Logic Pro 9 What to do when Logic 9 crashes


1. Say "oh no, not again. Not after I've just done a whole day's work?!"
2. Realise that Logic 9 has not created backups of your song file today. Last backup was yesterday.
3. Realise that on crashing, logic has not saved a version of the song called "song.crashed" or similar, like it sometimes does.
4. Post a message to Logic User Group, in the hope that someone can tell me that there will be some recoverable file, somewhere on my hard drive from all the work I've done today...

What caused it to crash was "instantiating" a logic eq plugin on a track while logic was playing back. Cue the umbrella then logic disappears with a crash report, and the helpful question "do you want to restart logic?"

That is a serious philosophical question at this point.

Can anyone advise me on the answer to question 4?

Three suggestions:

Keep using the comm + s key command to save your work as you go along.

Please attach the crash log to a post here (please do NOT copy it into a message, it may not fit and makes the thread very difficult to read. There is no guarantee, but someone might see something indicating why the crash ocurred.
Mail Apple's logic feedback, and attach the crash log.

For you, the first suggestion is by far the most important. It is a fact of life that computer applications may and do crash, saving your work regularly as you go along is vital.

kind regards

A sage once came to me, as a young man in the beginning of something called "direct to disc" recording, what they said was to become to future of the craft I had learned from a young lad. He whispered some magic spell into my ear, that to this day has saved me from many, but not all, a dilemma:

Save, save, save... or you will PAY!

So I took this advice, and made a placard that had this wondrous saying upon it, put it up on the new video window into my magic machine, and to this day i have been lucky to have not lost more than an hour at worst of my hard creative work that will be gone forever if I forget.

So there it is....
