How it works
saves notes and the sequenz to execute them in the hardware and with the clock input adjustet to the note frequency and and the duration counted with it the chip should be able to play a part of the imperial march and never gonna give you up
How to test
set the clock to 50MHz and a switch at input 0 and 1 (to switch songs and pause) connecting a buzzer to out zero should result in a looping song beeing played
