Thanks Stickman! Finally got it sorted though, with very quick response from from Roland Tech Support. But there really needs to be a Step by Step guide somwhere, see below for the process. Only things different from your description for the SPD-20, is that the SPD-30 connects with USB (but still has Midi also). Once SPD-30 is connected to your computer and you have Sonar running, you need to go to Options > Midi Devices then select the SPD in the Inputs and Outputs. Once you have done this, insert Session Drummer as a Softsynth Track, then select the SPD for the Input for that track (Midi Omni is fine). Then load a drum kit into Session Drummer. When you Right-Click on a drum in Session Drummer you will see a number beside the drum description, which you will need to assign to the pads in the SPD-30. To do that, in the SDP-30 go to the Midi tab which will bring up a graphic of the pad layout, (Use Drum Pre-set 99 which is a basic kit). Each pad will already have some numbers in there, but you need to change them to the numbers you see when you Right-Click on the drums in Session Drummer. The User Guide for the Octapad will explain how to navigate the menus and assign parameters, it's pretty easy once you know how, of course. Cheers, M.
