30 modular systems in a multi-instrument and sequence designer
Quadra Modular is a powerful 4-part multi-instrument and sequence designer, ideal for the creation of dynamic, rhythmic, and evolving sequences utilizing an incredible selection of patches created on a wide range of modular synthesizers, from vintage to modern, stand-alone to fully customized and purpose-built systems. We approached recording these beasts as if they were acoustic instruments, creating discrete velocity layers and round-robins in order to capture their organic soul.
Quadra is a versatile instrument, capable of a wide range of sounds and uses from standard fare instrumentation to evolving, complex, and adaptive progressions and harmonizations that can be morphed and performed in numerous ways to suit the needs of your production. With a masterful selection of hundreds of professionally designed presets, Quadra offers incredible sound quality and near endless inspiration on-demand.
Quadra leverages a powerful instrument selection, deep factory library, focused and intuitive workflow, and expressive performance controls to deliver cinematic sound quality and near endless musical inspiration.
Curated Instrument Selection
Quadra provides 4 robust instrument layers that can be used together to create striking and evocative performances. Each layer can be assigned from a selection of 30 multi-sampled sources including massive stand-alone systems like the Colossus, to popular small format systems like eurorack.


At the heart of each of Quadra's instrument layers is a powerful, multimode 64-step sequencer with MIDI effects, allowing you to quickly add rhythmic grooves, create arpeggiator sequences, add harmonies, and even quantize the incoming notes to specific scales. Choose a global rate, gate length, and max velocity, then customize your sequence with per-step velocity, link, harmonization, pitch offset, octave offset, gate, step repeat and panning. Save your patterns to disk as presets to share, or use the handy "copy-to" button to quickly duplicate your finished sequence from one layer to another.
Quadra includes a number of MIDI effect modules that allow you to embellish and augment your sequences in creative ways, including Euclidean Emphasis which adds rhythmic accents, MIDI Delay, Random, and Pitch Drift which enrich your sequence, and a scale quantizer that allows you to snap all notes to a scale of your choosing. You can even drag-and-drop the modified sequences as MIDI into a track of your DAW.
