I play at work in a fairly small office and the big keystudio is kind of hard to get around, which is another reason why I bought the Behringer. This could also be do to the fact that I accidentally knocked mine off of a table, it landed pretty hard broke the volume slider. Its only happened when I'm just messing around trying to come up with something.

I havent had it happen while trying to record. And it usually only happens when I play a little harder than I should and seems to happen when I'm trying to play something fast. Which those are the 2 I use for the most part. this has only happened with Cakewalk Sound Center and Z3ta+ 2 though. its not stuck down or anything at least that I can visibly see but the synth will just keep playing the note til I hit the key again.

I've had maybe 3 instances where a key gets stuck playing. You mentioned 'stuck notes' I have had an issue with something like this on the Keystudio. And just using the USB connection works great for what I can do. Takes me a lot of playing around with it to find anything worth recording though. I know enough at the moment to find a melody in the same key as what I play on guitar. As I'm really no good with piano/keyboard. Well I'm honestly not a good person to ask. Any way, I just use the midi in on the Saffire with ASIO and it's good to go. I have to say since I moved up to the i7 processor, I tested it a few times and the problem doesn't seem as bad but still is there. I was wondering if you had experienced this with your M-Audio rig. It is fine for slower passages but if you ever do any gliss passages, for example wiping your hand up the keyboard for that Hammond organ gliss, the straight in USB signal gets recorded as gobbled-gook with dropped and stuck notes. I have found that running the Keystation into the midi in on both my Saffire and my Roland Studio-Captures records flawlessly while using the USB on the Keystation directly in to the computer causes dropped notes. I'm running the Toshiba laptop with the Saffire 6 USB and the M-Audio Keystation 88 Pro. Sidroe CM, My portable composing rig is almost exactly what you have. Thank you for your help and I will let you know as soon as I try your tests. I will also try the Behringer ASIO drivers as well. I've tried it with both ASIO4ALL and WASAPI. I'll have to pick one up next pay day kind of on the broke side of things atm. Well I dont have the right cables for it. (Be prepared to uninstall and put you Saffire6 only ASIO drivers back). Download the Behringer ASIO drivers for the the UMX250 and see how that plays with your Saffire6. (WASAPI or ASIO4ALL may be low enough latency to remain a realistic final solution if it plays well with both devices). If you've got the right cable test it through your Saffire6 (I see it only has the 2 inputs you might not want to sacrifice). ShellstaX So you are likely running ASIO drivers for your Saffire6? Test 1.
