Video: Lesson P20 - Sound on the Sam Coupe

The Sam Coupe had pretty powerful sound! With 6 tone channels, 2 Envelope Generators and 2 noise generators, The SAM has really decent sound capabilities!

The Sound chip has 32 registers... to change one, first we OUT the register number to port 511... then we OUT the new value to register 255

Thanks to these tutorials, I've ported over a few of the ZX Speccy 1-bit music tunes to run on the Sam Coupe emulator 'sim coupe'. These are sitting here as disk images, that will then need to load in the binary music files.
Due to the Sam's 6mhz speed, the tunes are quite a bit out, but, it was the challenge of getting them to simply work on the Sam Coupe that inspired me to do this. Even though some sound garbage. Requires much more knowledge than I have to dig down deep and to carefully tune the inner engine's looping by counting clock cycles everywhere. A bit too much for me.
Could not have acheived this without the Sam tutorial!

Anyway, tunes are here : https://github.com/bushy555/Sam_Coupe_1-bit_Music
