Patches and discussion for Ensoniq VFX family

I've encountered the VFXlib problem even in pre XP times and the same can
happen with Soundlib when sending patches.
As far as I remember it's a timing problem, i.e. if your PC is sending too
fast the VFY can't keep up and produces this error message.
Both VFXlib and Soundlib have been developed at times with much slower
processing capabilities. 
With the modern fast processors you've got to throttle the output sent to
the VFX.
Other than midi sequences sysex files are sent a buffer full at a time. If
the receiving device can't process and empty the receive buffer
before the next bulk of data is sent there will be a problem...  
 
There's a workaround worth trying:
Get MIDI-OX and the MIDI Yoke driver to loop your MIDI signal through. In
MIDI-OX you can configure buffer sizes which might already help.
To try out settings use the Sysex window to send a patch file to your SD.
There you can even adjust a wait time between sending buffers.
 
Maybe you've to play around a bit but you'll at least be able to download
patches to your VFX or SD.
 
The other Soundlib problem with the access violation could be caused by an
installation gone bad. Reinstall soundlib and make sure not to
choose an installation path with names Soundlib can't easily cope with. Make
a directory C:\Soundlib and install Soundlib there. This worked for me.

I tried VFXlib but didn't have any luck getting the VFX SD1 to work at 
all with it. I then tried Soundlib and was able to pull the sounds off 
the VFX but can't export any of the patch to the VDXSD1 
I Get ....
midi sys-ex recieve error on the VFX 

and

Soundlib caused an access violation in winmm.dll at ox76b51571 on the 
computer. 

I did download the patches into soundlib...so I know the Midi 
connection is working ok
Anyone have any suggestions??

Thanks
