Also since you are brand new to modular, you might want to instead get a basic oscillator VCO module and VCF filter module. That gives you more control and a better understanding of how oscillators and filters work.

Not to mention, if you get an identical VCO to the first, you then have the ability to slightly detune one against the other, which results in a much beefier sound. The Odessa is sort of an exception to this, though, in that you can work directly with the harmonic spectra and dial in exactly the timbre you want right there. But Plaits, regular VCOs, and the like definitely benefit from detuning.
