v1.8.10

Beta build for Apple Silicon Macs (M1/M2/M3/M4), macOS 13+, Logic Pro.

A stability update to 1.8.9. Big pad presets such as Abyssal Orbit now use much less CPU, and MURMUR keeps playing instead of overloading when a patch asks for more than your Mac can render.

Install

Open Tidepool and sign in. It installs MURMUR and licenses it for you, so there is no key to paste.
Or download MURMUR-1.8.10-macOS-arm64.pkg from GitHub Releases and double-click it.
Quit Logic completely, reopen.
Settings → Plug-in Manager → Reset & Rescan Selection.
Software Instrument track → AU Instruments → Murmur → MURMUR.

What's new since 1.8.9

Lighter voices. Pads with lots of modulation, like the 24-voice Interstellar and Spatial presets, render about 1.6x faster. The sound is identical.
Overload guard. If your Mac can't keep up, MURMUR fades out the oldest release tails and lets new notes reuse voices instead of stuttering. Notes you're holding are never cut, and full polyphony comes back as soon as there's headroom. Bounces always render every voice.

Troubleshooting

Problem	Fix
Long pad tails end sooner than expected during heavy playing	That's the overload guard freeing CPU; raise Logic's I/O buffer size or freeze other tracks
The face is blurred and asks you to sign in	Open Tidepool and sign in; MURMUR clears the blur on its next check-in
Logic says "incompatible"	Delete old MURMUR.component, reinstall the 1.8.10 pkg, rescan
