The sound range is five octaves and the instrument consists of 4 sections — piano, that synthesizes piano like lead soundings of different timbres, analog string machine, that plays wonderful string sounds with soft attack and with the possibility to control release, tremolo and the pereodically repeated beat-fading sounds.
