The Danish pianist Johannes Bjerregaard created a few hundred SID tunes on the Commodore 64 and is regarded as one of the most brilliant C64 composers of all time. He was active from 1986 to 1990.
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 his tunes in the latest High Voltage SID Collection which was at #65 at the time of publishing this blog post. I noted down 78 tunes I liked and created stereo MP3 files for easy listening here. You could call it sort of “Johannes Bjerregaard’s Greatest Hits” as compiled by JCH.
