you might try to find a YAMAHA RX-5 , it was their flag ship drum machine in 1987. But don't let the age fool you , all sounds are editable and it has 12 individual outputs and it is very easy to figure out because all the job fuctions are labled on the machine. It's like having the manual on it . It can have a mean sound and they usually go for around 200$ , it also has MIDI in, out, and thru . Not many drum machines have that even today.
