Great news Jake. I got that 1.12 OS from a Roland Tech who knew about the dud 1.13 OS on the Roland Japan website, and has notified them about it, to no avail. He had this good OS on his service computer for whenever people bricked their MS1s with the dud one. Apparently they never brought out a goo...

I dont have any pics, but open the battery hatch and remove the battery holder, just solder a socket to the connectors and then find a convenient place to drill a hole in the hatch that allows the socket to fit

It sounds like your plug is a slightly small diameter which doesnt fit in tightly. You could try a different power pack. In any case, if you are intending to play live with this thing, a power supply is a disaster in waiting. I use rechargeable NI-MH Eneloop batteries in mine. One charge lasts for w...

Ebay is your best bet. Heres the RAM card here: https://www.ebay.com/itm/324802716620 Also straight google seach brings up some. Also the Hohner HS2 RAM card fits it. Also the ES100 RAM card: https://www.casio880.com/en/product/module-es-100-ram-card-64kb-compatible-with-vz-ra-500-521/ The RC100 ROM...

Boosting the level with a pedal will work but wont get the balance between the guitar and synth level right, out of the mix output, where you need it most. My mod makes a significant difference. Otherwise I wouldn't have done it. I gig all the time with it. Here's my band: https://www.facebook.com/a...

Sure. Although the mod is so incredibly simple, you just stick a resistor on top of another resistor. You could even just use the resistor I mentioned and 2 alligator clips to test it out, would take about 2 minutes to try. You just unscrew the output jack plate from the guitar, leave all cables con...

You can adjust the synth pickup sensitivity volume in the user manual, it shows you how. Under one of the rubber plugs on the back is 6 Phillips head adjuster screws for the sensitivity of each string. You can get it louder there. Have the caps been changed on your boards? This is a comon problem wi...

There used to be a Yahoo group but sadly that died with all the yahoo groups. My band page hosts a lot of the info of those sites, eg service manuals, schematics, , tracking malfunction repairs, mods etc. As all the PG guitars 300, 310 and 380 have the same synth boards and electronics, the 380 sche...

Make sure your UM-1 is in Advanced mode. There is a little switch on the side of it. If it isn't in Advanced mode, it won't pass sysex information, only note info. Try putting the switch in the other position, then send it again

OK tell us more!!

Hah thats great news! Good tip for anyone sweating over this wonderful machine. Don't ever give up on it. I see these machines selling on ebay bricked going for a song because people didn't know what we do...

OK everyone, I've just uploaded the MS-1 BIOS v1.12 to my server. Here is the link: http://www.warningwillrobinson.com.au/index_files/InstrumentManuals.htm Look for it under the Roland heading. It is a bundled zip file that has the whole kit of all things MS-1, including the v1.12 good BIOS to fix y...

Send me a PM with your email address, I'll send you the file

You don't need a flash card to update the bios, just a computer and a MIDI port or USB/MIDI adapter

Cheers, Graham

Sent you the file. Good luck!

Actually double shame on them - they provided 2 corrupt files - the 1.13 version AND the 1.12 version (on their support website)

I think there is confusion between Roland US techs and Roland Japan Techs communication. Must be the google translator they use!

If you got the v1.12 OS off the Roland website, it's corrupt. I've used it. I got the good v1.12 after emailing Roland support, and they sent me it, which is the one I will give you
