Up for some hardcore music nerd action?

Developer Linus Åkesson, creator of the Commodordion 8-Bit Commodore 64 accordion synthesizer, shared this video, demonstrating live coding for music on the Commodore 64. After demonstrating C64 command-line music coding, he wraps things up with a chiptune jam.

Video Summary:

“In this video, I make 8-bit SID music on a Commodore 64 without any software apart from the built-in BASIC interpreter. This involves poking numbers into memory and hardware registers and writing machine code in decimal.”

Topics covered in the video:

0:00 Introduction
1:57 Groundwork
8:50 Time and pitch
13:23 Interactive editor
17:11 Note on/off subroutines
