Chromagnon is designed to meet your needs (you have a Vidiot, but would prefer a core synth in eurorack format). Once you have Chromagnon, you can go in any direction your work demands. Sensory Translator, Staircase, Pendulum, Bridge, Arch…there are a number of good Expedition series complements. Chromagnon + Fortress, Memory Palace, Escher Sketch, or Diver would also work beautifully. You will know better what you need next after spending some time with Chromagnon.
Another direction would be to go with an all-Orion setup. TBC2 + Diver + Memory Palace + Escher Sketch & Fortress makes a very powerful video synthesizer capable of complex pattern creation or elaborate processing of external sources. Add Vidiot to that mix and you’ll have a deep well of possibilities.
