That looks quite solid, how well does it work in using the QY70 with the data filer.?
On a sidenote, i remembered that my audio interface (an old M-audio ultra fast track 8r) has a midi breakout cable that I need to try and find one of, Presumably it would be something like the midiman since it's a similar era. I'd just need to try and find one that actually work since its a very specific cable.
