Thanks Hawkeye! I'll try going to a store if I find the time, but I think I'll just order online, always such a hassle going to real stores ;)
Thanks for the tips rosch. I'm not planning to build a Midibox64 though ;) I'd really like to have some knobs on the keyboard, as well as Sequencer Rec/Play buttons. I think that would make for a really nice workflow, being able to record sequences with CCs into my MPC without ever taking my hands off the keyboard.
Thanks nebula. Do you have some more details maybe? Do you use one, or have you used one?
Thanks jojjelito. The K5000 sure looks nice! I'll keep it in mind. It's a little bit over my budget though...
