RE: Doubled midi notes- Problem Solved

[gw sound]

I just wanted to get back in touch, as others have possibly had the same problem. Mine was with the M-Audio Keystation Pro 88. I was having doubled midi notes sometimes- tiny second notes hiding behind the original. I spoke to M-Audio today and figured out the problem. I was using the USB power cable that comes with the keyboard, and using a midi cable into my midi i/o. This seemed logical, since M-Audio doesn't supply a wall wart power supply. What I didn't know is that the keyboard was sending midi information through the USB cable as well as the midi cable, causing the problem. I bought the wall wart power supply and pulled the USB supply. Since then I have tested recording midi 5 or 6 times and can't reproduce ONE doubled note. This may sound small to many, especially to those who haven't had this problem, but this has been killing a handful of us. So, even if you aren't using the M-Audio keyboard, if you have a setup like mine, you can probably rectify your problem by using a wall wart. It seems that there should be a giant warning in the instruction booklet about this, especially since the USB cable is the only possible power that comes with the keyboard.
Hopefully this has helped someone else-
Thanks again for earlier replies

Why use a midi cable?

I'm not using a midi cable on mine and it works great.

I'm glad it solved your issue but I've been using the wall wart since day one and have never plugged it in via USB. I just run MIDI out into a Digi MIDI i/o. The same goes for my Roland SPD-20 where I am experiencing the exact same issue. I think it has something to do with the sensitivity of the triggers. It's a pain but I work around it.

I'm sorry that is't the problem for you. I thought some of the others complaining about the doubled notes might have been doing what I was doing. As far as "why use a midi cable?", the gentleman I spoke with at M-Audio told me that with my setup the midi cable and power supply is the best way to go- so I took his advice.
