Also why do some plugins make loads of different versions? – Cube for example has a Cube 1. Cube 2 – a dozen variants. It’s making the whole plugin menu look rather messy.
If those mappings are inside a subfolder, then the plugin is imported as a global plugin, meaning there are separate mappings for accessing the multiple input/output and MIDI channels for a single plugin instance. If you only intend to use the plugin with a single MIDI channel and single input/output it will be easier to use the plugin with an insert mapping. Use the “new insert mapping” command when right-clicking one of the plugin mappings in the start page device list.
