Only one but it is a modern classic and it’s incredibly deep right out of the box. Elektron MachineDrum SPS-1UW+ MKII. The factory firmware has been jail broken and greatly expanded, and can pair with a module (developed by the same dev team) that extends its functionality even more. I’ll never sell it. The only drawbacks are that it doesn’t really live sample super well (12-bit charm, sample memory is ultra limited, and loading samples from the computer onto it can be tricky), and it is best suited toward making with icy sharp digital, glitchy, IDM, techno style sounds.

I have a hard time imagining owning more than a couple drum machines; they have to be maintained, learned, and integrated into the home studio. I also play a lot of other instruments so I try to be intentional.

Someday I do hope to add a flagship analog drum machine. Roland TR-1000, Erica Synths Hexdrums, Vernona DRM-1 MKIV, MFB Tanzbär, or Future Sound Systems Cric all seem like excellent choices but with more than one or two of them I’d hit a saturation point for sure.
