Robotic Drums

By Big Robot Studios

This app is only available on the App Store for iOS devices.


Drum synth with probability sequencer. Demo video here:

Robotic Drums is an analog modeled drum synth coupled with a probability sequencer. This special combination, makes the app suitable for live sound manipulation, sequence experimentation and regular beats. The main highlights for this app are:

- A minimalist interface, with a high emphasis in flow.
- 8 analog modeled synthesized voices.
- A probability sequencer. You control how "random" a sequence is.
- Quantized pattern switching.
- Dropbox support for saving sessions and sharing across devices.
- Audiobus support.
- Midi out messages when voices trigger
- Midi in - Change patterns via note midi messages
- Midi clock sync support.

Some details:


There are 8 analog modeled synthesized voices, each with a noise and an oscillator section. This flexible configuration allows each voice to generate sounds that range from punchy bass drums, to snappy snares, to lo-fi tones, to sound effects and much else in between.


The sequencer for each voice is based on probabilities. A step on a sequence is not just a "switch" but a measure of "how likely is this step to be triggered". This allows for highly dynamic sequences that maintain a certain base, but never sound the same from one pass to another.


Each session can hold 16 patterns. Switching patterns in a live situation is always controlled by a "pattern quantization" parameter, which determines when the pattern switch actually happens. This allows for pattern switches to occur exactly when expected, maintaining the musical flow of a piece.


Sessions can be saved to Dropbox, this allows to share sessions across devices or even to use as an easy method to share patches with the community.

Customer Reviews

come for the drum synth, stay for the stochastic sequencer!

the drum synth is really outstanding in itself, very streamlined and easy to use, and great "retro" robotic drum sounds. the sequencer is a super stochastic pattern sequencer that you can use with virtual midi to add "human" randomization to other drum apps and even synths! The combination makes an app that is a must for any iOS musician's arsenal...
