Fwiw, I personally am not a big fan of the PM resonator by itself.
However, mixed against the VCF, it's out of phase and creates some really nice cancellation type filter responses.
So while the resonator itself isn't voltage controlled and limited as a stand-alone box (for my purposes anyways), using it against a standard LPF can create some really nice Oberheimy notch type sounds.
By itself, it can help in the synthesis of resonant body instruments and special effects (adding big-time bass or sizzling high freqs), but when used in conjunction with an active voltage controlled filter, it can do a lot more in my opinion.
As noted, Wakeman made many suggestions to Moog which were incorporated in later PM's. I once owned a new PM and it was a "post Wakeman" version.
I've since worked on several earlier versions and appreciate the changes that were made. Definite improvements in many places.
Even a bit easier to service.
I've stopped working on PM's completely now though.
Too heavy for me to lift with back problems.
But I have lots of spare parts left over including several NOS boards that contain the resonator section, VCF, etc.
I even have a Polymoog Keyboard model in a flight case here that I don't know if the owner wants back. It's in need of help, but I'm not going to be the one working on it.
It's the 14 preset model, not the model with the resonator section.
So I'll ask the owner if I should give it back, sell it or whatever.
It would be nice to get it out of here one way or another.
Perhaps another coffee table to be?
