"Bärnsten" (Swedish for "amber") is the result of an experiment I made a couple of years ago. I created some sounds on the C64, sampled them using an 8-bit sampler, and mixed them with some drum loops using a multi-channel tracker on the Amiga. Read more.

Carol of the Bells

This piece, Shchedryk, was written by Ukrainan composer Mykola Leontovych in 1916, as an assignment for a harmony course. The ostinato is an ancient new year's chant. Peter Wilhousky wrote the English lyrics in 1936, transforming the song into a Christmas carol. Read more.

It struck me that, at least in theory, organ pipes should generate quite primitive sound waves. If so, how come a church organ doesn't sound like a chip tune, which is also built up from simple waveforms? Well, actually it will, if you remove the church. And if you connect a Commodore 64 home computer to a loudspeaker in a large hall, it will sound like an organ. Read more.

The hardware chiptune project

Normally, when you create a chiptune, you start with an existing chip (such as the SID chip or the YM2149) and write a tune for it. We decided to start from scratch, and create a chip and a tune. Read more.

Triple fugue #1

When Frédéric Chopin wrote his rather melancholic prelude in C minor, he did not know that years later, a computer game called Ghosts And Goblins would carry the chord progression of the first few bars of that very prelude into the hearts and minds of a whole new generation. Read more.
