Hi there -

Here is what I got for now:
ModularGrid Rack
PNW will supply gates and LFO's.
Chord V2 will be droning and will be modulated by PNW.
Disting MK4 will be used as effect-unit for now.
HPO will output to my headphones while patching.
Case is a Rackbrute 6U.

I actually think this looks like a great starting point if this is your first foray into Eurorack. What makes this work is that you've got a clear vision ("an ambient droning rack for chords"). This setup wouldn't work for everything, but I think it's perfect as a starting point.

Pamela's New Workout is a tremendously flexible & powerful source of clocks and clocked modulation, and its ability to internally attenuate the level of modulation coming out of it is super helpful in a compact system like you're describing.

I haven't used Chord v2, but the fact that you can get both chords or single voice(s) out of it makes it a good starting point. I might consider swapping it for Plaits myself, but they're both great.

Disting should be a nice utility player - can be effects, as you note, or lots of other things (a quantizer if you wanted to use random voltages out of PNW as a sequence, for example).

Good luck with this!
