Ableton (added 15th Oct)
Ableton has released this information on their support pages....
Is Live 9 compatible with macOS Sierra? - We are not aware of any issues affecting the latest version of Live 9 (currently 9.7) under macOS Sierra. However, older versions of Live 9 cannot be expected to function flawlessly, nor is Live supported on the beta version of macOS Sierra. The latest Live version is available for download in your account, and we recommend making sure that your Live version is fully updated.
Is Live 8 compatible with macOS Sierra? - Live 8.4.2 is not compatible with macOS Sierra. The latest operating system to support Live 8.4.2 is Mac OS X 10.9 "Mavericks".
Is Max for Live Compatible with OS X 10.9? - As of version 7.2.4, Max for Live will work in macOS Sierra. However, for users that upgrade the OS (as opposed to reinstalling it), it is necessary to perform a Java 6 SE installation a new time.
Other information - As always, be sure to make backups of any important data before upgrading your operating system! If you plan to upgrade to macOS Sierra, please be aware that there's always a risk that a new operating system introduces unforeseen problems or incompatibilities with your existing software. This does not only apply to Ableton Live, but also to third party plug-ins, hardware drivers and whatever other software tools you are using. We strongly recommend checking with each manufacturer that your software and drivers will work with the new operating system. If you are working on any time-critical projects, we'd recommend staying with your current operating system for the time being. If you upgrade and experience any problems, please contact Ableton support.

BaseHead 4.x is compatible with macOS 10.12 minus the ability to show a 'Group' in the Results List by left mouse clicking on it if using 4.x Standard or 4.x Ultra. This function can still be done if the user right clicks and chooses it from the contextual menu though. The next update should solve this one broken issue that 10.12 caused.

- Reaper VST2 32-bit: there is a crash when opening our GUIs
- Cubase VST2 32-bit: our GUIs appear empty (black window)
- Gobbler application (specific to Slate Digital subscribers): logo and buttons are missing
They are busy currently working on these issues.
Michael Carnes has announced on a thread on the DUC that all his plugins are good. he says...
All Exponential Audio plugins are fine on Sierra. And graphic performance is much snappier there for every DAW I've tested (compared to El Cap). I've been testing on a 2012 Mac Mini and it's zippier than my trashcan. Purely by coincidence (I wanted to have this sooner, but NIMBUS has kept me busy) there will be new betas of all my other plugs later today. A number of small issues have been addressed and graphic performance might be a teensy bit better.
Of course there are other reasons you may have to wait to upgrade (I'm still waiting on UAD drivers), but Sierra appears to be a much better performer than El Capitan.
Eventide (Added Sept 24th)
Eventide have announced that while there are no issues with Eventide plug-ins on macOS Sierra, there may be incompatibilities with your DAW and other 3rd-party plug-ins.

Metric Halo (Added 24 Sept)
BJ Buchalter, VP Research & Development, sent this message to MIO Users on September 19, 2016
As you may know, Apple is due to release macOS 10.12 (Sierra) tomorrow. We have just posted an update to the MIO software on the website that is required to provide compatibility with macOS Sierra. This version is also compatible with macOS back to 10.6.8.
As is the case with every major Mac system software update, you may want to hold off updating until you are sure that ALL the software and hardware that you depend on for your day to day work is fully compatible with 10.12. There have been some changes to the OS that may cause problems for some audio software or hardware, so you should make sure that everything you depend on is compatible.
That being said, all Metric Halo software and hardware (MIO, SpectraFoo, and the Production Bundle plugins) is compatible with macOS 10.12 - as it has been for all the OS launches since 10.4, so MH won’t hold you up from upgrading.
In addition to providing driver compatibility for 10.12, the 5.6.08 update for MIO adds a number of fixes and features.
BJ recommends that this update is for all Metric Halo users because if you plan on updating your OS to Sierra, you will need to update your MIO software in order to continue using the driver.
MOTU (Added 28th Sept)

Current versions of all MOTU software products and most hardware drivers available at motu.com/download The latest versions appear to be compatible with Sierra, although final compatibility testing is still on-going.

Don't Do It - It's Too Early
Even though there are a growing number of announcements so far on mac OS Sierra compatibility and there are a number of positive reports of people having success with Sierra, our advice is not to go there until Avid have approved it, all the plugin brands that you use, have approved it AND you have some downtime to do the update and deal with any issues.
We will update this article as more information comes in and do share any news and experiences you have had in the comments below.
