Georg Brandt is a German composer and sound programmer. He started out writing music demos and a drum editor called Rhythm Construction Set for the magazine 64'er and then worked on games for Magic Bytes and briefly Rainbow Arts.

Music Development

Georg said this about his video game music:

In 1986 I wrote my own music engine in 6502 assembler driving the 3 SID channels (i.e. 3 tracks), an optional virtual drum channel (4th track) and an additional sample playback channel (5th track). The engine was IRQ driven to make it in run in parallel to the game play.

The notes were stored in memory in a piano roll style. A simple memory hex editor was sufficient to view and create the song data. Each tracks melody line was described by note height (chromatic note number) and sound type. „Sound type“ was a reference to an internal predefined instrument in my sound engine. I used the note heights byte most significant bit (MSB) to store if the sound was played (meaning “key down”) or in the release phase (meaning “key released”).

Each instrument preset had an ADSR setting, waveform type (rect, sine, triangle, saw), pulse width modulation settings, filter settings and special effects like arpeggios/chords, additional attack noise a.s.o.

The virtual drum channel was routed to a SID channel replacing the melody playing on that channel for the short time the drum sounds were playing.

The sample playback engine simply wrote the sample wave data interrupt driven to the SIDs main volume register. The fact that one could playback a sample like this was rather a side effect and not intended or documented in the SIDs chip design. The samples were created from different audio sources using a DIY digitizer board.

For composing I used a simple JVC Keyboard and then transferred those musical ideas directly to the piano roll style tracks with a simple hex editor. Later I directly composed inside the hex editor.


I wrote music for Magic Bytes, Rainbow Arts and the German C64er magazine.
