Modul is a web-based MIDI step sequencer. Modul plays well with MIDI capable devices. Think of it as a brain dedicated to control your synthesizers, drum machines and samplers all at once. Because Modul is web-based, it runs on any device with Chrome support. The current version of Modul is for desktop use primarily. You can use Modul on your smartphone or tablet using Chrome and native apps are coming soon for iOS and Android.


  • Web-based, runs in Chrome
  • Send MIDI note or CC values per step
  • Set MIDI channel per step and per track
  • Mute tracks
  • Adjust the number of steps per track (great for poly-rhythm)
  • Send MIDI clock
  • Load/Save session

    What's coming

    Here are some of the features we plan to include in future versions.

    • Native mobile apps for iOS and Android

    Important: you need a MIDI interface to use Modul. If you don't have a MIDI interface yet, take a look at the T4, a class compliant USB MIDI interface that will work with your smartphone, tablet and desktop computer as well.
