I found some nice VST things I would like to add to the library, specifically MT Powerdrums. I follow the instructions, and although the VST manager sees the file, and it is in the Media tab, it is not accessible. So, does LE 10 support 3rd party VSTs? If so, what is the proper VST folder that I should put the .dll and .pdk files into?
Yes, Cubase supports 3rd party VST. By aware this is an Instrument. Add an Instrument track, you should see the MT Powerdrums here in the list.
