now that i think about it, i recall what i realized was the MIDI spec's intent: you are supposed to be stateful when parsing 14 bit controls. you always know the most recent MSnibble, and so when the new LSnibble comes in, you just merge them. libmidi++ does this already. the problem remains that you can't provide "atomic" access to the controller state: if it changes so that both the high and low nibbles need to be transmitted, an application can end up seeing it in the intermediate, undefined state where the LSnibble has been updated, but not the MSnibble. hence the timeouts needed to be able to delay updating the LSnibble so that you can be sure no pending change to the MSnibble is coming. --p ------------------------------------------------------- This SF.NET email is sponsored by: eBay Great deals on office technology -- on eBay now!
