Okay. Now we have some info to work with. That Edirol UM-880 
is a USB MIDI Interface - which is most likely the cause of your 
AN1x specific issues.

I'm not surprised Local Off worked with the AN1x and could only 
guess that some previous error on the USB bus had resulted in 
a momentary glitch.

The AN1x reacts slowly to Program change commands. It's 
always best to leave a measure or so inbetween program 
change commands and the next MIDI Note On event. Again, a 
momentary glitch on the USB bus might have caused a buffer 
error on the AN1x - I expect you rebooted your AN1x at some 
point?

The fact your other Synths and sound modules behave as 
expected with Local Off and Programs Change on the UM-880 
eliminates the possibility of a configuration error in Cubase, i.e., 
that you have Program Change commands or SysEx filtered in 
Cubase.

I've not used USB on Win98SE but plenty of other list members 
have commented on it. Perhaps you should search the list 
archive. Have you doubled checked you're running the latest 
drivers for your UM-880?

I CAN tell you that AN1x SysEx dumps over USB can be a tricky 
thing - on either platform. AN1x SysEx packets are unusually 
large in size in comparison to other synthesizers. This presents 
difficulties over USB which has no provision for error correction - 
it's strictly a blind send and receive with no hand shaking. That 
said, it can be met with success. This has been discussed at 
length on this list over the past few years (see the list archives 
for more info.) When you performed your bulk dump did you send 
a '1 scene', '1 vce', '1-64 vce', etc. or 'all vce'? If you're not finding 
success with an 'all vce' dump try one of the other options and 
see if it works. Are you working ONLY with Cubase are have you 
tried the same with AN1xEdit? What were the results?
