Loading VST and MIDI instruments manually
Dorico automatically loads enough VST slots for all the samples required for your project. However, you can also load VST and MIDI instruments manually, either into new slots or into existing slots to replace existing VST and MIDI instruments.
Prerequisite
You have any VST instruments you want to use saved on your computer.
In order for MIDI instruments to be available to load, you must plug them into your computer before starting Dorico. If you plug them in after starting Dorico, you must restart the program.
