I'm not sure about your particular editors with PC's or Mac's but I have a lot of issues with using todays faster PC's to send sysex to my older synths. The better USB midi interfaces are built for speed and can easily send too much data for the Matrix to handle. This alone will result in incomplete banks and corrupted patches. I use Midi-Ox in windows to send sysex banks. Slow down the transfer with delays and use smaller buffers by configuring the sysex option. Sometimes buffers as small as 32 or 64 bytes are needed with 100 milliseconds or more delay between buffers. Basically you don't care how long it takes to send a bank of patches as long as the M-1000 can write them to ram.

I can make an updated V1.11 eprom for your M-1000. There are also sellers listed on Ebay that offer this service if you have the bin file. Oberheim even though they may be defunct owns the copyright for this firmware so it's not a profit making venture. I only charge for the cost of the eprom and shipping. Usually $12.00 US total. Contact me offlist for the details.

> Basically you have two options : 1) As I think someone said, there's a Cubase editor out there - I run it on boot camp xp on a laptop and it's the only editor that won't crash the Matrix. Unfortunately it only has mod matrix presets so you can't edit everything but you can control the majority of the parameters. Sysex Librarian for Osx will load and save banks without crashing. That's about it, I tried them all nothing else worked :(
