This is a patch converter utility, to make the patches saved with previous versions (480beta and before) compatible with the new amplitude envelopes.

Dependencies:
 - gzip.exe - from http://www.gzip.org/gzip124xN.zip; used for file compression / decompression
 - scrrun.dll - Microsoft Script Runtime (used for file access, browsing, dir tree extraction)

The instruments included in this package have already been updated for envelopes with 100dB max. attenuation.

Use this if you like to update your own older .xiz patches.
It is not guaranteed that after the update the instruments will sound exactly as in the previous versions, but the ADSR parameters will be updated to get the best match possible.
