"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.

I recreated just about every synth patch from other stuff with Drambo and the ability to fiddle with any connection however you want leads to so much creative possibilities. I was initially intimidated but once you get over the first hour it’s hard to really go back to anything else with this level of power, quality and flexibility. D ### 3/5 — Great but new features are charged for. *2026-08-16* Great software but really not on board with the developer adding new features like granular engine and other dsp features and charging extra for it when they should be part of an upgrade cycle… does Ableton do this? No… not on board with these tactics and making me not want to use the app no more… instead of updates with added new features… we keep getting in app purchases all the time! Not cool! **Developer response:** Thanks for the review. I understand the concern, but Drambo has been in continuous development for about 5 years, and a large number of new modules, features and improvements have been added for free during that time. There are only a few DSP IAPs, they cost $4.99 each, and each one includes multiple modules/features. The main app is still $24.99, which I’ve tried to keep very affordable for what Drambo offers. The occasional IAPs are not meant to replace free updates. They help make continued development sustainable. After 5 years, without some additional revenue, I simply couldn’t keep developing and supporting Drambo indefinitely. I know this model won’t suit everyone, but I think it’s a fair way to keep Drambo growing without turning every new feature into a purchase. ### 5/5 — Drambo rules *2026-08-04, version 2.54* It’s the best, as indispensable as AUM ### 5/5 — Impressive *2026-08-01* Amazing powerful modular groovebox… it seems unlimited in possibilities, A mix of Ableton, nord modular, and Digitakt and even much beyond thanks to AUv3 support.Though mastering it certainly comes at a certain cost in time invested.. would maybe wish some better sound & preset browser (categorization, flagging, instru preview) and color theme customization though. Long life to this incredible app ! ### 5/5 — Unglaublich gut *2026-07-11* Wer einen Synth sucht, der alles kann, kaufe sich Drambo und ein ios device. Wer eine einzige App für elektronische Musik kaufen will, greife zu Drambo. Die innovativste, umfangreichste, mächtigste und flexibelste ios Musikapp. Dass nun auch noch live visuals dazukamen, lässt viele Desktop Marktführer mit Abstand zurück. Großartig. Bravo und vielen Dank!!! ### 5/5 — My bad *2026-06-22* My last review was caused by my ignorance. This is a fine app and developer. ### 5/5 — 控えめに言って最高！！！ *2026-06-22* 何故いままでこのアプリを知らなかったのかと悔やまれるほどにいい！ 概要はモジュラーシンセとdawシーケンサーを合わせた感じ。 abletonライクなインターフェースで凡そ触っているだけで理解できる。 音源、シーケンサー、どちらをとっても扱い易く、それでいて安直な物ではなく高機能、凡その事を満たしている。しかし基本的にはdawではなくモジュラーとシーケンサーなので、オーディオはサンプラーでの扱い。 アプリで言えばmi rackのような見た目にまんまモジュラーのような物は、モジュラー弱者として難解。sanvoxは音源は最高だがシーケンサーがトラッカーの為扱い辛いら。 zenbeatsはdawっぽい事殆どできてしかも安いけど、なにか物足りない。 gadgetはコンセプト強めで、自由度が無く窮屈さを覚える。 そんな時にdramboに出会って最高か！っていう。 個人的にシーケンサー部で気に入っているのは、ステップシーケンサーの時に、ボタンの数をトリプレットにできる事。fl studioなんかではトリプレットはピアノロールで打ち込むしかなかったが、こちらではステップシーケンサーとピアノロールでグリッドがリンクしてくれる。 発売されて数年経つのに、何故日本語の情報がこんなにも無いのか不思議なくらい。 もっと日本でも知られるべきアプリ！ まだ少ししか触っていなけどアプリのデザインとして気になる事は今の所ない。 強いて言えば挙動が不安定、ファイル管理が不自由、あとはフォーラムでも話題になっているUndoが殆ど役に立たないとか。しかし、そんな事は度返しにして、最高なアプリだと思う！ ### 5/5 — This is the coolest music app ever *2026-06-21* I’ve used A LOT of music apps, easily a hundred or more, and worked with developers on several of my favorites like Audulus 3 & 4 and Elastic Drum, this is hands down the most powerful and fastest music creation app I’ve used, it’s like a modular synth meets ableton, I keep finding more reasons to love it every time I use it, I just discovered the crossfader modulator, everything has been somehow intuitive enough that I figured it all out on my own, and idk… I’m just blown away by how much it can do. If I had one suggestion - make the loop sample / slicer default to having time stretch on, and add transient slicing for the offset so that a drum break or melodic loop can be quickly re-sequenced into new sequences, reference the ableton simpler slice mode Amazing work from my favorite developer 🫶🏼 ### 2/5 — nickle and dime *2026-06-19, version 2.53* all the wave form tunables are hidden behind IAPs and this isn’t made clear before purchase, ### 5/5 — Incredible App! *2026-03-27* Drambo has revolutionised my music creation. It can do so much. I use it as a super advanced MIDI processor for my studio. It’s unique and wonderful, words can’t really explain how good it is. There’s a learning curve. It’s absolutely worth doing, you get so much out of it. The Dev is also a friendly and helpful guy! ## Frequently asked questions about Drambo ### What is Drambo?
