If you are familiar with the series of drum machine/samplers from AKAI, in particular the MPC2000XL then you know how much fun it can be to make sampled music!
When I discovered Renoise I couldn't believe it! almost a substitute for my MPC! but, the interface is a little wide and has its own learning curve, nothing impossible just different. I wanted to control Renoise like I do my MPC. Quick access from one small set of buttons and the ability to create more or less bars quickly, erase a track or tap tempo to a track
