Can't Delete Imported Midi Drum Tracks

I was playing around with the idea of importing MIDI drum tracks. My first attempt did not work - so I decided to delete the imported MIDI track - however, I can’t. When I right click on the imported track there’s no option to delete the track. I want to delete the track that says “VST Instruments” and everything underneath it. (see attached) What now?

Hi,

This is not the MIDI track. This is the Audio Return of the VSTi. Open VST Instruments (F11 or Racks), click to the HALion Sonic SE and select No VST Instrument.

Thanks, that worked!
