An otherwise simple 2 oscillator synth, but with lots of assignable modulation sources. Lots of hover help messages.
Great choice for dubstep or electro house genres. You can add plenty of grit with the phase distortion and waveshaper, and then modulate those with an LFO or ADSR. It's one of the few synths that can approximate the sounds of Massive without using wavetable synthesis. Lots of filter models.
It's free so do yourself a favor and play around with this synth, or at least check out the presets to see what this bad boy is capable of. It's not capable of everything, but it certainly has a unique sound a personality to it.
