W.I.P. for now
Daft bouncy thing that could probably use a bit more variety, if it weren't so simplistically dense already. Here's how to cheat with a guitar (get in charity shop): I fumble around finding the chord, strum it to the beat for a bit, repeat; then cut out the silence in editing. Hey presto, "competent" rhythm guitar! It certainly beats using 1 bar loops or VSTs which sound fake (which has its own uses too ofc).
I once recorded me singing a scale pre-balls dropping, so that makes a fun Mellotron-esque .SFZ instrument.
