Acerca del Helix, mi apoyo. Su interfaz, principalmente la de sus envolventes es

Helix beta by Audjoo
The last free beta version of Helix before the final commercial version has surprising specifications:
It is an hybrid synth that combines substractive synthesis and wave shaping, with 4 oscillators,
16 voices unison per oscillator with a total of 64 oscillators per voice, spectral morphing, 3 lfo's, 3 envelopes,
2 step sequencers, modulation matrix plus and effects like stereo reverb and delay...
It sounds good, 80's, fat, techno, dance... Not easy to use, but powerful.
