Hi Sokratis thanks for the info. let me ask you a question. I understand that all the three methods you mentioned allow me to use my audio drums and audio guitar, right? But how come is doesn't generate a problem of synchronization with the midi parts of the style I want to create? The audio guitars or drums might play rubato and so you meed to somehow let the midi know how to accommodate itself to the rubato style of the audio, don't you?
