Midi recording problems with PSR 273

[russtophiles]

Before I explain the problem, here's my equipment setup:

-Yamaha PSR-273 keyboard
-M-audio Midiman Uno USB midi port
-2 Ghz Dell Dimension with 640 MB RAM
-Using Cakewalk Sonar 4

So my problem is this: when I have my setup together and open Cakewalk, whenever I hit a key on the keyboard, while recording or otherwise, as I hit the key it randomly but very frequently produces a very low tone in addition to the tone of the key I hit. I'm using the grand piano voice, but when (and ONLY when) I have cakewalk open it produces this problem (with any voice). I have checked my midi ins and outs to make sure they're correct, and they are. I've turned local mode off on the keyboard and PC mode on, and the midi port is definitely transmitting data because I tried recording and data is coming through fine. I've made sure there's no echo setting turned on in cakewalk. Frankly I'm stumped as to what the problem could be. Does anyone else know?

You've done everything I would think to do, but it may help you get a useful answer if you give a little more info:

The PSR has internal speakers, right? Is this where all the sound is coming from? Do you have PC speakers set up? I guess what I'm getting at, is where the mystery sound is coming from. If its from the keyboard's speakers, something's sending a signal to it. If its Sonar, could it be a softsynth you have open?

Have you checked for driver updates for the M-Audio?

I believe in some software, it can be configured in such a way that it loops the midi data coming in back out to the output. It took me a bit to realize this was what was happening to my setup a while back. Just an idea that may not even apply here, but hopefully it will.

Well I've tried the updated Uno drivers to no avail. Yes, my keyboard does have internal speakers, but I've also used headphones and pc speakers. I also combed through cakewalk to see if I had something on that shouldn't be, and couldn't find anything. I have noticed something else about this though, no matter what key I hit, even if I just briefly tap it, it acts as though I am holding it down as with every other key I press, So if I press a few keys in succession it acts as though I've hit them all at once. On the LED display you can see that pressed keys remain black as if they are still being held, and it happens almost every single time. I can usually tap the key a few times and it'll stop acting like it's being held down, but I really don't get why that would happen...
