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
