I make this music myself. Old school synthesizer composing. Inspiration comes from classical music and famous artists like Jean Michel Jarre.
I perform on my own. Mostly live play using sequencer and Line In recording on computer. Occasionally, I re-master and mix a little but not often.
Songs that have many instruments take time and effort since I play them all, one at the time, then put it all together with computer software like Renoise and Cool Edit Pro.
