a midi file has only one drum kit, unless it is the recent gm2 which many machines cannot reproduce. There is a difference between a midi file and a standard midi file which will play on anything, and a world of difference to a technics file. If you want to make a standard midi follow the specification, it is more than pushing an easy record button. You will find it useless compared to the proprietary sounds and features in technics mode. It's single advantage is compatibility across different machines.. providing you conform to the correct specification.
