Stable release of the latest SFZ patches as of 1.2.2. Download this if you want to use the SFZ files from VCSL!
If you wish to automatically update VCSL in the future, consider using Github Desktop. The easiest way to keep up to date is to set up a local copy of the repository with Github Desktop, then just 'Fetch origin' whenever something new comes out. Install Github Desktop, then back on the VCSL main branch page click 'Clone or Download' then 'Open in Desktop'.
If the download fails to work, despite trying with multiple browsers and networks (if available), then use this mirrored version. Please be sparing, though, so others may enjoy this library too:
