I recently updated to 10.6.8, and found that MIDI notes started to "stick" or "hang" when recording MIDI in Logic 9.1.4 64bit. I would play a staccato line, and then look at the MIDI in the piano roll editor and find a few notes lasting for several bars. I went back to 10.6.7, and the problem is no longer a problem. Has anybody else had a similar issue? And if so, is there an explanation or a fix? Makes me worry that there may be problems afoot down the line with the new OS Lion â€“ although, as PPC apps (which includes many installers, but not necessarily the products they install), and rosetta-dependent apps will no work under Lion.
