Zeppelin Design Labs Altura MkII MIDI Theremin

Wave your hands over the Altura MkII Theremin MIDI Controller with new Arpeggiator and Step Sequencer, and release a myriad of MIDI possibilities


The new MkII version of the Zeppelin Design Labs Altura is a major upgrade and it was already pretty cool to start with. Disclaimer: I’m part of an organization related to Zeppelin Design Labs, but I still think most people would have a lot of fun with one of these.

Like most of Zeppelin Design Labs products, these are available in kit or fully assembled versions. If you enjoy tinkering with code, the Altura code was written in the Arduino 1.8 environment and is available open-source on their GitHub page, link is further down this page.

This MkII version adds these new features:

  • Save and recall up to 21 presets
  • Program any sequence (arpeggio) of up to 8 steps, including extended notes and rests
  • Wave your hand to instantly transpose the arpeggio up and down the scale, always playing within your selected key
  • Use Tap Time to set the tempo
  • Wave to jump to double time or half time

In addition to the arpeggiator, the Altura MkII is also:

THEREMIN – By waving your hands over the Altura MkII, you send MIDI data to your synthesizer to control pitch plus bend, modulation, velocity and volume. When paired with a synth that responds to portamento, such as the Macchiato Mini Synth by Zeppelin Design Labs, you can recreate an authentic Theremin sound that always plays in tune!

MIDI CONTROLLER – In X-Y mode, both sensors transmit any MIDI data to any two Control Change numbers for complete creative control: shape your sound with a wave of your hands.
