VXN2 is the next-generation Vulpus Labs synth, currently in its design phase. No download is available yet.
Design premises
- Operator-based oscillator architecture — DX-style operators, stack-detuned to enable hypersaw-type voicings without wavetable cost.
- Fixed-point phase accumulation — Q32 phase, free wraparound, zero drift.
Float past the phase boundary (filters, envelopes, mixing stay
f32). - Approximated sines, not table lookup — a Bhaskara+Moser polynomial (5 mul + 2 abs + 2 add), branch-free and well-vectorised. THD ≈ −59 dB, masked under hypersaw detune; a higher-accuracy path is reserved for solo carriers.
Architecture decision records are forthcoming.
