I have no experience with midi (other than what I've read online) and I don't yet have any midi equipment to play with (but I have several devices working their way through the mail system).
Is it possible to have multiple midi keyboard controllers set to the same midi channel, but transposed to different octaves, controlling the same sound generator? Perhaps a better way to ask that is what problems am I likely to encounter having multiple keyboard controllers daisy-chained together that are set to the same channel?
I'm getting a Memotron M2D sound generator - it only listens on one channel, but it has three voices that can be split across different key ranges of the 128 midi notes (C0 to C10 or whichever numbering you prefer). Eventually, I plan to midify an old organ pedal board and combine this with two (small) midi keyboard controllers so that I have a different voice for each manual. From all my reading, it seems like I should be able to set all these to the same channel, daisy chain them into the M2D and as long as I have the octave ranges set so they don't overlap and match the mapping in the M2D this should work. However, I can't find any discussion of merging multiple controllers into a single device (lots of discussions of chaining multiple controllers to multiple devices or one controller to multiple devices). From what I've read, the biggest potential problem seems to be that a controller may not merge the data it's receiving on the "in" port with the data it's sending out - i.e., it may simply drop all the incoming midi data and only send out it's own data. However, for dumb controllers (i.e., that have no sound generating ability, like the Arturia Keylab) I can't imagine why the data coming into the "in" port wouldn't be passed along to the "out" port, so something like the example below should work (in my mind).
keyboard 1 (chan 1) -> Arturia keyboard 2 (chan 1) -> M2D (listening on chan 1)
But, I have zero experience with midi at this point.
