Does any body have this problem?

Yo 2 all,

hear this...
Sometimes when I turn on my keyboard and press the keys the sound detunes on its own. I don't have anything (midi or otherwise plugged up to it) Also, when playing along with normal CDs, it's not in tune, so what I do is set the Master Tune to -50 cents (427.47 Hz)

Anybody else had this problem? could it be rectified or do I save that global setting for life?

thanx

It could be one of two things.

1: The joystick is not returning to it's correct position correctly or it is somewhat faulty.

2: Personally though I'd be more likely to point my finger at the Power Supply your feeding the keyboard. It's come up many times before, tuning issues due to poor quality power supply. If you feel the power in your area is not of good quality and you feel this could be a problem. Then buy a UPS.

You can pick one up at any computer store.
Something like this is what your looking for

Yes! I have this problem...

***Reading Sharp's answer now I know why that is.

I have this problem all the time. Once I tune with the rest of my band it sounds okay. Until I change sounds then i am out of tune again. but after tuning I will play some and then it will slide back out of tune. Are you saying that just getting this UPS will do the trick?

I found a strange tuning problem that is very apparent with mono patches. It may or may not be the same problem that others are experiencing.

I haven't messed with this in awhile, but I think this is how you can hear it:

Select a mono patch
Hit a low note and hold the key down
While it's still down, press a high note really fast (to trigger a high velocity)

I'm relatively certain that's the scenario that shows the tuning issue.

That's weird - I just tried it and can't seem to duplicate it. I know there was a way before that I could always get it to detune intentionally. And it wasn't a good detune...

well this low note to high note thing might actually be different thing altogether... it is called aliasing. If you have a mono patch which is legato and you hold a low note and then play high note the sample of the low note stretches to the frequency or pitch of the high note. This causes a lot of weird ringing sounds and other noise in the sound because the sample stretches too much and starts to sound bad.

Hmm... I just tried it again, and was able to reproduce it using some synth sounds that I sampled and then programmed into the E bank. I wonder if my issue is only reproduce-able using the sample RAM? I wasn't able to reproduce it using the factory sounds. It just might be aliasing. It sounds like a weird detuning - not quite like a typical aliasing sound.
