Description
The ASM Leviasynth Keyboard is a 16-voice hybrid algorithmic synthesizer with a 61-key Polytouch polyphonic aftertouch keybed and a 4-octave ribbon controller. It shares the same dual analog/digital synthesis engine as the Leviasynth Desktop, with 8 oscillators per voice, 144 algorithms, an analog 4-pole low-pass filter, and 18 digital filter types, in a full keyboard instrument form.
Synthesis Architecture
Each voice contains 8 oscillators with over 300 waveforms and 7 independent oscillator modes. The 144 preset algorithms determine how oscillators interact (phase modulation, FM, PWM, HTE sync, three phase distortion types), plus one customizable algorithm per patch and algorithm morph for continuously variable routing. An analog 4-pole (24 dB/oct) low-pass filter with pre-drive saturation and self-oscillation works alongside 18 digital multimode filter types.
