We anticipate the following trajectory: [1] About 30% of the packetization in -03 is new or reworked: all of the MIDI Systems journaling is new, SDP format parameters for timestamp semantics and journal customization are new, etc. So, we're expecting feedback on -03 on the changes, with a -04 that fine-tunes the new features as a result. [2] After -04, three parallel streams: -- Recoding sfront's MWPP implementation to reflect the changes in the I-D in the past 6 months, to reality-test the I-D. -- Widening the circle of review and comment beyond the current mailing lists (AVT, linux-audio-developers, and saol-dev) to get comments from the broader MIDI community. -- Work begins on ancilliary informative I-D's to explain how to write senders and receivers for MWPP. ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------
