Switched On recently restored a Moog Model 10 synthesizer. Before we sent it out the door we wanted to get a little bit of documentation to share.
This system consists of a factory arrangement of modules for the System 10. Each module was produced from 1969-1971 in the Trumansburg, NY factory.
It is very clear and immediate upon hearing the timbral quality of this system that everything described about the original Moog sound and the legendary 904a low-pass filter is true: lush, fat, warm, silky, harmonically vibrant, pure, etc. etc. One especially nice module that is included in this system is the Fixed Filter Bank. You can consider this to operate like an EQ with resonance! By driving up isolated harmonic bands pre-lowpass filter it adds a very pleasant sounding distortion that is unlike anything. You can hear it demonstrated in the first patch in this video. If you happen to have a MU or 5U modular system you can find recreations of the Fixed Filter Bank from synthesizers.com and COTK.
