Thanks Paul for your explanation. In a first time it's for sound and space purpose, but as I start producing sound on my computer I look for a drum that i can plug on the computer.
But instead of a midi controller I would prefer a simple 8 track mixing table because I already have a good sound system.
About the budget, it's not my primary concern but Idon't need to have the greatest drum.
I have a look on something like Roland V-Drum, or Yamaha TD12 with "real pad".
There is something I need to focus on if I want to buy a secondhand drum ?
