## What is Mooring for FM?

Mooring installs firmware on the M-VAVE FM-1, the pocket FM synthesizer, from your iPhone or iPad over a USB-C cable. It is an independent app. Mooring is not affiliated with or endorsed by M-VAVE or Cuvave.

PRACTICE FIRST
Mooring opens in Practice every time. A simulated FM-1 replays a recorded update, so you can go through every step, including the review and the hold-to-flash key, without a synthesizer and without sending anything to a device.

KNOWN FILES ONLY
Every file is read, hashed and checked before anything is written. A file on Mooring's pinned list, or on a newer list signed by the developer and checked by the app, is marked Verified. A file that looks like an FM-1 package but is not on the list may be a rogue or untested build, and needs an extra acknowledgement. Anything Mooring cannot read as an FM-1 package is refused.

A PINNED CATALOG
The Firmware screen opens with three Staff picks, then stock V15, then dozens of community projects. Download stock V15 from M-VAVE's own server, or community firmware from each project's GitHub releases or, when an author publishes no release, the Firmware Hub's hash-checked copy. Every entry is pinned to an exact SHA-256 and size, and every download is checked again when you load it. Each time the screen opens, Mooring fetches a firmware list signed by the developer and checks the signature on your device, so new firmware can arrive between app releases. A list that fails any check is ignored, and the list cannot change the app's rules. Mooring hosts no firmware. Files go into Mooring's folder, which the Files app shows too.

REAL FM-1 ACCESS IS YOUR CHOICE
Writing to a real FM-1 stays off until you turn on Real FM-1 access in Settings and confirm. You can turn it off at any time, and Mooring still starts in Practice.

KNOW THE RISK
A failed or interrupted update can leave the FM-1 unable to start, and recovery needs a computer and extra hardware. Custom firmware expects stock V15 to be installed first. Mooring shows the recovery resources before you flash, and nothing is written until you hold the key. With Real FM-1 access on, Mooring checks at launch for an FM-1 left waiting in update mode and lets you finish the update it started, with the same file.

SEE AND HEAR THE UPDATE
The review shows what will change and the checks to tick before the key arms. While it writes, an LED counts the blocks and a six-operator chart lights each step. Audible flash turns the firmware into quiet generative tones as it is sent; you can switch it off in Settings.

USB ONLY
Mooring talks to the FM-1 over a direct USB-C data cable, one FM-1 at a time. It never uses Bluetooth.

NO DATA COLLECTED
No account, no analytics, no tracking. The signed list is fetched from GitHub and carries nothing about you. Downloads go straight from GitHub, the Firmware Hub or M-VAVE's server to your device.

FM-1 is a trademark of its owner.
