I tried recreating some of my patches on Synapse Legend and it can sound surprisingly close, even the filter feedback works in a similar manner, but the resonance sounds better on the Trigon, and it seems to have better stereo separation when using the voice spread.
Tried that 12db filter feedback, with high resonance patch I posted earlier.
It shows that Synapse did some good modelling, and the Trigon-6 is pretty much a polyphonic Minimoog
I don't know if I will keep this Trigon-6, the limited modulation and features to price ratio is always on my mind.
And some other synths beckon me.
