| br>don't know the SD1, it would be nice if something like that was available with an option to upload your own samples, with 1-2 assignable cv inputs.
There are a few options, though. Delptronics has a tiny analogue drum module. Erica synth has a 3hp sample player. Also no need to stick to self-contained modules, with a selection of sound sources (an oscillator, noise) and a dual VCA/AD combo you are far more versatile.
Also worth looking at: the endorphines BLCK NOIR. It is not tiny and not that cheap, but imho more value for money than the SD1 and has some good effects and playability.
Otherwise, also look for non eurorack solution, i.e., that new volca drum or even an electribe2 sample can be synced to modular. br> br>
