I have already tried the .wav to multipad feature on the PSRS-750 and it works perfectly. I assigned all 4 multipads to 4 .wav songs I have on a usb drive. Once selected I saved this multipad bank in the user area. When I call up another style and with the one touch link light on, the multipads changed. When I then select my user bank it took about 3 seconds for the 4 full length .wav songs to light up and be usable.

To answer the question regarding how good the audio styles are you need to know that unlike the ketron audya styles where all the ones I heard sounded like they were all done in the same studio with the same microphones, the Yamaha was totally different in my opinion. Yamaha choose different mics, different rooms, different ambiance for each audio style. As I mentioned earlier, the pop and rock 60's audio drums sound just like you would have heard on a record recorded back in 1960. The quality of mics, effects, etc. were very different than we had say in the 90's. The drum set used in the Rhythm and blues styles sound very "live" and more contemporary in Yamaha's choice of mics, etc. In the dance styles the drums are a mix of electronic and live and sound very contemporary. The 2 audio styles in the Jazz and Swing styles also show a very live and real brush and cymbal audio loop. To some it up, I think you will find the Yamaha audio styles to be very different from the Audya files. This is not to say one is better but you will have to experience this yourself. My first impression when only hearing the 2 in the pop and rock catagory was mixed. I didn't really understand if the ambiance I was hearing was what I was expecting. I quickly realized that this audio style's drum track was exactly the type of drum track you would have heard in those two 60's tracks. It wasn't until I listened to the Latin styles, the Jazz styles, the R&B styles that I understood what was being presented to me the player. Soon enough you will all get to hear these styles at stores near you I hope and then I will enjoy reading your experience with the 950. Customers in my store today loved it! And all those superarticulation guitars from the tyros4 are really amazing!
