Hi Barney, thank' s for your answer, to be honest i think that the only key or at least the most important  to Pog organ sound is that it has to be a  polyphonic octaver or harmonizer like the Hog  and the pichfactor algorithm seems to be monophonic mostly, the slow attack can help the job but the main thing is the polyphony, i agree with you that the Pitchfactor has many wonderful algorithms that's why it' s hard for me to decide to swap the pog for the pitchfactor, the eventide from the demo is just wonderful but not so for the organ thing,  and i just can't have both.
