Thomas Mogensen, known as Drax in the European C64 demo scene, created almost a thousand SID tunes on the Commodore 64 from 1987 and up. Most of these were composed in my music editor.
SID tunes are chiptunes created on the Commodore 64, or an emulation of the C64 or its SID chip.
The SID chip in the Commodore 64 was quite advanced in 1982. It had three channels across eight octaves, ADSR, four different waveforms, pulsating on the square waveform, three ring modulators, and multi mode filtering. The music players written for it were usually called 50 times a second, quickly changing waveforms and frequencies to simulate vibrato, drums and arpeggio chords.
I’ve been listening through all of Drax’s tunes in the latest High Voltage SID Collection which was at #65 at the time of publishing this blog post. I noted down more than 100 tunes I liked and created stereo MP3 files for easy listening here. You could call it sort of “Drax’s Greatest Hits” as compiled by JCH.
Most of the tunes also have mono MP3 alternatives from SOASC created using a real C64.

You got to love Tristesse from Drax. Such a beautiful one.
Still missing some of my favourites here, like Stories, Rushed Off, Heartless, Focus, Dope Out, etc.
Disco Zax, Overlame, Boneless, heard those in so many demos in the very early 90s, DRAX seemed to rule the demo scene back then 🙂 He was so insanely productive !!!! … well yeah, i’m a big fan of DRAX, more recently, i liked Resolution and Gemini .. Thomas is really the kind of awesome melodies.
Interesting to hear the analog pops in his Thaw tune … that 6581 DC offset modulated by the envelope, i love it 🙂
No heart for Pretence? It’s so freaking beautiful. Drax at his bittersweet best. 🙂
