808 kicks are pretty easy with silk machine, it’s hard not to get 808 style from it, 909 you can find recipes in this thread:
you probably can get some roland styles snares/claps/rimshots by playing with the machines, probably won’t be 100% match.
with the 909 hihats imo you would have to go for samples, maybe you can get close with the ride but the engines are really nothing like the roland 808/909, at least from my experience…
if you don’t want to use samples, and I’m not sure why, perhaps consider pairing the rytm with TR-6s which is relatively cheap (especially second hand), can be sequenced from the rytm and has all the ACB synthesis for the 606/707/808/909.
