Using _ audio command midi vst plug and a number for a buffer container (there are only four midi channels for a VST: 1, 2, 3, and 4), allows you to choose an VST instrument from your machine. After which, writing the Orca characters _ v 0 2, (notice channel number is 0) opens your instruments GUI (in this case the VST instrument in channel 2).
