39. Using the Multihost plugin in Bitwig

Bitwig uses a sandbox process to host plugins. If you remove the last MP Multihost plugin and try to load another one, Bitwig will not be able to load it.

One option to address this problem is to always keep one Multihost plugin loaded.

 The other option is, if you have removed the last one Multihost plugin, just double click on the MPHCSM.exe (Windows in the ~/MP/Host folder) or MPH Cache.app (Mac in Applications) to clear the cache and load the Multihost plugin.

Important: In Bitwig setting > plugins > Plugin hosting mode
set it to: Bitwig or Together or Vendor
