Thomas Egeskov Petersen, known as Laxity in the European C64 demo scene, composed more than 200 SID tunes on the Commodore 64 from 1987 and up, most of them in his own music player.
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 Laxity’s tunes in the latest High Voltage SID Collection which was at #65 at the time of publishing this blog post. I selected more than 180 tunes I liked and created stereo MP3 files for easy listening here. You could call it sort of “Laxity’s Greatest Hits” as compiled by JCH.

Great! “Zimxusaf I” is one of my absolute favourites – I wonder what the title means though ??! 🙂
Never heard “Fairly Green” before – shows me that Laxity is the jazz master 😀
