Sorry in advance if this question drags on. Just purchased a Roland sh4d and trying to use my s61 with the Roland through a midi out from s61 to midi in on Roland cable. Are there specific settings I need to change in my Logic Pro X midi preferences and my Roland system settings to make them work together? I also read somewhere that I need to power my s61 through power cable as opposed to through usb to make this work. Please help. Thanks in advance
