The styles can be edited,aranged,and use alot of FX,like chorus reverb and setera. I recoments to set the volume on the keyboard on zero.Īfteral you do not need anny sound created by the PSR-S550Īs the sounds wil be used in reason itself. The only drawback is when you play on the keyboard,the sended data thad recieve in reason program have an little delay. The S550 also work with most styles.However not all styles can be used.ĥ Octaves and full USB midi,Exelent usable for example with reason 4
