I’ve gotten the scan line to finally work, its sorta complicated but it scans the line its on for any blocks and each individual block of the scan line is a specific row a notes for example all of the notes on 0x is middle C so the scan dot of the scanline on 0x checks if theres a block there and it doesn’t even need to know what note it is all it knows is all the notes there are a middle C so it plays a C my next thing to tackle is how to make it play chords as i said earlier the 65mhz CPU can only play a single tone at a time
