What is a KC file?
A KC file is a KeyKit Collection used by Tim Thompson's KeyKit. It contains a set of named musical sequences you can play in KeyKit. KC files are most often used to group similar percussion sequences into collections that can be opened and played using KeyKit's Blocks tool.
KeyKit is an open source programming language and graphical interface used to create MIDI music. Developer Tim Thompson created the language and accompanying program in the 1990s, during the time he worked at AT&T. While KeyKit was originally released through AT&T, it is now available for free from GitHub.
KeyKit was developed for use on Windows NT, but still works on modern Windows, Linux, and Raspberry Pi systems. So if you have a KC file sitting on your computer, you can still open it and play the musical sequences it contains using KeyKit. Additionally, KeyKit comes loaded with a number of sample KC files, including rock-, jazz-, rap-, funk-, and reggae-inspired collections.
