Roland Answered Questions & Fixed Issues

If it is a drum machine, why have you posted this query under Cameras ? You may get more help posting it under musical (and I use the term loosely) instruments.

hi there. see if this link helps you out. Roland xp 50 main board sound problem Google Search

Well it could be a sereis of things. First of all, check compatibility with your opperating system, if that is ok go back to the Korg website and re-download again.

Go to "YouTube" and type in "Roland FP8 piano repair"

If the PSU is a switch mode type it is clearly faulty but if it is a transformer type checking it open circuit or off-load will usually result in a significantly higher voltage than specified. In order to check the latter type it is necessary to first apply a load approximately equivalent to the device it would be powering if the device was working normally. Sorry I can't answer the rest of your question...

I have the Boss ME 50. Here's things to try. Use wall outlet to power the 25 instead of batteries. Have volume on amp up, volume on pedal all the way up, volume pedal all the way up(depressed), no gain on amp(use clean channel or clean setting if only 1 channel)effects on amp off(reverb, chorus, delay, boost, etc.) mid range knob below 5. only 1 pickup on, guitar tone knob all the way towards treble. If this puts you in the ballpark you can then make slight tweaks to any of these settings. What we're trying to do is not run a dirty sound from the pedal board into an amp with dirty settings. That double dirt often causes a muddy sound. Aside from that you can back off on various effects in the patches. My 50 has a list of the patches and factory settings, so if the drive, for example is set on 8, I might back it off to 4, or the compressor, or the delay, etc. If you like the sound save it. If not continue on. Start with the amp 1st. Higher output tubes(such as JJ's produce a cleaner sound. Also the demo you heard was not coming from your guitar speaker which may not be on the clean side.

Did you check the solder connection on the jack where it connects to the motherboard? That's a high stress point and could simply be a broken contact that needs to be resoldered. Should be 3 or 4 pins likely.

Get the manual from web site and it will tell you how to replace the battery.

I would suspect a setup problem. Your best bet would be to contact Rolan Customer Service. /here's their link- Roland Support

You have a ground problem. I suspect your cord. Replace it, being sure you use an instrument cable, and see it that doesn't help.

Mine did that. Found out it was the input jacks

Open up the Roland E-80 and check if all connectors and flatcables are well seated.
