What it is
A browser-first workspace for vintage CZ patch management.
CZ Explorer is for musicians who want to keep hardware patch libraries organized without adding another desktop utility. It focuses on the real workflow: finding sounds, grouping sounds, and moving SysEx data where it needs to go.
SysEx import and export
Move classic patch dumps in and out of the app so old libraries stay usable.
WebMIDI transfer
Connect supported browsers directly to hardware and send patches without a native install.
Always free
CZ Explorer is a free utility for musicians keeping vintage CZ workflows alive.
No checkout required
Open it and start organizing patches.
CZ Explorer stays free. The support checkout is separate and optional, for people who want to help fund the surrounding Purr Audio work.
