Besides what Lugia said you could maybe build a single mono synth voice in this case. You already have a basic sequencer and a dual vco plus LFO. So you might want to start „east coast“ and add two envelopes (imho Maths is too big for your case), vcas, a filter and are ready for some bleeps and bloops. Possibly you even have some space left for later additions.
Maybe you could also go west and add something like Happy Nerding FM Aid or some Waveshapkng utility and a Low Pass Gate (LxD) plus some envelopes and vcas of course.
