this is a sad little SID thing
i got a bit dismayed at my efforts in the vic20 category which i never even started writing music for, but i did make some interesting tools and feel more confidant with my assembly skills (continue that project for Winter Chip?)
so i jumped on the SID wagon, read the specs for about an hour -- funny thing how much i instantly understand after years of being into modular synthesis -- i wanted to unlock the things i know now
so i opened Goat Tracker and discovered it doesn't support the 11bit values for the filter cutoff?
really... i just wanted to explore sounds but i failed to capture a lot of them since i was editing tables while the pattern looped... i think goat tracker is a decent tool for writing songs, but not necessarily for exploring and expirementing with the SID (i didn't even get to syncing and ring modding SAD )
maybe SID something more exciting in the futre
