1 – How do I use jBridgeM?
After the installation, run the jBridgerM tool, to prepare bridging files for your plugins, for a usage example, click here.
2 – What do the options do?
-Auto-close GUI: Closes the plugin’s window when you close the jBridgeM’s window
-Performance mode: Audio buffers will be processed asynchronously, can improve performance with some plugin/host combinations
-Run in existing auxhost: Disable this option for plugins that you want to run in their own auxhost ( by default, all the plugins run in the same auxhost, may be worth disabling this option for a 32bit plugin that uses a considerable amount of RAM ).
-Sluggish GUI hack: Enable this if your bridged plugin causes audio stutter when operating its GUI.
-Use thread safety measures in auxhost: Try enabling this option if you’re experiencing random crashes when running your bridged plugin.
-Bridged plugin’s GUI always on top: Creates the plugin’s window as always-on-top ( Will require that you close and re-open the plugin’s window for this change to take effect ).
-Dirty close: Bypasses some de-allocation routines, enable if you’re experiencing crashes when removing/unloading the plugin.
3 – How do I completely remove jBridgeM?
Open a terminal ( go to Spotlight, enter “Terminal” ) , then copy/paste and execute the following command:
sudo /Applications/jBridgeM/config uninstall
Reboot your machine in the end and it’s done. 🙂
4 – Is it possible to have the plugin’s window in the VST host’s window?
Please check here. This mode has some limitations, but should improve your workflow a bit. 🙂
5 – Why do I lose the keyboard shortcuts in my VST host?
– This is ( unfortunately ) a limitation of this implementation, your bridged plugin will be running in a different application,
which will get focus everytime you do any operation in the plugin’s interface.
6 – I don’t like the icon in the dock, can I run this without it?
– Some plugins will only accept mouse/keyboard input if they’re running in an application that has a dock icon, it seems. 
This is the best compromise possible currently, although I am still checking if it’s viable to make this optional or not.
7 – My plugin crashes when I unload it.
– Try enabling the “Dirty close” option, while in some cases it may not prevent the crash completely, it should not compromise any of your work, at least.
8 – I am experiencing abnormally high CPU usage.
– Try enabling the “performance mode” option.
9 – My plugin doesn’t work at all or crashes all the time when bridged.
Please make sure that you can run the plugin natively in your system ( without jBridgeM ), and that it runs without any problem that way. If yes, then it’s probably an issue with jBridgeM, please contact me with a detailed description of the problem ( please refer the plugin, the VST host you’re using, how does the crash happens, and your OS X version ).

10 – I am using OS X Mavericks ( 10.9 ) and I am having some poblems ( ie, my bridged plugins GUI is not being updated ).
Please check this section.
11 – The bridged plugin crashes when I try to load it inside Metaplugin or PatchWork:
Load the bridged plugin in a standalone VST host, and disable the “run in existing auxhost” option.
Alternatively, you can manually edit its bridging settings file in /Users/<your user>/Library/Application Support/jBridgeM/SettingsFiles and change the line
RUN_IN_EXISTING_AUXHOST 1
to
RUN_IN_EXISTING_AUXHOST 0
Also, make sure you’re using jBridgeM 0.93 or above.
12 – I cannot see the bridged plugin’s interface when running my DAW in fullscreen mode.
While this may not work in all macOS versions, try this:
– Enable the “Plugin editor in host’s window client area” or the “Bridged plugin’s GUI always on top” option in jBridgeM’s settings.
– In you mac OS “system Preferences”, go to “Mission Control”, and disable the “Displays have separate Spaces” option. Log out and log in again.
13 – My plugin’s GUI is shown very small.
– Go to /Applications/jBridgeM
Do this for both the auxhost and the auxhost64 app:
– Right click each and choose “Get Info” from the File menu.
– Place a checkmark next to “Open in Low Resolution” ( if this option is available ).
14 – jBridgerM’s icons are being added to the dock after I use the program.
– Go to System Preferences->Dock.
– Uncheck “Show recent applications in Dock”.
