Shaper - Synthesizer for iPhone

Product Snapshot

Shaper is a subtractive synth built specifically for iPhone, designed to give musicians a compact yet capable tone-design tool. It combines two alias-free waveform oscillators, a dedicated noise generator, and a compact modulation set (two envelopes and two LFOs) to produce everything from warm basses to aggressive leads. The layout is streamlined so sound design feels fast and intuitive on a small screen.

Sound Engine Details

• Two high-quality, alias-free oscillators plus one noise source for texture and grit.
• Dual envelope generators and a pair of LFOs for shaping amplitude, pitch, and timbre over time.
• An authentic-sounding analog-style filter to sculpt harmonic content.

Modulation and Control

• AUv3 support for automation and integration inside hosts like AUM, Cubasis, and GarageBand.
• Full MIDI functionality, including MIDI Learn for quick controller mapping.
• Drag-and-drop routing for assigning modulators to destinations without menu diving.
• Advanced LFO editing with fully customizable graph shapes for complex modulation patterns.

Effects and Signal Flow

• A three-slot effects chain that lets you stack processing modules in flexible orders.
• A collection of eight onboard effects — examples include bitcrusher, chorus, and reverb — to decorate or destroy your sound.
• Routing and effect ordering designed for on-the-fly experimentation.

Interface and Workflow

• A concise, phone-friendly UI that groups related controls together so common tasks are fast.
• Workflow focused on tactile operations (touch-and-drag) to keep creativity moving on small displays.

Compatibility and Integration

• Works as an AUv3 instrument for use inside compatible iOS hosts and supports host automation.
• Full MIDI compatibility with MIDI Learn, so hardware controllers can be mapped quickly for live or studio use.

Suggested Alternative

If you’re mainly after portable audio playback rather than synthesis, consider eSound — a free MP3 music player that’s highlighted here as an alternative option for casual listening needs.
