Marco is a powerful 4-oscillator synth built around dual hard sync, with independent shaping on every oscillator. Randomize to spark fresh ideas, then tweak to shape them - a fast, tactile workflow made for finding your own sounds, not just recalling presets. Marco is a new kind of synthesizer built around three breakthrough ideas: • Dual Hard Sync - two parallel hard-sync chains running side by side • Four oscillators, each with its own signal shaping path • Intelligent randomization and tweak system The result is shimmering harmonics, screaming overtones, and evolving timbres no other iOS synth can give you. Whether it's your first synth or your fortieth, Marco meets you where you are. Hit the dice for an instant new sound. Cycle through every valid Dual Hard Sync combination with one tap. Or dive deep into per-oscillator sound design when you're ready. DUAL HARD SYNC • Two parallel hard-sync chains - A, B, or free per oscillator • One-tap cycling through every valid Dual Hard Sync combination • 10 Signature presets built around Dual Hard Sync FOUR INDEPENDENT OSCILLATORS • Waveforms: sine, triangle, saw, ramp, pulse, noise • Filters: LP 6/12/18/24, BP, HP, Notch, Formant • Envelopes: VCA + Filter, linear or exponential, drone mode • LFOs: filter, volume, wavefold, pitch - with phase, reset, fade and clock sync • Glide: exponential, linear, log, S-curve, legato • Master FX bus with drive, compressor, delay, reverb, stereo width and limiter • Hard sync and wavefolding • Link envelopes, filters, LFOs, glide or effects across oscillators when wanting traditional shaping • Monophonic sounds usually only possible in large modular setups INTELLIGENT RANDOMISATION • Musical preset generator - usable sounds, not chaos • Generate by style: Mild, Wild and Recipe • Target by category: Bass, Lead, Pad, Keys, FX, Drone • Tweak system for subtle, context-aware variations • One-tap dice button for instant inspiration EFFORTLESS WORKFLOW • Consistent UI across all four oscillators • Per-oscillator scopes with live visual feedback • Live LFO indicators on every modulated parameter • Expressive XY pad • Built-in keyboard on iPad standalone BUILT FOR REAL MUSIC • 100+ presets, including 10 Signature sounds • Preset import / export • Master Preset import / export • Deep MIDI: full Note + CC mapping (CC mapping AUv3 only) • Dedicated MIDI for Random Generate, Tweak, Dual Hard Sync Cycle, Scope, Preset Browser, XY Pad (AUv3 only) • Clock-synced LFOs lock to host tempo • AUv3 plugin - works in AUM, Loopy Pro, Drambo, Logic Pro, GarageBand, Cubasis and more • Built-in song player with public domain tracks (standalone only)
