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.
