### Enabling Realtime Scheduling

The TooB Convolution Reverb and TooB Cab IR effects require realtime scheduling to be enabled for the current user 
in order process convolution data on background threads while audio is running in realtime.

The procedure for enabling realtime scheduling varies between Linux distributions. 

Most modern distributions have the RTKIT DBus service, which allow programs to request realtime priority. But the restrictions imposed by the RTKIT 
DBus service may prevent the TooB plugins from starting. RTKIT does have configuration options, but the procedure for configuring RTKIT is unusually difficult. 
If TooB plugins exceed the limits imposed by RTKIT (or if the RTKIT service doesn't exist), the easiest solution is to grant realtime scheduling permissions to 
the current user.

The native Linux scheduler calls require the user to have appropriate permissions. To grant permissions for the TooB plugins, make the following
modifications to your system.

On many Linux distros, any user of the audio group is granted realtime scheduling permissions. Check for files in the `/etc/limits.d/` directory named nn-audio.conf.
If such a file exists, open it to see which group has been granted permissions. There should be a lime simular to the following:

```
   @audio    - rtprio   95
```

If the file exists, add your user-id to the audio group, and reboot to make the change take effect.

To grant realtime scheduling permissions to your user-id , add the following line to `/etc/security/limits.conf`:

```
    youruserid     -    rtprio   95
```
or add the following line to grant realtime scheduling permissions for all users:
```
    *              -    rtprio   95
```

Once you have made the change, reboot to make the change take effect.
