you can always grab super cheap Alesis SR16 from ebay and slap it through some pedals/fx/MS20/eurorack/whatever...
the built in sequencer is so easy programming...
Personally have multiple from over the years & DM5...
got my first one in the early 90s from somewhere/someone/somehow(don't remember anymore)
someone stole my yamaha RX7 & Roland TR707...
not the greatest or the worst drum machine ever used...
yet considering got them for free & resurrected via jumper wire then not complaining...
you can always try to snag cheap Roland MC303 if get lucky yet IMO the SR16 is easier programming patterns/songs...
