I've come back to this thread a few times over the last couple months, and the release of the RK-008 and Cuckoo's video on it [link-to-youtube] made me think of this situation again.
I did not know about song mode learn/unlearn, that's excellent and mostly what I'm looking for as well. The RK-008 seems to do exactly what the OP was asking, and what I had hoped for as well but maybe this is as close as we get. Setting my controller to channel 16 and learn/unlearn in Song view is a workflow that I think I can get used to.
However I do have a question though about this type of setup;
This seems to only work if I have the controller sending to the Deluge only, or using a channel like 16 that the synth is not on. If the controller is going to both the Deluge and the synth on the same channel, it's sending double notes. I can't seem to figure out how to turn off midi through on the Deluge without muting the track in Arranger view. I could've sworn the Pyramid did this by not passing through incoming midi but maybe I'm misremembering. Going into the settings on the Deluge and turning off midi through doesn't seem to change anything. My hope was that I could just learn each track on the Deluge to each channel, save that as a template, and then only have to switch channels on the controller. Or would that not work anyway because the Deluge only records one track of midi at a time?
