Plenty of others are having the same problem, including PC users
too. The deal is that when you send a single patch that you have
downloaded from here it works because it is a tiny lump of sysex
being sent out the MIDI port to your MS2K. Its only about 300 bytes.
However when you send a full dump of 128 patches the MIDI interface
is getting overwhelmed by the speed at which you're asking it to
send this 30,000 byte monster sysex message. You get zero feedback
from the MIDI drivers but what has happenned is that the MIDI
interface has just thrown away a bit of it rather than sending it,
and the MS2000 just sits there wondering what hell is going on ;-)
So the solution most software takes is to send the data in small
chunks with a nice big pause between each chunk to slow things down
to a speed your MIDI interface can cope with. Look at the
preferences dialog for SysEx, Steve Grace has provided some
excellent options for slowing down how quickly sysex data is sent,
and for setting pauses between messages etc. Experiment with
different settings, and please tell us what worked for you; I'd be
interested to know.
