I appreciate all the feedback - there's a lot of modules that I'll read up on, the drum machine will evolve more before it's final state, that's for sure (if there even is such as thing as "complete" with eurorack systems =P )
There's a lot of modulation in the second iteration for sure, and I wouldn't end up with such a beast in the real world, as I would buy it piece by piece over a long time, and would find the soft spot long before something like this. That said, I could probably skip half of the mirrored modules and still have enough. And I do enjoy the use of 1U-modules that was suggested earlier, so I did another iteration, this time with 7u + 104hp:
I swapped the Performance Mixer mk2 with mk1, as it is much smaller, and should be enough for this set of modules. I like this setup, but just so it's explicitly said: I probably won't end up with this. I plan to buy modules one by one over a long time, and interests will change with experience and research, so who knows where I'll end up. That's part of the fun with modular synth for me ^_^
I might throw out Metron altogether, as it is quite big for such a case, and rely on the Oxi One as sequencer for drums. With the freed up space I could add back Pam's, which could handle the work of handling accents (thanks for the advice, hadn't thought of that), hell, I might even add back Scrooge (I'm fond of the idea of the other drum modules handling "traditional" electro drum sounds, and the Scrooge just adding chaos and cool details) and their new extension, Della, and use Scrooge as the off-load sequencer. But I just saw Cinematic Laboratory's video on it, so I need to understand it better first (hopefully it will be added to MG soon).
All to say - who knows where I'll end up wrt the drum machine. The exploration is part of the fun, and thanks again for the feedback, it gives me even more ideas ^_^
