 A good product March 22, 2008
A good, easy to install and use product for connect your keyboard (midi device) to the computer. I am using a mac and the installation was as simple as possible. It if definitely worth the price and performance. Great for home use, though I am not so sure for professional purposes.
Not what you want IF... February 8, 2008
I bought this device hoping it would work with Cakewalk_9, a midi controller/keyboard, and my laptop. I was really disappointed. The device looks like it's receiving data from the controller but my software just refused to see that there was any midi device attached. I know this company makes a quality product so I'm sure it's my software's fault that it's not working for me. After doing some research it seems that it is probably designed to be used with a different midi recording software package than what I'm trying to use. In short, don't buy it unless you are fairly certain your recording software supports it. Unfortunately I lost my reciept so I'm left with something I can't use.
 Stuck notes ... January 21, 2008

I also have a roland A-37 and the uno randomly misses some notes. I am able to use the UNO if I patch some other device between the A-37 and it. I'm also an electronics expert and I have a pretty good idea of what the problem is: Neither the UNO nor the A-37 fit the electrical MIDI spec well enough to tolerate each other.
I opened the UNO to see how it works. It has an optocoupler that is powered at slightly less than 5 volts. (around 4.4) The uno has a good 5 volt power supply from USB according to my measurements. I am not sure if the designer deliberately biased the optocoupler thru a resistor or what exactly is the reason for the slightly lower power at the 6N138. Whatever the reason is, I suspect it might lower the uno's margin to cope with devices that are marginal.
Meanwhile, the A37 sends a weaker than normal MIDI signal. I have not dug inside it to find out why, but I have measured the current that it is able to drive thru a midi input and it is lower than what most other keyboards can push.
The two devices together don't work, but if another device is inserted (and the uno is patched to the thru) then everything is OK. This is the easiest work around.
 Works Great with BOSS GT-8 Guitar Effects Processor January 2, 2008
I bought the M-AUDIO USB to MIDI Interface cable to connect my Boss GT-8 Guitar Effects processor to my computer in order to download/upload patches. It works flawlessly for my purposes and I've had no problems whatsoever. So, 5 stars from me.
