What's New in Drambo

August 28, 2026

- New MIDI Generative Sequencer module - Generates melodies and voice-led chords within a selected scale. Includes separate trigger and pitch loops, controlled variation, velocity, legato and polyphony. Generated sequences can be copied to the current clip. - Pattern time signature: numerator range extended to 16. - Improved knob interaction reliability on iPad and Mac: reduced accidental tap/double-tap actions while keeping parameter editing and automation recording immediate. Important; needs testing. - Fixed sample-rate-related pitch inaccuracies in Flexi Sampler stretching, Wave Scanner playback, and Looper audio restored from automatically loaded projects. - Fixed misaligned MIDI Learn overlays in the Scene Morph panel. - Fixed a rare crash in the Spectral Filter module. - Fixed a rare crash in the curve editor while recording automation. - Improved incoming MIDI clock transport synchronization. Drambo Visual extension (IAP): - Added MIDI Texture Scanner – turns visual textures into MIDI notes by scanning a line, ellipse, or circle. Map path segments to a custom scale, use the bipolar brightness threshold to trigger notes from light or dark regions, and monitor activity directly on the texture. - Added Visual Mute, a utility that can disable visual processing manually, via modulation, or by following its track’s mute state. - New presets in Shader/patterns, XY Transform/Projection and Processor Shader/Feedback and FX - Fixed: Scene, beatTime() variable was not updated properly. DSP Extensions 1 (IAP): - New Spectral Delay module - Shape delay time across the frequency spectrum to create rhythmic echoes, stereo movement and evolving textures. Includes tempo sync, quantization, feedback, diffusion and Hold.

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!

Response from developer

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.

Drambo rules

It’s the best, as indispensable as AUM

Impressive

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 !
