Re: Trouble Updating VF-1 Firmware

The problem is a combination of computer speed and operating system. The best results are with a slow computer running dos. You can find dos programs that send midi files and sysex files.
Windows operating systems like xp and later are useless for this because of their multi tasking nature, the midi port data rate (not baud rate) will be erratic which over runs the vf1 buffer. Go back to good old DOS and your problem will be solved.
