I am seeking closure on this, it's very strange. I have a Kurzweil SP2X that just freezes after some period of play. This is aggravated especially when I turn on many features, such as layering, split and all that. I've taken it to a couple of local keyboard repair guys but weirdly, the freezing doesn't happen at the store, so they can't find anything wrong with it. Anyone experienced this or heard of it from someone?

A couple of thoughts on this.

1) It could be thermal. Is it more likely to happen on a hot day without air conditioning?

One way to test this would be to warm it up with a hair dryer while playing to see if it pops up.

Maybe open up an access hatch in the bottom if one exists and fire the heat directly inside the chassis.

2) it could be corrupt firmware. Have you tried reloading the firmware and seen if it makes a difference?

3) It could be power utility related. Do you live in a rural area or in a country with noisy, crappy mains power? Best way to check this out is with an oscilloscope to see if the waveform spikes or glitches at all.

Those would be the three things I'd check. The firmware is the easiest to check. The thermal is something any decent technician should have checked but nowadays anyone can pass themselves off as a tech without any credentials so it might be worthwhile to try the heat test yourself.
