It's the sound quality of the modules that really matters, and Audulus sounds fantastic.

Features

A node for every need

Audulus processing nodes are diverse, powerful, and easy to use, with no hidden controls.

Control everything with MIDI

Control Audulus with your MIDI controller keyboard or control surface.

Polyphonic processing

Process multiple voices. Have precise control of when voices are mixed into one.

Build new custom nodes

Group existing nodes to build new nodes. Reuse entire networks of nodes. Even define custom user interfaces for your nodes.

Modulate anything

Connections can be made to any knob so you can modulate any parameter. Nodes are optimized to handle extreme modulation.

Round-trip workflow

Begin a patch on your iPhone while on the go. iCloud automatically syncs it to your iPad or Mac.

Live patching

Make connections while processing audio. Audulus will fade connection changes so you won't hear any pops or have sudden modulations.

An Audio Unit for your studio

Use Audulus inside Logic, Garage Band, Ableton Live, or Digital Performer. (Mac Only)

Multitouch interface for iPad/iPhone

Multitouch connection gestures. Pinch to zoom.

Finally.

An advanced modular on a mobile platform.
