AcidBath

TB-303 Voice

A complete TB-303-style voice in Eurorack. WDF-modeled diode-ladder filter, accent circuit, slide circuit, and square/saw oscillator — all the squelch, none of the eBay tax.

What It Does

• TB-303 voice path: VCO → diode ladder VCF → VCA
• Accent + slide circuits modeled at component level
• CV in for pitch (V/oct), gate, accent, slide
• Audio out at eurorack level

Why It Exists

303s sound the way they sound because of how the filter, accent, and envelope interact. AcidBath models that interaction circuit-accurate so it squelches like the real thing — and lives in your rack instead of on your desk.
