So I'm looking into either getting Akai's MPC 500 or 1000 but I'm trying to decide on which one. I'm trying to budget myself but I'm having a hard time choosing. I've looked on Akai's website and other sties for specs and details but it doesn't seem like there's much difference besides 12 pads vs 16 pads. Does anyone have experience trying out both of them? Are there any other major or minor difference between them?
