Re: [analogue-sequencer] CHK FAIL = 2681

2011-01-31 by Tom Adam

Yes, this seems to have done the trick. It's been happily running for a 
couple of hours.
What could have caused this flash rom corruption?

(is there a .mid for v4.5 somewhere? Or what tool is there for linux to 
send a sysex file? I've used kmidimon to upload the 4.0 mid version.)

Cheers,
Tom
