IMO yes and I love it. But this is very subjective. I bought it, because it has those many modulation options, which are normally not available on other synths. For me it’s more of a sound designers tool rather than a bread-and-butter machine.
Those three VCOs and the filter generate a great sound, if just used like a typical subtractive synth. I got very deep organic basses with lot of bottom end, as an example.
But the Syntrx shines, when we experiment with the matrix. 16 modulation sources vs 16 modulation destinations, all can be a mix of audio and CV signals, and we can patch modulations, which are not possible with standard synths and sometimes hard with modular gear.
And even the most complex patch can be stored (well the connections of the matrix of course, not the position of the knobs)
