Prophet VS

Greetings Prophet VS users.

 Thanks for setting up this user group & thanks to those that have posted files info etc.

 I just got my Prophet VS back fully repaired ( including the joystick) after it being completely out of action for 11 years, so Im naturally delighted to be playing & programming my favorite synth again.

 I lost all my sounds though ( years of programming) which I expected.
 I have an original sound (ROM) cartrige that came with the VS when I bought it 2nd hand in the 1990s, but it never worked unfortunately.
 Anyone know if the cartrige needs backup batteries?

 As per thread title, I want to backup my sounds now that Ive been programming again & have run out of space, but Im nervous of doing this via SYSEX , because I have not managed to get Vector Surgeon running on my Mac & naturally dont want to lose my sounds.

 Can I just use 'SysEx Librarian' to backup & load Prophet VS patches?
 I have used it for backing up & loading Korg Wavestation / Z1 & Roland JD800 files without any problems.

  Does anyone have 'Wave Wrangler' or happen to know where it can be obtained from?

  Peace & Light                     Paul
