Some notes to help you critisize the module flow choice more specific:
- My sequencer is the Arturia Keystep Pro, which has four tracks of CV/Gate/Velo, one of which can be a 8 part drum track as well. I'm leaning towards getting an Arturia Beatstep Pro as well, as I like the workflow and it is way cheaper than having a "basic" (linear 16 step type) drum sequencer in my rack.
- Outside the rack I have a Modal Argon8 Wavetable Synthesizer, Arturia Microfreak and Alesis NanoPiano as other sound sources. As my rack grows I'm considering selling at least one, I'm not sure which one yet.
- Mixer is a 1010Music Bluebox (non-eurorack version), so mixing is mainly done outside the rack. The mixers in my rack are used to create some sub-mixes for drums or bass sounds to have some free channels on the Bluebox for my other synths.
- The Addac 213's are meant to prevent very long cables running from one rack to the other.
- I make music in the styles of melodic to hard techno, house, deep house, breakbeat and sometimes drum 'n bass.
