|Note: old OS versions will no longer be available from my page. They could be causing problems that unfortunately nobody has the time to remedy...
Please send all questions you might have about OS versions to the mailinglist (for infos on how to get on the list follow the link to the mailinglist page.
The README (enclosed in the archives) contains important information about upgrading. To make sure you don't accidentally erase your sounds, be sure to read it!
The file format is .zip, a standard format for most computer platforms. I used .hqx (a Macintosh format) and .mid (MIDI-File) before but those were causing me too many questions and too much trouble. There are free utilities around the net that can easily unpack the .zip format.
The Format of the MIDI file itself has now been changed to format 0, enabling the QY700 to directly play back the OS to the Virus.
Version 2.52 for VIRUS a is a "user-update", it contains many features that were requested on my wishlist and the Access-list (the Virus user mailing list). New features include: simplified update procedure, new LED modes, new Control Smoothing modes, the Virus now reads Expression control, audition feature, Arpeggiator quantise and more.
Please refer to the Readme (anclosed in the archive) for details.
