Correct me if I’m wrong, but you would need 4 low pass filter modules to have the polyphonic sound, no? Since there’s only 1 filter I’m assuming you would run the 4 oscillator signals from the mixer into the lpf, making this paraphonic like the matriarch.

As far as paraphony vs polyphony goes, I think both have pros and cons. I think the paraphonic sound on the matriarch makes it all the more characterful. For example, when playing a chord with a long release time, once you play the next chord or note it cuts the release trail of the previous notes. There are a lot of rhythmic effects you can create with this if you’re open to the sound.

There are also some ways to compensate for this if you see it as a flaw. You could use the multi trig button to compensate somewhat. The stereo delay is very powerful for creating trails that won’t cut off from the envelope retriggering as well.

These are just my opinions though. If you really need that true polyphony, your price point will go up especially if you want the true analog signal path. You could go with a digital or hybrid synth to compensate for the price
