I had the same problem and it turned out to be a cpu board problem.

Hmmm. To me these two seem to contradict. So the same notes that are problematic and shift with the oscillator octave, work fine when driven from another keyboard via MIDI? Sorry, I made a mistake(bad english)! I connected the keyboard to my pc via midi and played it and on the vst all notes of the ...

Thank you synthjoe for the reply. Through MIDI the keyboard is fine and the battery change didn't make any difference, so I suspect it has a corrupt waveform ROM as you said. The problem exists on specific notes in each waveform.If I change the octave of the oscillator the problem shifts to the ...

Hi! A friend gave me his 01/w to play around and told me that it needed battery replacement. I turned it on and reloaded factory sounds because all data had been erased. The problem is that many of the programs(not all) sound funny.Some of them are distorted, others sound like space sounds!The ...

I think there is no such option in global menu.
You can try to disconnect the joystick if you are familiar with opening the instrument.It isn't very difficult!I don't think there will be a problem and you can always connect it again in case you see one!
If you do it, keep us informed please.

I'm glad you found the problem!
Try to play around with the joystick, move it all the ways and push it a little hard when you reach the edges.Maybe it will get fixed temporarly until you change it!

Hi! I have two suggestions to make.I'm not sure I will help you but you have nothing to lose! 1. If you use a pedal, unplug it and see what happens. 2. It might be a joystick problem.Try moving the joystick to all directions in case it has a problem, or go to sound mode->pitch and set the joystick ...

My problem was not the motherboard.It was the CPU Board.
These are two different boards.I hope I won't have problems again!

@paulmpianist: It costed 484 euros.I don't know if you can find the part alone but if it is not the same problem you will waste too much money!

@LESSISMORE: The guy who fixed it won't tell me the procedure.Sorry man..

Problem fixed with aftertouch calibration!

Hi again! The keyboard was fixed by replacing the cpu board. Today I got it back from service but now there is an aftertouch problem. The aftertouch gets activated the moment I press a key although it is supposed to be activated when I press the key all the way down. I have already done a format and ...

I talked to them on the phone and they have no idea of what it might be!
I hope it's something simple and inexpensive because my guarantee has expired!
I will keep you informed.

Thanks for the answer! I downloaded a fresh set of the OS and resources the first time that happened and I managed to install it after some tries because it froze during the installation. Now I downloaded those again but it always freezes! I think that the ssd is malfunctioning and needs change.Any ...

Here's my problem. A while ago I had a freezing problem with the keyboard and I thought I would format it and reinstall OS 2.01 and resources.When I tried to do that, I had to repeat the procedure many times because the keyboard froze during the update. Finally when I did it, sometimes when I turned ...

@X-Trade: I am not in front of the keyboards right now and I won't be until Wednesday but I believe the only options for assignable pedal in global setup are 'expression' and 'switch' but I am not completely sure. The other thing is that there is not an 'expression' option on the AMS list. I'm ...
