About PX1 FM Synth
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.
