I'm not going to give specific advice, but advice if I suddenly acquired your system and the things I would check.

My first consideration would be able to stop, start, and reset both the Nerdseq and the Erica Drum sequencer together. If I start playing one sequencer from the beginning, I should be able to slave the other. This might be done through MIDI or CV through clock and reset. I would look through both for Clock-In, Clock-Out, Reset-In, Reset-Out features.

Yes i asked to Erica Synths team and I can slave the Erica Drum Sequencer to Nerdseq easily or also use Drum Sequencer as master clock.

My second consideration would be a mixing. I'd just go Full-Monty and get the beast that Befaco makes. The Techno-System comes with a lot of sub-mixers. But I'd like to be able to take everything to one main performance mixer. Depending on what modules you get for the Befaco mixing system, you might not need the Intellijel VCA.

I was thinking to buy another 6U rack and take the WMD Performance mixer, another Vermona Twin out and the Vermona TAI-4.
Do you think Befaco Hexmix and expander is better ? I know there is EQ on the Befaco but I have a preference for WMD Performance mixer for the moment..

Third, utilities. How are you doing on sample&hold, logic modules, slew limiters, etc.
Will learn more things about those things. For the moment I will begin without those utilities in this first rack..

Finally, modules like Plaits would be a great addition as they don't need a lot of support... just a gate and pitch CV. I'm assuming that the main focus is the Techno System and your other modules will support it. Add in a nice reverb and I think you're near golden.

For reverb I was thinking about Noise engineering Desmodus Versio, good choice ?
