I do agree that there is a problem with the way the outs work on the Sd1. Right now I have assigned Drum2 to out 3 so that it gives me a quick control of the drum2 volume through my mixer, since Sd1 doesn't offer slider volume control and the button volume controls are very awkward and slow for me. Nothing beats real time slider volume controls. Just because I assigning Drum2 to out3 this makes the Drum1 which is still assigned to L&R totally dry. This is a serious problem with the Sd1. Sd1 is supposed to be more of a live performance
keyboard than a studio keyboard. for people who are using it in the studio this is not a very big issue. Also they really have to add loop recording in pattern edit and also in the sequencer. Even a very cheap yamaha does loop recording.
