PX1 FM Synth vs AD

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.

We rebuilt the legendary micro composer of 1983, then gave it everything the original owners wished for: eight voices, MPE, a sequencer worthy of the name, and a couple of new dirty tricks. The voice is the one you know: a single fat oscillator with sawtooth and pulse (manual, LFO, or envelope PWM), a three-mode sub oscillator, and a noise source, mixed and driven into a classic four-pole lowpass filter. One snappy ADSR, switchable env/gate VCA, and an LFO with triangle, square, stepped random, and noise shapes, complete with onset delay, tempo sync, and retrigger. Portamento with the proper on/auto/off modes, and gate, gate+trig, and LFO trigger modes, exactly like the hardware. And the a sequencer: eight patterns of up to 64 steps, drawn right on the panel, with accent, slide, and octave per step, follow actions and repeats, swing, and tools to randomize in a key and scale, mutate, copy, and rotate. Play a pattern from a held key, transpose it from the keyboard, lock it while you browse presets, and run it from its own clock, the host transport, or an Ableton Link session in the standalone. Sequences save with your presets. • Eight-voice polyphony, or the original mono behavior with the flip of a switch • MPE support with per-note pitch bend and pressure, four aftertouch destinations (VCO mod, VCF mod, filter freq, LFO rate), and adjustable pressure smoothing • MTS-ESP microtonal tuning, retuned continuously while notes sound • SPREAD for stereo voice panning, and AGE, which drifts each voice like forty-year-old components • A full drive section: pre-filter saturation, filter drive, post-VCA distortion, and a tilt EQ • Velocity to filter and amp • A chicklet keyboard with latch and octave shift, playable right on the panel • Full preset manager with favorites and a factory bank • Five faceplate colors, including one for console cowboys • AUv3 and standalone, with an interface that fills whatever window your host hands it AD-202 works everywhere iOS makes noise: AUM, apeMatrix, Logic Pro, GarageBand, Cubasis, and any other AUv3 host, plus a standalone app with its own audio and MIDI settings, Ableton Link, and background audio.
