What's New in Drambo

2.57

October 16, 2026

New: • Added on-screen Pitch Bend and Modulation wheels, including recording, playback, and editing of their automation. The wheels follow automation playback and incoming MIDI, while automation curves update live during wheel and knob recording. • Added Signal Monitor Recorder for capturing audio and MIDI phrases on the fly. Hold an input to open the Signal Monitor, select Recorder, and press REC. Press it again to stop, then drag recorded audio into a sampler or MIDI notes into a clip. Enable SYNC to start and stop recording on bar boundaries. • Added Dual Oscillator with eight shapeable waveforms, five cross-modulation modes (PM, exponential FM, AM, Ring, and Shape modulation), hard sync, phase control, and optional 2x oversampling. • Updated the LFO module with 16 waveforms, from classic shapes to Bounce, Random Walk, and Organic Motion. Each waveform includes a contextual Shape control. Poly Spread can distribute voice phases evenly or create drifting rates independently of gate retriggering. Also includes simplified tempo sync, smooth Shape modulation, and a more compact layout. • Added a new Noise module with nine modes: White (Fast), White / Pink, White Filter, Chip Long, Chip Short, Velvet, Static, Metal 808, and Metal KR55. A compact source for audio and modulation with a mode-specific Color control, optional polyphony, and stereo operation. • Added Buffer Live module, a tempo-synced live buffer effect for looping, scratching, and rearranging audio. Features variable playback speed and offset, rhythmic snapping, feedback routing, Freeze/Record controls, and click-reducing crossfades. • Supersaw Oscillator: added a new V2 mode that closely models the original JP8K supersaw. • Added Multi Envelope. Build custom envelopes using freely added segments, each with Level, Time, and Curve controls. Includes editable Hold, Loop, and Release markers, polyphonic modulation, quantized beat timing, and semitone ranges of +/-12, +/-24, or +/-48. • Added Morph Switch, which stores and recalls parameter states using a polyphonic Index input or MIDI notes. Includes Quantized, Crossfade, Latched Note, and Note Punch modes for note-based parameter locks. Supports smooth transitions, global Amount control, p-lockable state selection, and note-to-state assignment with Copy and Paste. • MIDI to CV now outputs Mod Wheel position and voice number. Improvements: • Doubled automation recording resolution. • Slightly increased the brightness of the default skin. Fixed: • Fixed AUv3 MIDI output handling for mixed-length messages and improved performance with large MIDI packets. • Fixed navigation arrows disappearing with long wavetable filenames in Wavetable Oscillator, Wavetable LFO, and Wavetable Waveshaper. • Fixed MIDI CC64 sustain pedal events handling. Visual Extension IAP: • Added Visual Processor Switch under Visual > Processor > Utility. Switch between processing chains using buttons, CV, or MIDI, with optional live crossfades. All layers share a single Frame input, while empty layers act as bypass. Only active processing chains run, keeping processing efficient. • New visual presets • Fixed camera issues on 7th-generation iPads.

HIGHLY RECCOMEND

I'ts the most powerful, fast and unique app I have ever come across, it can sequence, patch modules in flexible ways easily for deep sound design possibilities and now it even does visuals. Truly incredible and powerful, I have been using it constantly since I found it a few months back

Despite cases full of eurorack

Despite couple of cases of eurorack i never thought i would have so much fun with an ipad app. I am still learning and figure the whole thing out, but i love it so far. The workflow is top notch👍

Best Create your own synth/effect toolbox

If I had to pick one synth to have on a desert island it would be Drambo no contest. 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

Great but new features are charged for.

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!
