After manually entering midi files for a couple of songs I am looking for a more efficient solution to create midi files. So I look for a drum pad without sound engines but with an easily programmable midi output (reprogrammable as I change drumset in BB). As I will enter data via Ableton a USB midi IF is ok. Looking for something in between the small 3 x 3 pads on keyboards and an e-drum. Anybody who has some good experience to share?
