WOK has released Ghost, a freeware drone synthesizer instrument for Windows.
What is it? Something that makes a sound.
How to use? Adjust Attack/Release with the one knob and press + hold one or more keys on your keyboard.
Is it made with Synthedit? YES! So it’s big, a CPU hog, might crash your host, is NOT available for overpriced MAC computers and is responsible for all the evil in the world (incl. Rave and Facebook).
Drone for Windows (VST) is available as a free download here.
