Contour Max beta 1.2.2-maxbeta1

Superseded by Contour 1.3.0. Protocol Max support is now in the regular app, so you no longer need this beta. To keep a profile from it, send it to your Max from the beta, then save it in Contour with FROM DAC. After that you can uninstall the beta.

Contour Max beta is a test build with experimental support for the CrinEar Protocol Max. It installs next to stable Contour as a separate app with its own library, so your Contour library stays as it is.

New: experimental CrinEar Protocol Max support

• Strict USB match: 3302:43CC (taken from the devicePEQ capture, not yet seen on real hardware).
• Ten-band PEQ with native low and high shelves. Contour computes and writes the preamp itself.
• DAC import and device-aware profile matching.
• No EQ writes on connect; writes need an explicit tap.

Important limitations

This has NOT been tested on a physical Protocol Max. Protocol behaviour follows the devicePEQ reference. Start testing at a low listening volume.

• Contour refuses to talk to the device if its USB layout differs from what it expects. If the Max shows up but does not connect, please report exactly that - it is the most likely first problem.
• Without a Max plugged in, ten-band profiles show as invalid and clipboard import is cut to eight bands.
• A/B is unavailable on the Protocol Max.
• The Protocol Micro works exactly as in Contour 1.2.2.

If you have a Protocol Max, please try it and report what happens.

Verification

Core protocol tests: 17 passed, 3 skipped (they need a local EQ library). Both Max beta and stable variants compile. APK signed with the existing Chronosaur release key. Stable release v1.2.2 and main are unchanged.
