Semantic Daniélou’ comes with a bank of 46 sounds, chosen for their harmonic qualities and diversity. In addition to the full scale of 53 notes per octave, the instrument offers 180 different tunings, themselves bringing together numerous scales. With these tunings, the novice will immediately obtain ‘musical’ results, while the expert in microtonalities will be delighted to exploit tunings with larger numbers of notes such as the 12, 36, 45 or 48 interval versions of the Daniélou scale. Not to mention the ability to trigger a ‘drone’, or refine sounds by adjusting their attack, decay, adding reverb and delay, and so on.
