Iām going to co-sign this a little. Or rather: trying to recreate a drum machine in Euro will fill a row with single-purpose modules and sequencers, and as @alanza points out, there is perhaps more fun to be had with simple, cheaper, single-purpose machines.
If you are interested in percussion, finding alternate routes to it is perhaps more viable - like, people like taking a BIA and filling it with modulation and triggers and this gives you a useful percussive tool, without being a bottomless pit of drum modules. Are you specifically interested in drums or percussive sounds and patterns? The latter is achievable in lots of ways. (Iāve actually, naughtily, just used the raw output of an envelope as a kind of kick drum. Probably unkind to large speakers, though). Or, you know, using something like your Pico Drums as a source of always having a kick or similar around, just for texture, makes sense.
I am often bewildered by people theorycrafting cases that end up being half-full of Mutant Drums modules.
