ZPX Sample Player (Beta)

ZPX is a sample player plug-in with auto-mapping and zip file loading capabilities. It can load and auto-map samples contained in a .zip or .zpk file, and will automatically parse embedded .sfz or .zpm mapping files if present. In-built save-as functions let you export the mapping code and package everything as a single-file ZPK instrument.

The auto-mapping feature relies on a very simple file-naming convention: note_vel.wav. For round-robin, you can use note_vel_x.wav, where x could be any letter or number. Both MIDI note names and numbers are recognized (e.g. C1_80.wav or 36_M.wav). For velocity, L | M | H (low, medium, high) are also accepted (note: this auto-mapping system is for version 1.01. A more advanced system will be implemented in version 1.02).

This plug-in is in Beta, and is still unstable in some hosts/systems. Thanks to Dan C. and others who have purchased licenses early, I have found major bugs that didn't turn up under my setup. I've temporarily disabled the 'buy now' button for the license. I'm currently re-working some GUI-related code to fix the problem. Feel free to download and test.
