MESA is a wavetable synthesizer unlike any other — it turns visuals into sound. Drop in a shader or a .vkograph and MESA renders it offscreen, reads the light across the image, and turns that into a wavetable you play. The picture literally becomes the oscillator — and the same visual keeps living behind your keys, reacting to every note. No other synth works like this. Behind the magic is a complete, serious instrument: THE ENGINE • 64-frame wavetables, FFT mip-banked for clean, alias-free playback everywhere • Unison oscillator stack with detune, spread, and a sub-oscillator • Zero-delay-feedback filter — cutoff, resonance, drive, self-oscillating • Full ADSR envelope, portamento glide, and a dedicated pitch envelope SHAPE THE SOUND WITH LIGHT • Vision panel: choose the scanline, weight color channels, bend the brightness curve, sweep time — one shader, a thousand timbres • 33 color palettes that reshape the tone, not just the look • VFX chain: 26 stackable visual modifiers, each one also an audio effect A FULL STUDIO • 3-slot modulation matrix with 2 LFOs, velocity, and mod wheel • 8-stage stereo FX rack: tape, wow & flutter, chorus, delay, reverb, lo-fi, tape-stop • Sampler mode — load any audio, auto pitch-tracked across the keys • Arpeggiator, Ableton Link, and MIDI Learn on nearly every control BUILT FOR YOUR WORKFLOW • AUv3 plug-in AND standalone app — one purchase, iOS + macOS • iCloud sync — build a patch on your Mac, it's ready on your iPhone • Categorized preset browser with import/export and full patch recall

Seyfert is a delay unlike your others: every echo spawns at its own place in an orbit around you, and the whole constellation slowly revolves. Turn up Feedback and you don't just add repeats, you spawn more echoes into the orbit, from a single tight slap to a dense, spiralling cloud. Spin revolves the whole field around you. Doppler bends the echoes in pitch as they whirl toward and away. 3D wraps them around your head on headphones. Lift the repeats an octave into crystalline shimmer, drop them a sub-octave for weight, or detune them into a chorus. A lush reverb blooms around the echoes, never the dry signal, so your source stays clear while the repeats dissolve into space. Features: - Orbital echoes, where Feedback sets how many circle you - Spin, from a gentle drift to a full whirl - Doppler pitch-bend as the orbit turns - 3D binaural imaging for headphones - Shimmer and transpose, up or down one octave (octaves, fifths, sub-octaves) - Per-echo Trail tone, tape Wobble, and Drive - Lush reverb applied to the echoes - Full 5-band EQ on the wet signal - Orbit and Ping-Pong patterns, tempo sync - 18 factory presets, plus save your own - Standalone app and Audio Unit (AUv3) for GarageBand, AUM, Logic, and more No accounts, no tracking, no data collected. Everything stays on your device.
