USE

How

First, copy patched carla application to Windows from dist directory in carla-sandboxie-patchset, and launch Carla.exe same as non-patched Carla.

Second, setup some configuration to Sandboxie-Plus, patched Carla and Environemnt variables, and information about this configuration is on the next Restrictions section.

Last, add full path about scan plugin directory inside sandbox container to Carla's configuration, and rescan plugin by Carla like as non-patched.

Finally, you're suceed all steps, you're enable to load VST pluguins from Sandboxie-Plus's sandbox container.

Restrictions

this patchset features has some restrictions, see below:

CARLA_SANDBOXIE_PREFIX and CARLA_SANDBOXIE_START must sets

CARLA_SANDBOXIE_PREFIX is root directory about Sandboxie-plus sandboxes, and CARLA_SANDBOXIE_START is path to Start.exe via Sandboxie-plus.

For example, your sandboxes root directory is C:\Sandboxie, CARLA_SANDBOXIE_PREFIX is C:\Sandboxie.

And if your installed directory of Sandboxie-Plus is C:\Sandboxie-Plus, CARLA_SANDBOXIE_START is C:\Sandboxie-Plus\Start.exe.

You must add some configuration to Sandboxie-Plus's Sandboxie.ini

In sandbox container, you must set this configuration to Sandboxie.ini for getting works fine about load VST plugin from sandbox container:

OpenPipePath=%temp%\*
OpenIpcPath=\Sessions\*\BaseNamedObjects\carla-bridge_sem_*

Always use plugin bridge on Carla

Last, patched carla requires to always use carla's plugin bridge feature, And you're enable to this feature by these steps:

1. Launch carla application, and click Configure Carla button.
2. In Main, checked Enable experimental features in Experimantal section
3. In Experimental, checked both Enable plugin bridges and Run plugins in bridge mode when possible

Sandboxie-Plus deletes sandbox container after the some days by default

You should block this feature by Sandboxie-Plus, and you're enable to block this behavior by adds this configuration to Sandboxie.ini:

NeverDelete=y
AutoDelete=n

KNOWN PROBLREMS

_carla-discoery-win{32,64}.exe sometime reports crashed

This problems maybe trigger by carla default behavior, but I'm not understood why triggered this behavior.

This problem has spamming SBIE2224 error to notification, but workaround is disable SBIE2224 error notification on Sandboxie-Plus notification panel.

Carla.vst cannot load as synth on FL Studio

This is a upstream bug of Carla, See Carla's issue report #1054.
