Fire

Fire — Polyphonic 6-Operator FM Synthesizer

Fire is a polyphonic six-operator FM synthesizer built around all 32 classic algorithms from the Yamaha DX7. Each operator features high-quality wavetable sine generation, self-feedback, and classic FM four-stage envelopes (R1/L1–R4/L4) with velocity sensitivity, delivering the FM palette — electric pianos, organs, brasses, strings, metallic textures, and beyond — in a modern, approachable workflow. 99 factory presets are included.

Features:

• 6 operators per polyphonic voice — each acting as carrier or modulator depending on the selected algorithm.
• All 32 classic FM algorithms as featured on the Yamaha DX7.
• High-quality wavetable sine generation with linear interpolation and self-feedback per operator.
• Classic FM four-stage envelopes (R1/L1–R4/L4) with velocity sensitivity on every operator.
• Per-operator control: frequency ratio (0.5×–16×), fine detune in cents, output level, feedback amount, and velocity sensitivity.
• Global LFO with 5 waveforms (Sine, Square, Saw, Triangle, Sample & Hold) targeting pitch, level, or pan — free-running, mono retrigger, and poly retrigger modes.
• Global effects chain: Phaser (2–12 stages), Chorus, stereo Delay with independent L/R times, and Reverb with pre-delay and damping.
• 5-band parametric EQ with interactive visual curve.
• Compressor with real-time metering and gain reduction display.
• Interactive visualisers for operator envelopes, LFO waveform, EQ, and compressor.
• Virtual on-screen keyboard — no MIDI controller required.
• MIDI CC support (CC 74, 71, 73, 72, 7, 10, 5, 1, 64) — fully DAW-automatable.
• 99 factory presets: electric pianos, organs, strings, brasses, metallic textures, and more.
• Full preset management: save, load, delete, undo/redo.
• 16-voice polyphony with portamento/glide, pitch bend, and mod wheel.
• VST3, AU, and Standalone.
• macOS 10.13 (High Sierra) or later · Windows 10 or later.
• Single-user license · Activate on up to 2 computers.
