After studying the specs, and listening to the demos, this PRO3 will be my last synth, I will be ordering the SE edition because the tilting of the panel will be crucial to me since I want it placed above and beyond my Quantum.
The ladder filter sounds moogish enough to my liking, and the distinct OB filter is just such a lovely addition... All of the other small irritations I had with the REV2 seem to have been removed... LFO slew rate, the oscillators do have a per voice vca obviously, the sequencer is now useful, and not just a gimmick, more distortion and saturation options, mod matrix at audio rates and since there is no layering, the interface is much more hands on with one function per knob on almost all parameters.
It seems I will be on the Sequential wagon anyway...
