What Drambo is

Drambo is a modular groovebox and audio-processing environment for building synthesizers, sample-based instruments, and effects. Its library contains over 150 modules, from oscillators and samplers to filters, modulators, effects, and sequencers. Modules connect as you add or rearrange them, with the option to change those connections. The sequencer supports parameter locks, conditional step logic, automation, scene morphing, and patterns up to 256 steps. Audio processing includes stereo polyphony with up to 16 voices and audio-rate modulation. Drambo runs standalone or as an AUv3 instrument, effect, or MIDI effect; the standalone app can also host Audio Units. The Mac version works in AUv3-compatible DAWs, including Ableton Live and Logic Pro. MIDI controller profiles and two-way communication can reflect project state on supported controllers. It is available for iOS and macOS, requiring iOS or iPadOS 15.6 or later, or a Mac with Apple silicon. Optional Drambo Visual adds modular graphics, audio-reactive visuals, HDMI display performance, and synchronized audio-video export.
