Now with Arpeggiator Mode and iPhone/Universal support!

SENODE is an innovative music app based on the idea of finite state machines. It works like a polyphonic modular step sequencer with probabilistic steps. This app is perfect for generative music and complex sequencing setups. Senode syncronizes its clock to Ableton Link or integrates as AUv3 plugin. All actions are MIDI bindable, so the steps can be triggered in real time from drum pads, sensors or other apps – a real live-performance instrument!

"Senode is something quite different when it comes to sequencing" - Create Digital Music

"I highly recommend Senode to everyone who is interested in generative music. It's such a fun app to work with!" - haQ attaQ

"A Killer App!" - A4iRebirth


The core of Senode is a graph of nodes connected by edges. You decide if Senode acts like a simple vending machine or a complex pinball game. Each node triggers a sound when activated, while edges determine the direction of travel. Instruments are controlled by emitters which send their tokens onto the graph and generate MIDI signals. That means, you can compose a generative music piece for a whole orchestra using the graph notation and a couple of emitters! It gets more interesting if you add random directions or emit multiple tokens at different time positions.


Compose and perform your music live using the intuitive multi-touch interface. Create, drag and connect nodes with multiple fingers. The on-screen keyboard helps you to visualize and edit notes easily.


The standalone app contains a simple but powerful subtractive synthesizer with main OSC (sine, saw, square, noise), sub OSC (sine), 1-pole lowpass filter, stereo reverb and ADSR envelope. Try the demo patches to get inspired!


Use the step record function to create new nodes on the fly, from single notes or using the chord detection. Use a drum kit, wearable sensors or any other MIDI device to control the steps of Senode. Enjoy the unique experience of being your own clock!


Senode is the perfect sequencer for all MIDI-capable apps. Play in sync with other apps using Ableton Link. Integrate with your favourite DAW using the AUv3 plugin (in-app purchase required). If you connect a MIDI interface, you can even control your hardware synths with the app.


Senode is made for live music performance. There are no default "beats" or "bars" and all actions are performed in real time. Tokens can be quantized to a clock (16th resolution) and support catch-up, which means you can hit all functions like a drummer "on the spot" and stay in sync, even if you're too early or a little late. By the way, the really cool stuff will happen if you break free from 4/4 bar schemes, start your sequences on off-beat timings or create crazy polyrhythmic cycles...

Too simple to use to be this powerful. Bravo! Wish list in order: 1. Node edges to multiple nodes needs an “and/parallel/always” in addition to the random “or”. This would enable true polyphony for linear sets of manually triggered nodes. E.g branch a series of nodes to sustain a note or chord through multiple ticks while the other branch triggers on every tick. 2. Ability to clone emitters and nodes or set default properties for each. This would be a great convenience. 3. Trigger emitters directly from nodes. With both “and” and “or” options could accomplish #1 above and more.

Ok what in the world THANK YOU! Ive been looking for something like this forever. I am running the app on my m1 macbook pro and then outputting the midi to ableton. Seriously thank you!!! I only had it for 10 minutes… i wish the tempo could go slower but i guess i can work around that!!! I look fed to exploring any other works or developments thank you sincerely!!

Really impressive!

This is a gem, highly versatile, well-designed, much deeper than you might think at first. Some small room for growth of features, but really very robust as is. Nothing quite like it on iPad ("Nodal" on computer is very similar).
