not at all puredata only,
but the electric bass sound is a shitty patch i made that have problem handle polyphony
and some layers that comes time to time is from another patch i found, compo environment is energyXT and puredata is used as VSTi via the pdvst thing, other vsti for the rest of the sounds.

Cool. Nice old skool funkadelic synths, and it's got structure. I like the litte touches like reverb on some beats and some going backwards like a turntable scratch. Beats are a bit skippy for my taste, the timing wanders but it gives it charm, but the overall vibe is really sweet. When you say "electric" bass do you mean that moog sort of bass? It's not shitty, it's really good pulse+saw bass, kinda like a Oberhiem or memorymoog and don't worry about poly on that, it should be a mono bass anyway.
