I think that's quite true in this case. I started typing, thinking of how I was worried about this exact situation with my design, and I was thinking that maybe this extra layer of flexibility might be a hindrance for the mbseq which is well loved for being quick to edit... But then I thought... How often do we connect a synth that we haven't used before? I mean... You can spend a short time to make a few instrument maps for your gear, and maybe a couple of 'spares' for when your mates come around to jam... Then you won't have to do it again after that... I guess it could be a short initial investment of time, to save lots of time later? (and you could use a text editor to do quick block copies and search/replace... Maybe even simple scripting could be used... oh, and there are lots of softsynths around that export .ins files these days...) Edit: and the copy function would make it even easier :)
