Annoying buzz produced from all monitor/line-out jacks
I bought a used (though claimed to be untouched) 2488 about a month ago, and me and my guitarist have been trying to figure out how to eliminate a buzz that comes out of our monitor source no matter which output we use. We've tried a couple power amps (an older Sony and a newer Pioneer) and both of them buzz. I don't believe it comes from within the machine because headphones are completely silent. Anyone know how to get rid of this or where I should send the machine to fix it, or is this beyond repair?!

A 1/4 inch short instrument (mono) cable between the AUX unbalanced 2488 and the 1/4 inch of the Voiceworks should work. Operate ALL the equipment from the same power source to avoid ground loops.
You will lose 3 Db since you will only be driving one side of the balanced VW input, but there is plenty of gain. The sleeve of the mono into the VW will ground the - balanced input of the VW. The connection is absolutely safe. Should you encounter noise on the connection, use an isolation device like a DI and use ground lift with the 2488 into the mono jack of the DI and XLR out of DI into the VW. I think you will find this unecessary though in your use.
If you're using the Play n Charge kit, then you might be hearing some buzz/whine through the USB power. Use the X1 without the Play n Charge. Does that help?
If you unplug the chat-controller cable from the X1 volume control box, can you now hear shots and explosions without the annoying beeping/buzzing noise? If so, then you may have a bad chat-controller cable, and you should have it replaced.
MIDI only carries digital information, not audio. Midi is used to communicate patch settings and note value information. If you want the recording to know the note value, then you should use midi. This is useful if you want to do things like adding rythm tracks, etc.
If your keyboard has audio/line out (as opposed to headphone out), use that, as it is matched much better in impedance. If it doesn't have audio/line out, then you can use the headphone jack, but you will have to turn the attenuation way down because the headphone jack impedance is much higher. This will tend to distort on the recording if you are not careful.
The first thing to know about digital recording is that distortion is much more of a problem. I won't get into the theory of this, just know that impedance mismatching is more of a problem with digital.
Repartition and format the hard drive. There are specific instructions elsewhere on the Internet. I did this about six months ago. I believe my problem came about after I stored my 2488 on top of my monitors - I believe the exposure to the magnetic fields corrupted the boot partition on the drive.
To reset the 2488 to factory defaults: Simultaneously press quick routing/shift/send/shutdown & turn on the unit.
The 'stop' button problem may require a look under the cover to see if the button is dirty or damaged under there. A good cleaning might do it. As for the 'no guitar out the monitors' issue, this sounds like it might have something to do with the setting of the monitor selector. Make sure it's set to 'stereo' and not effect loop or effect send or even muted. You might want to also make sure your monitor level pot is working properly.
the 12V is for speakers.. the 245bw takes regular 120V AC (same cord as your computer)
the buzzing is annoying, though. i don't know if it's a "feature" or just a side effect.. ie, if i could take the case off and poke around, i would. 4 times out of 5 it's some dumb piece of tin reverberating from a transformer or something..
