Verified! This was driving me nuts but there's indeed a bug where you need to add 1 to MSB and LSB values for banke select.
In Ableton, "Bank" is MSB and "Sub-Bank" is LSB. You need to add 1 to desired index. For example, if you want to specify MSB a value of "0", you have to specify "1". Likewise if you want to specify LSB a value of "32", you have to specify "33".
Program change interestingly enough is 0 indexed, so you don't have to add a "1" to it.
This is what I needed to do get bank select working on my Motif however I suspect that's the case in general, unless my Motif is off by one in which case I'm not going to figure that one out.
