About

Hydrogen is both a drum sequencer for pattern-based programming and a drum synth. Its simple yet feature-rich design makes it a versatile companion, be it for quick practice at home, professional usage as fully-fledged drum machine in your studio, or drum looper on steriods for your live performance.

Features:

  • First-class MIDI support
  • Highly customizable
  • Stable and performant
  • Loads of drumkits to choose from
  • In-depth control of instrument, sample, and note properties
  • High quality time-stretching and pitch shifting
  • Automate it using MIDI or OSC API
