The Guitar Tuner

Download: (zipped .prg)
Requirements: Any Vic-20.

This program helps you to tune your guitar. Press keys 1-6 (or e, a, d etc) to make one of the strings sound. Listen, compare and tune your guitar accordingly. Pressing a key for a string that already plays makes it stop. The first version was for PAL only. This one should work on NTSC as well. It's actually more accurate on NTSC, but that has only been tested in VICE.
