Took a crack at this myself, didn't fill the whole rig out but made some changes:

ModularGrid Rack

  1. I'm not sure you need a Samara and an MVP both, so I dropped the MVP.
  2. In my personal experience, I wouldn't say Rings is actually a great techno voice, so I swapped it for a Manis Iteritas.
  3. I'm not familiar with the Stereo Dipole, but it's a lot of HP. I swapped it with a Viol Ruina and a Ripples 2020 both of which work for techno in different ways, and give you different filter characters to play around with.
  4. I added an Intellijel Quad VCA as I'm not sure you'll always want to use an LPG, and you could use a submixer in here anyway.
  5. You need some effects imo so I added a Happy Nerding FX Aid XL, I have an FX Aid and it's a nice module with a ton of range.
  6. Put in a Disting Mk4 because in a rig this size you can always use a Disting to fill different holes.
  7. Add a Peaks clone, opening up a bunch more functions in a small-ish package, including the ability to run drums in the rack if you want to.

I don't make techno so this may not be exactly right, but take a look and see if some of these modules resonate a bit more with what you're aiming for here.
