Yes. I've tried to explain this in the longer message I've posted yersterday. To summarize: the only standard required here is the SF2 specification: http://connect.creativelabs.com/developer/SoundFont/Forms/AllItems.aspx Which says about the SoundFont bank and preset numbers that "if the value [...] is not a valid MIDI value of zero through 127, or 128 for wBank, the preset cannot be played but should be maintained." If you calculate MSB*128+LSB for any MSB>0, the resulting number is not a value from zero through 127, so it will not match any SF2 bank number for a melodic channel. In my opinion, if only the LSB control change is sent, it should also be interpreted as the SF2 bank number.
