Patches and discussion for Ensoniq VFX family

I just purchased a USB MIDI interface (Yamaha UX16) for my Windows 
98 laptop.  The driver is able to communicate with my VFX.  I 
downloaded and installed Soundlib, but in the configuration menus 
there are no drivers listed in the drop-down boxes for "MIDI In" 
and "MIDI Out."  Actually, there are no devices at all listed in the 
drop-down boxes.  I downloaded a sequencer, Jazz, which recognized 
the Yamaha UX16 driver without any problem.  The driver is also 
listed in the "Control Panel > Multimedia Devices" MIDI list.

Anyone know what might be the problem?

Thanks,

Will
