Hello!
Cool project.
It would help to have a bit more context.
What type of music do you intend to make?
What level of control do you envision (randomness vs programmed sequences vs playability etc.)?
What type of drums sounds do you prefer ? (analog vs digital)
How much HP?

Here's a stab at a 4 part skiff I would like to build

I'd clock with a Pique, it has two tracks (so the second one can be used as LFO for modulation). Then sequence with a Steppy (plenty of options, randomness, playability, memory slots).

Then I would have 4 Noise Eng Legio modules...they released a ton of firmwares (Kick, percs etc.). They give you a good range of sounds, some modulation cv inputs etc. - and you can repurpose them as oscillators, filters etc. in the future (I use the Tymp Legio for kicks, and like it -it can mix and duck an input)

I would then get them all through a module with fx send/return like mega tang and add an effect...clocked delay for ex. like FX Aid.

Some Legio modules can mix an input, so one can chain them, eliminating the need to add a mixer.

Again, really depends on context, objectives, and budget. One good module with modulation can also be great drum kit of course.

Let me know your thoughts :)
