Logic Platinum Midi Communication, Random loss of MIDI I/O Options

[smplfly]

I run Logic Platinum in OS X on a G4 800. My MIDI I/O is a MOTU MicroExpress.

I start Logic and both of my MIDI inputs work fine (a keyboard and a drum trigger). MIDI data is recorded as usual. But I'll pause for a while to program a patch or read a manual, and the next time I hit record no MIDI data is recorded. The MIDI input monitor shows that nothing is going in, but the data already there still plays my synths.

If I quit and restart Logic, all works again.

Any help would be appreciated...

I had this exact same problem earlier this week. My Midi I/O is an Emagic MT4. The Logic InfoWeb recommended trashing the Audio Midi Setup preferences (in Library/Preferences, called something like apple.audio.midi - check this before deleting!!) and logging out. Not that it made any difference. Quitting and restarting or occasionally restarting my entire Mac fixed it.

However, this is what Emagic support e-mailed me later:

I would like you to try using MIDI on a default logic song.

While in Logic hold down alt and at the same time go to your file menu and select new.

A default song should open.

Now play on you keyboard.

If you cannot see any Midi in on the transport bar you have a problem with preferences if you do have midi in you have a problem with one of yoyr existing songs.

BTW, all typos are theirs ;-)

As my set-up is working again without doing this, I haven't had to try it so I can't vouch for it either way.
