I think the a used mpc 2000xl,or if you can find a 3000 cheap get the 3000..I dont use no vst or computer programs for beats,but I would say that you have a midi controller,you can then use the mpc to sequence the drum sounds and samples on the mpc,and sequence the vsts on the computer,You will need a mixer,at the very least a cheap 2 channel dj mixer to monitor the sounds.
