Thanks Robh. So I see where my understanding is severely lacking.
Here is my analysis ... the Roland has banks, and they are either GM banks (presumably default) or some other bank (which my manual shows me how to select)
So for starters, I'm keeping the Roland in default (this is GM I presume, I only need two channels for start -- bass = 2 and drums = 10)
RB comes up with GM by default, and the GM button above the keyboard lets me change patches. Under the Track/Drum/Patchmap I have a note that there is none ... this is empty.
There are no drum patches ... this actually has been my problem all along, as I can't assign any drums to Channel 10 (well, vibes or wood blocks, but not real drums). The Roland has default drum kits on Channel 10, but there seems to be no way to get to these.
On the Roland, the drums on MIDI channel 10 come out as piano (the default for most of the channels)
I presume 'Omni' means that channel X on the sequencer controls Channel X patch on the Roland?? The Roland manual doesn't make any references to 'omni' ... is it possible this is called something else?
Do you see anything obvious that I am doing wrong? I wanted to use the RD700 patch (of a .DK file) because that is how I thought I could get a set of drums.
