NuSaw is a polyphonic SuperSaw synthesizer: the huge, detuned '90s dance sound, built for accuracy and tuned to fill the room. At its heart is a stack of 3 to 25 detuned sawtooth oscillators with a sine sub, a resonant lowpass filter, and dual ADSR envelopes for amp and filter. On top sits a full effects chain: an accurately modeled chorus, a tempo-syncable stereo ping-pong delay, plate reverb, and drive. Motion is built in: three LFOs, a flexible modulation matrix, a sequenced gate, and an arpeggiator, so patches breathe, wobble, all on their own. • 50+ factory presets: leads, basses, stabs, pads, strings, arps, and keys • Authentically modeled SuperSaw engine with accurate drift and stereo spread • FX rack with authentic chorus + ping-pong delay + reverb + drive • 3 LFOs, mod matrix, sequenced gate, and arpeggiator • Resonant switchable filter, with slope control and key tracking • Save and share your own patches • AUv3 plug-in for AUM, Logic, GarageBand, Cubasis, and more, plus a full standalone app with an on-screen keyboard Whether you're chasing a festival trance lead, a snarling Reese bass, or a wide evolving pad, NuSaw gets you there fast.

PX1 is a dual-engine FM synthesizer inspired by the classic 6-operator digital synths of the 1980s. Each engine features six operators, 32 algorithms, and full envelope control — giving you everything from glassy electric pianos and punchy basses to evolving pads and metallic bells. What makes PX1 special is the dual-engine architecture. Two completely independent FM voices run side by side. Copy one engine to the other, make subtle changes, then use the Spread control to place them across the stereo field. The result is a lush, wide sound that a single FM engine simply cannot produce. FEATURES • Two independent 6-operator FM engines • 32 classic FM algorithms • Per-operator envelopes (4 rates + 4 levels) • Per-operator pan for detailed stereo placement • Five macro knobs — Brightness, Touch, Attack, Decay, Spread • Copy/Paste between engines for instant layering • Random patch generator exploring the classic FM sound palette • Built-in reverb (Size, Damp, Amount) • Mono, Legato, and Portamento modes • LFO with triangle, saw, square, and random waveforms • Pitch bend range and transpose controls • Key velocity sensitivity per operator • Keyboard rate scaling and level scaling • Operator Key Sync on/off for consistent or organic attacks AUv3 PLUGIN PX1 works as a standalone instrument and as an Audio Unit v3 plugin. Load it directly inside GarageBand, Logic Pro, AUM, Cubasis, or any AUv3-compatible host. Full parameter automation is supported — record knob movements in your DAW and play them back. DESIGNED FOR MUSICIANS The interface stays close to the original FM programming model that experienced synthesists know, while macro controls make it approachable for anyone. Turn one knob and shape the entire sound; dive into individual operators when you want surgical control.
