Matrixbrute can be seen as a response to the shortcomings of modular analog synthesis. You get soft patching in a visually decipherable page, with an attenuator built in to each connection, midi sync to the sequencer and lfo’s, midi control of the knobs, full recall of patches. I owned a big eurorack synth before the mattixbrute and get fed up with how slow it was to get good sounds, not being able to save sounds that took hours to make, having difficulty following the patch through a mess of cables. People make some fascinating stuff with their modulars, but I lost enthusiasm. All to say, I think it is smart to use the matrixbrute as the core of a modular setup, so you can skip building a typical analog synth patch, and just use the eurorack modules to add on to what the matrixbrute already has, and does in a much more user friendly way. You don’t need analog oscillators, lfo’s, filters, waveshaper, sequencer, analog delay. If I were adding to the matrixbrute, I would probably focus on unusual modules, since the basics are covered so nicely. Stuff like ring mod, bitcrusher, wavetable oscillators, granular synthesis, sampler toys, unusual effects. Maybe just a couple things, and it would still be manageable.
