What it does
Three channels, nine source types
Each oscillator channel holds one source and two of 16 insert module types. Sources include FM, ring modulation, sync granular, a sample engine, a granular engine and live audio input.
Envelopes with up to 68 breakpoints
Six modes cover release, sustain, loop, retrigger, control-driven and linked envelopes, all with tempo sync. An envelope LFO sets its depth and rate per breakpoint.
Draw a wave, then edit 512 harmonics
Draw a waveform by hand and refine it in a spectrum editor with 512 harmonics. Etherion morphs between the waves you make.
Effects on up to 8 output channels
The effect stage has granular, multicomb, resonator, pipe, echo and multitap effects. It outputs surround audio on up to 8 channels.
A sound map for 2,255 presets
The browser places presets on a 2D map with 7 tonal range sliders, favourites and audition. A morph tool blends the current sound with the presets you select.
16 macros, MPE and microtuning
Modulate with 3 LFOs, 16 macros with MIDI learn and 4 audio-driven modulators. Etherion responds to MPE and polyphonic aftertouch and reads .scl tuning files and MTS-ESP.
