own midi interface and I had all degrees of
- midi data reception from 0% to 100%, until I substituted a resistor with a
- potentiometer, and fine tuned the value until the interface worked reliably.
- It seems (based on my experiences at least) that the process is voltage
- critical.
-
- I would suggest you use something like MIDIMON to ascertain exactly what is
- being received. My guess is that your problem lies in the interface hardware.
- I'm not sure how accessible the electronics are, but the next step for me
- would be to use a cheap logic probe to see where the signal breaks down, and
- maybe tweak the circuit slightly.
-
- Email me if I can help further,
