# cpr2rpp: reconstructing the Cubase 12 project format

> cpr2rpp documents the empirically recovered Cubase 12 CPR project format and converts selected project data into REAPER RPP files. Its parser extracts audio-event timing and sources, mixer faders, pan, EQ bands, sends and pool clip metadata. Format notes describe the named-record grammar and compact arrangement-event encoding.
