I hope this means we can have class compliant USB midi devices with Jitter correction and "interrupt driven" transfers (as opposed to the low priority bulk transfer mode used in USB midi 1.0). This should mean way better midi clock synchronization at the cost of a bit latency. Unsure how much work there is in for the DAWs, as they will have to not only use the new API's but also send midi events some millis early to take advantage of the jitter correction. Hopefully there is someway for the Alsa client to determine this automatically so we don't have to manually twiddle with negative track delay or similar "hacks"
