If you have an XP, you could easily load in the SVQ file and then re-save it as an .MID file.
If you have a JV and a computer, there is a nice third party program available somewhere on the net (look on the JV/XP ring) called SYSX2MID. This program will convert andy Sys-Ex program to MIDI. You could ask a recent audio/MIDI program for a SYSEX request, play the MIDI file from the computer and set it in a loop so the computer will recieve the MIDI info as Sysex data. You then use the SYSX2MID program to convert the old SVQ file (Which would now be a syx file) to .MID!
I hope this helps!
