Well, have you recorded the MIDI yet? Use the internal recorder to record the MIDI. Once the glitch occurs, just stop the recorder. Obviously, you should also record the audio at the same time, and give them BOTH recordings.

It doesn't matter if, when you play back the MIDI recording, the problem doesn't occur again. Just send them both files.

If you don't want the hassle of transferring the MIDI file to your computer, just buy a memory card and record it to that, and mail them the memory card. (heck, even if they never return it, given how long you've had this problem, it would still be worth the small expense, surely!!)

I would avoid using your computer to record the MIDI - use the piano itself.

Have a question, about the AP-620's built-in recorder:

Does it record indefinitely until you decide to stop it, or, is there a limit to recording time?

I would think it would record until the internal memory fills up. Then you would have to dump to an SD card to save what was recorded or just delete the file.

I AM ALSO EXPERIENCING THE CONTINUED SUSTAIN PROBLEM AT UNPREDICTABLE TIMES.....ALSO HAVE AN ISSUE WITH WOBBLY,CLACKING KEYS...THINK I WILL HAVE TO CONTACT CASIO!!!

Hi souwestriver,

I am glad to see that I am not the only one who has experienced the sustain pedal / resonance issue on the Casio AP-620. Take note that I have two Casio's that do this, the AP-620, and, the PX-130.

Do not exchange your current AP-620 for another one, as I have already done this. The new piano exhibited the same exact problem.

If you can record the resonance glitch to the AP-620's built-in recorder, save/transfer the recording to a 2 GB SD memory card.

Send the SD card to Casio so they can analyze the recording.

The issue has not been acknowledged, as of yet.

Have to ask as to why you are "SHOUTING" in all CAPS?

@pv88, should be no big deal if this doesn't happen all the time. PM should be just fine also regarding it's a valued new pianoworld member. I think we have more important things to discuss...

Ok - hold the phone.

I may have just experienced the problem that pv88 reported, on my PX-330. One note was still sounding after I had lifted off all keys and the sustain pedal. Instinctively, I pressed and released the sustain pedal again, and this terminated the offending note. I was using the rhythm accompaniment at the time. (I don't use it very often).

On the other hand, it could simply have been a mechanical problem with the sustain pedal. I'm using the basic footswitch pedal that came with the PX-330.

Greg.

This came up in another thread recently on a PX-130, and I mentioned that I encountered it once with my PX-330 also (using the fancy 3-pedal setup). Also, this is a pretty old thread, but still valid I guess. Not a problem with the foot pedal (mechanicals) for sure, imho.

Greg,

Can you capture this glitch on your piano, and, send it to Casio?

Probably not. It's only happened once, and I've had the PX-330 for quite a while now.

FWIW, I was playing a piece considerably slower than normal. (common time, tempo 91). The piece features a lot of triplet-trilling" in the left hand (so that would be a tempo of 3x91 = 273 bpm), and a lot of sustain pedal. I can't remember exactly where it failed. I lifted off at a point where I would not normally lift off - I was experimenting at the time.

Greg.

Greg,

That's okay, as it sounds like the issue you had may not be the same.

Extra note:

Deleted my PM since you have replied, here.

[Edited]

No problems - I was going to reply to your PM seperately though....

PV88,
Not taken seriously? I personally visited your home in order to witness the behavior which you were unable to duplicate. We picked up and replaced your AP-620. Yes you did send us an audio recording but it does not allow us to prove that anything is wrong. As for the SD Card, to whom did you send it? Why send a card when you could simply email the files from it?

Mike,

Thanks for the reply, however, please note that I never did manage to send a memory card (only the audio files) since I wasn't able to figure out how to actually transfer an internal recording to the card, and, didn't know how to format the cards, either.

Read the two posts by "Lelax" and "xorbe" as there may only be two other folks (at PW) that have experienced the issue, as it is "xorbe" that has put their finger on it, precisely:

And, I know that you do take everything I have said (or, shown you) seriously, so I apologize for that statement.

As I am no longer interested in pursuing the issue there will be no more posts from me on this subject.

Therefore, would like to lay this one to rest.

Best regards,

pv88
