[timothy]

I've been using one of these for a little over a year. Within the last couple of months, the right channel has developed some sort of problem that has only gotten worse over time. It's now so bad that the right channels basicly useless. I plan to keep the device around simply because its my only midi device, but beware: if you start to notice noise developing and its still covered by the 1 year warranty, get it serviced right away as it may get worse.
