I decided I’d use multiple 303s and focus on melody and harmony. I also decided to use some polymeter (different parts layered in different time signatures) and a gradual tempo change to undermine the basic 4 4 rhythm and help to keep away from a typical 303 bassline.
I did want to use some of the classic characteristics of the 303, still, otherwise if the 303s were entirely unrecognisable to even the most hardcore nerds it’d seem a bit pointless. So I did use the pitch glide and also tweaked the (virtual) knobs a bit.
I used four copies of a software 303 emulator called AB-303. Three form sparse chords, with the polymeter creating variations. The fourth plays the melody in 4 4.
Then there’s just some drums (also in 4 4) and some effects and that’s it.
