Hi. I was just letting you guys know that there seems to be a small bug in the XP-30's Arpeggiator. If you select certain combinations in both the Arpeggiator and keyboard, the XP-30 will freeze, then crash. Once you turn it off, then back on, it will display a massage saying "User Memory Damaged" and all of the user Patches and Performances will be erased, Replacing them with inaudible names like, "USER:001 _p_@__" I did a Factory Reset and everything went back to normal. (With the exception of all of my USER DATA being erased)

Here's what I did: (NOTE: If you try this yourself, MAKE SURE you have backed up ALL of your current USER DATA either by sysex, or Smart Media cards. Also, I only tried this with an XP-30 so I don't know if this happens with any other JV or XP synth/module)

First, I selected a patch.(Any patch should do) I then activated the ARPEGGIO mode. Then I went to the Arpeggio's parameters (SYSTEM/ARPEGGIO) and under Style I selected GLISSANDO. Under Octave Range,I selected -3. Then I pressed the -OCT button 3 times. (Making the keyboard 3 octaves lower.) then pressed and held the first key of the keyboard to listen.... That's were it froze, and then crashed.

Try it yourself. See if it does the same thing.I'm pretty sure it does this with all XP-30s.(At least I hope so...)

Damn, sure enough it did the same thing with mine too! I just got mine this week so I didn't mind loosing my user settings as they were still all the factory presets.

Does Roland have a firmwave upgrade system where they can fix this? I hope so.

Hi I tried out the test of the bug and it affects mine also. I have to say though that you no one would go 3 octaves below becasue you can't hear anything good! BTW you don't need to actually set the arppegiator to -3 octaves, all you do is set the Arppegio to Glissando, and press the -OCT button 3 times and press low C and it will crash. There simply is no point to having a firmwave upgrade system because most people have probaly never encountered it and of course its something most people would not do! Play an arrpegio in low low C. Playing at that is inaudiable!!! Enjoy the XP-30 for what it is, I have and its the most useful and best Synth I have used.
