Vortex Sound Research

Hello synth lovers

I'm new to the modular world, that's why I'm asking you for help. I was struck by the ability of my volca bass to be able to sequence three different tracks, one for each oscillator. These VCO can also work in a single sequence of course (with sick detuning). I would like to develope a modular that has this characteristic of the volca bass but the versatility of a VCS3 (two VCA and two VCF and a spring reverb). To make everything work it would take a good sequencer with more steps than those of the volca. Can anyone help me in this venture? I don't even know which case I could use, and how much it could cost.
