ASM Leviasynth Keyboard is a powerful 16-voice hybrid algorithmic synthesizer, representing the next step in the evolution of instruments from Ashun Sound Machines. The unit offers a unique architecture based on 8 oscillators per voice, each capable of utilizing over 300 waveforms and 7 independent oscillator modes (including FM, Sync, and Phase Distortion). By combining digital precision with both analog and digital filters, the Leviasynth allows for the creation of incredibly complex sonic textures that go far beyond traditional FM synthesis.
The instrument is designed for maximum expression, featuring a 61-key Polytouch keybed with polyphonic aftertouch and a four-octave ribbon controller. A significant new feature is the large 4.3-inch color touchscreen, which, combined with ASM's signature button and encoder workflow, provides lightning-fast access to deep parameter editing. The Leviasynth also includes a built-in 3-track sequencer (notes and macro automation) and an advanced arpeggiator with probability functions, making it a complete tool for both live performance and sound design.
