Behind the extremely simple interface hides a complex polyphonic, microtonal synthesizer with a broad and flexible sound palette that ranges from classical beautiful tones to complex atonal noise, and offers smooth and fast transitions between these extremes.

The innovative keyboard design invites new playing techniques and covers the full range of a grand piano with the possibility to tune each note with an accuracy of 125 steps per semitone. To achieve this range with such a simple keyboard we designed a unique system of pitch shifting using four additional sensors. Pressing different combinations of them will result in 16 variations of keyboard transposing, including up to 3 octaves up and down, fifth, fourth, third, tone etc. Not only do you get the full range of a grand piano in a very compact design, TERRA also offers an entirely new and different approach to playing melodies and chords.
