It's brilliant. I have played a true PPG, i have experienced also the infamous crashes and lock ups. This VST instrument, for me, is an exact reprodution of the real beast without the problems and with some nice adds, like the midi sync. The sound is great and it not possible to achieve bad results. Of course, like all complex and versatile instruments, we have to struggle a little to obtain certain simple sounds, like modern techno basses and mooglike leads (remeber Muon Tau, Quadrasid and the Rebirth Basslines).
But if we try, it is possible to "make it simple" also on our PPG: remember to avoid all the doublings and detunes.
Arpeggiator is very useful and nice, the interface is great. For the "no name" presets, is it difficult to listen them in a half an hour and to write something? I use PPGwave everytime for all, pads, basses, "sequencers", bells and i have also programmed and sampled some 808 type drums.
I would like to have a more versatile "stereo" mode and continous detuning, some "smooth morphing" for the wave shiftings and the choice to load my sampled waves (like PPGwaveterm or WaldorfWave) but perhaps these could lead too far from the original PPG.
