Octachron is a flexible 8 Track MIDI Sequencer with rich modulation and sequencing capabilities. It is optimized for drums but also fun for experimental melody lines. It works standalone or as AUv3 AudioUnit in your favourite iPad DAW (like AUM, Cubasis, Beatmaker, ApeMatrix or Nanostudio etc.).


“An exciting MIDI sequencer with advanced features” (Synth Anatomy)

“Particularly the probability parameters are a lot of fun” (Amazona)

“Octachron controls just everything with iPad” (Gearnews)


*Please notice: Octachron is a MIDI sequencer and does not create any sound of its own*

We believe in specialization, so Octachron is focused on in depth MIDI sequencing. Control your favourite iPad drums like Ruismaker or MV08, synths like Zeeon or Model D or any hard- or software MIDI instrument with it.


*iOS 11 or higher required. If used with a host software, this has to be compatible with the MIDI AudioUnit standard.*
