I have the same problem on my M50-73 that I bought in Feb. I also have a 2nd M50-73 that I bought in March. When the problem occurred on the first one, I swapped the ports card with the 2nd one, thinking the problem would move to the 2nd M50- BUT IT DIDN'T; which means the problem is not with the ...

I have found that there are a few other notes that are affected too. But I have also found sort of a workaround until I can actually take it in and have it repaired (under warranty). My workaround is that I changed the Velocity Curve on the keyboard from 4 (Normal) to 6. That makes the keys much ...

no, my first M50-73 did not do that. its only problem was that after about a month (i do about 15-20 shows a month), the Right output quit (and so did the Right of the headphones jack), so I had to perform in Mono until my "backup" M50 arrived and I took the original one back to the dealer for ...

yes, those 3 notes always play the corresponding note IF i play the note really hard. thing is, i don't usually play that hard, but when I'm actually playing some of my songs and start doing some rhythmical chording up in that area, i DO hear those bad notes triggered. sounds like I'm making ...

Did you find out anything? I really don't want to have to return the keyboard all the way to Georgia, etc. Hoping I can get it repaired in Missoula at the service center, under warranty.

When you strike hard A#4, it also plays D#5 at 127vel, .001 time, but it ALSO played this extra note a second time! When you strike hard G#5, it also plays C5 (which is ...

And when I do it with record on, it actually records those extra notes at 127velocity and .00001 held time.

On my new M50-73, when I strike hard the upper Bb and a few other upper keys, other notes sound ALSO when that note is struck. Any info no this? Thanks.

I just wish someone could post links to and exact bag they know of that I could order. It take so much time trying to find a softcase with wheels that fits the M50-88 best.
