"Drambo changes the face of iOS music apps." Cult of Mac Drambo is your all-in-one sound laboratory that adapts to your workflow: build beats as a groovebox, design synths, or transform audio with effects, standalone or inside your favorite DAW. At the core of Drambo is a fresh approach to modular design that makes creating with modules easy, fun, and accessible. Connections happen automatically as you add or move modules, so there are no messy cables to slow you down. The interface adapts to your workflow, generating modulation controls when you need them, and even lets modules contain other modules for perfect organization. You’re always free to override the automatic connections, but most of the time, you can just dive in, experiment, and shape sounds without getting tangled in wires. Use a deep and innovative sequencer to compose patterns and whole tracks, for production or live performance. Go beyond simple looping sequences with parameter locking, conditional step components, parameters automation and powerful scene morphing. Drambo works equally well as a self-contained standalone app or audio unit plugin with audio and MIDI connectivity as an AUV3 instrument, audio effect and MIDI effect. You can use Drambo as • A Complete Studio: Produce entire tracks and perform live in a self-contained, multitrack environment. • An Endless modular playground, that allows you to build, modify and store custom instruments and effects. For instance: build a custom synth, sample and resample, build a Theremin using a gyroscope module, or turn your table into a playable surface, by processing microphone input with physical modelling modules. • An Advanced MIDI Sequencer: Control hardware or AUv3 instruments. Generate custom MIDI CC messages or send modulation signals to physical modular synths via DC-coupled interfaces. • The Ultimate AUv3 Plugin: Load Drambo inside other DAWs as an instrument, audio effect, or MIDI processor. Replace dozens of standard plugins by building your own complex modular delays, reverbs, decimators, or modulators in seconds. • A Unified Audio-Visual Studio (Drambo Visual IAP): Arts united. Step into another realm of modular visual synthesis to build complex generative video art, or seamlessly patch your audio and visual engines together for deeply integrated performances. Features: • Polyphonic, stereo processing and audio-rate modulation. All signals are equal. Up to 16 voices per modular instrument rack. • Unique modular concept: cable-less, drag'n'drop, color coding dynamic interface, automatic connections, and customizable compact, rack views. • Directional flow makes Drambo routing and patching straightforward. Signal flows only left to right, so there are no instant feedback routings in Drambo. Delayed feedback is possible using certain modules. • Simple and clean interface, that scales to every size and device orientation • Over 140 modules available, such as: oscillators, samplers, physical modelling modules, LFOs, envelope generators, filters, audio effects, mixers, MIDI processors, sequencers and math functions. (Includes a macro oscillator based on the famous Eurorack Plaits module, with 24 synth engines) • Custom modular racks that can be nested, with presets at the track, rack, and module level. • Clip launcher / song arrager. • 16-tracks, polyphonic sequencer with parameter locks, automation and step components. 8 dedicated step sequence editor types, piano-roll, powerful automation designer with drawing modes and cubic Bezier curves. • Audio Units hosting ( standalone app only ) • Morph groups: you can morph many parameters using a single slider. • Available as a standalone app, AUv3 instrument, effect and MIDI effect. • MIDI and Ableton Link support Drambo is all about control. Control things that other apps don’t even give you access to. Visit the BeepStreet page for help and tutorials, and Patchstorage for community content.
