Sure thing. Start with a cheap op‑amp board and keep the filter section simple—just one 12‑pole ladder or a couple of cascaded 4‑pole ones if you can manage it. Use a 12‑bit DAC; it’s enough for a punchy envelope and you save on power. Keep the envelope generator to an ADSR with a short decay and a sustain that’s still high. For power, a single 9‑V battery and a low‑drop regulator will cut cable clutter. Use a 5‑pole resonant filter to get that gritty, loud sound without extra components. Finally, put a decent 12‑V transformer‑based preamp in front of the amp to get volume without messing with the synth’s internals. Simple, minimal, loud.

Keep the bitcrusher as a simple 8‑bit right‑shift register; no ADC needed. For the synth‑to‑sampler, just hook the filter output to a 1‑channel line‑level input on a cheap loop recorder or even a smartphone app—no extra hardware. Design everything on a single 4×8 grid PCB, use surface‑mount parts where possible, and order everything in one batch. Stick to one power rail and avoid custom connectors. That way you can breadboard, test, and solder in about two days. Don’t bother with fancy PCB routing; run the traces straight. And remember, if it works, you’re done—if not, just hit the “reset” button.
