This synth is pretty comprehensive, 3 very nice oscilators with some great waveforms + unison, basic fm, etc, standard filter with LP, HP, BP and 6/12/18/24 db slope options, noise osc, good mixer, 3 lfo, 2 env, per-item modulation, and a huge FX section.
The real highlight for me, though, is that every part can be turned on and off. This is particularly amazing in a modular host like energy XT (which i use). So what i do is start with an empty preset, then turn on elements as i need them. So if i want 2 oscilators, i turn them on. Then say i want to use an external filter, i could just leave it like that, with nothing else. or i could switch on the fx section and add some chorus and a short delay, before going out to the ext filter. each lfo could affect each osc differently.
So the big thing for me is the ability to switch on things as i need them, and that sets this synth apart from many others in my collection.
