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

Plug in. Tune up. Play a chord. If it needs more bite, turn it up. If the low strings need to hit harder, add Pulp. If the top end is getting in the way, move the microphone. Ample Juice works like the rig you already understand, because playing guitar should not feel like programming one. ONE SCREEN, LIKE AN AMP The whole signal path is in front of you: gate, boost, drive, amp, 4x12 and microphone. No pages to remember and no puzzle of hidden settings. Start with the controls you know, turn them until the guitar sits right, and leave the rest alone. FROM CLEAN ENOUGH TO LEAD READY Juice covers the ground between edge-of-breakup rhythm and a full lead voice. The first part of the dial adds body and sheen. The middle is where crunch lives. The last stretch opens quickly for sustain and saturation. Even when the gain is up, chords keep their notes instead of folding into one fizzy block. Pulp sits before the amp, where your boost pedal would. It trims low end before the clipping starts and leans into the midrange, so palm mutes land firmly and down-tuned riffs do not spread across the floor. Throw the Clean lever and the drive section steps aside; throw it back and every dirty setting is waiting where you left it. POSITION THE MIC BY TOUCH OR MOUSE No need to translate what you hear into studio jargon. Put a finger on the mic and move it, or grab it with a mouse. Position it toward the cone centre for cut, toward the edge for warmth, farther back for space, or off-axis to soften a sharp pick attack. The cabinet picture is the control—move what you see and listen as the tone follows. READY WHEN THE RIFF ARRIVES Use it as an AUv3 effect in your host or open the standalone app and choose your interface input. It adds no latency, so the note stays under your fingers. The tuner is already at the front of the rig, presets can save without stopping playback, and every control can follow MIDI or automation. 25 factory presets give you useful starting points for clean, crunch, metal, lead and more. Save the sounds that belong to your songs and take them across your devices.
