Fission Splits, Say Hello to Physion

Visit the Physion Product Page

Physion plug-in UI screen shotShortly after we launched Fission in 2017 we were notified that another software product had been named Fission and, in response to a formal request, we decided the best thing to do would be to change the name of our product. So, from now on Fission will be known as Physion.

We apologize for any inconvenience or confusion this change might cause, but we chose to spend our time, money and energy on product development rather than in legal wrangling over a name. After all, a rose by any other name…

If you have any questions, please read through the FAQs below as they may contain the answer you need. If not, or if you run into a problem, please contact our support team.


When is the Fission/Physion name change effective?

The change is effective immediately.

Is Physion a different plug-in from Fission?

They are the same plug-in. The name change is simply that and only that. Physion IS Fission!

How do I update to Physion?

Simply download and run the Physion installer for your OS. You may also want to update the license name in iLok License Manager. For instructions on how to do that, click here

If I already own Fission, do I have to update to Physion?

There is no requirement to update, though we strongly recommend you do so, if only for consistency with online documentation, support, etc. Plus, by updating to Physion you will benefit from ongoing bug fixes and optimizations.

If I already own Fission and update to Physion, will my existing Fission license still work?

Yes, the license is the exact same. In iLok License Manager, you may notice that the name of the license is still "Fission." You can update it by following these instructions.

Whether you update the name in the iLok License Manager or install the updated plug-in, your license will still work. If it does not, please contact support.

Will I lose my settings or presets if I update to Physion from Fission?

There is 100% session compatibility between Physion and Fission so you will not lose any settings or presets.

I updated to Physion, why does my DAW still show the plug-in name as ‘Fission’ in effect inserts and/or the available plug-ins menu?

Some DAWs cache the names of plug-ins in their general settings, or in session settings (e.g. for insert names). Resetting the DAW’s cache files and rescanning your plug-ins should fix this issue.

In particular, if you are using Logic Pro or GarageBand, you can reset the cache with the following steps:

  1. Close the DAW
  2. Delete the following files from your User Library, if they are present:
  3. Reopen the DAW

If you are using REAPER, the plug-in name will update in the Add FX menu, but not in the insert field of sessions previously created using Fission. This is because REAPER stores the insert name locally when you first add the plug-in as an insert. You can right-click the plug-in insert, and select "Rename FX Instance", to update the name.

While these are currently the only known DAWs with this issue, it is possible that other DAWs might have the same issue. Clearing the plug-in cache will likely solve the problem. And, even if your DAW still displays the old name, as long as the actual plug-in UI says "Physion," you have updated correctly.

How do I see the new Physion name in iLok License Manager?

In order for you to see the name change, do the following:

  1. Ensure your computer has Internet access
  2. Launch iLok License Manager
  3. Go to Preferences > Licenses and select Remove Account Data Saved On Computer
  4. Relaunch iLok License Manager and sign in
