Very nice device from Roland!!!!
I am using the Roland SPD - SX for 3 years and I can say that is an amazing device from Roland .
You can do almost everything with this amazing electronic drums .
I tested it playing all kind of music : latino , jazz , rock , heavy metal , etc . . . and I can say that I did not have any problem . All the pads work PERFECTLY , and also all the LEDS ( above every pad ) .
Also the data communication with the external pads works perfectly . . . I use an electronic Drum Bass ( kick ) , an electronic Snare ( with double trigger ) and an electronic cymbal for hi - hat . . . All the products are Roland brand .
I just can say that I had a Small " problem " with this great machine , the OUTPUT volume is NOT so high . . . I wrote an e - mail to Roland and they told me that probably my cables are damaged . . . Anyway , this problem is very easy to fix giving more Gain from the mixer .
You must try it ! 100 % Recomended !
