Some Logic Problems Can Anyone Help ?, EXTERNAL H.DRIVES - KEYBOARD - CORRUPT AUDIO FILES...STILL !! Options

[PAUL R]

I have got a few annoying probs with Logic - I,ve been using it a year and getting on reasonably well - infact finished my first album on Logic !
RUNNING 2.5 G5 Dual with 3 gig ram / Logic 7.2 / MOTU 24 io supports all resoloutions.

Firstly I still get the audio corrupt messages after a year when opening a song damaged audio file message comes up...Also whist actually tracking,occasionally the new audio recording will just play back as white noise !!
I'm set up for 24 bit recording and tried all other different settings,resoloutions and audio formats,still this happens quite randomly..I then have to close and re-open the song THEN Logic 7.2 allows me to repair the audio file - Its not a major problem but HAS ANYONE GOT ANY IDEAS ??? Logic support never could figure it out.....

Secondly - my keyboard ( not contoller the typing one ) will stop working - again randomly - I can't stop or start logic and Zoom etc stops working...again I close it down and it is fine for a while..just an annoyance..ANYONE HELP ?

The latest annoyance is with plug-in samplers - I bought BFD drum unit and more recently EWQL symphonic orchestra.
Knowing how these take processor and hard drive space I bought 3 Lacie extreme drives one for drums one for audio and one for orchestra - I got a pci card for hi speed firewire and off I went.
The BFD won't work in 24 bit mode ( my project is set to record 24 bit - but should'nt affect the drum sampler )
it chokes,stutters and generally is a pain...it will however work in 16 bit mode - that gives less detail and footprint on my system...ok I can get by thats fine..
THEN recently ( a month or so after BFD ) I added ni kompact Strings plug in/library from Eastwest Symphonic and...guess what? Same problem as BFD !! Chokes,white noise..its horrible..but with EWQLO you can't change the sample resoloution - Although I got the Direct From Disk stream running etc.
Yep - I tried support and updates on these units.
Yep - I installed latest updates.
Yep - I contacted support and related forums.
Yep - No change - still chokes and garbage noise in both units...
I have moved the samplers and libraries to different hard drives including the internal one and still no change...
It is my guess that the external hard drives can't 'KEEP UP' with the processing
To be honest - I really don't know..thats why I'm here.

I just wanna make music not spend all my time in forums and support lines.

Logic as a programme is excellent - I'm not tempted to but my old 16 track back ( anyway it went to Jamaica - some reggae band bought it ) but it seems that some external hard drives and 3rd party plug -ins don't interact correctly with Logic !

They say that their products work seamlessly but I wish these manufacturers would own up and tell you that your gonna have problems before you have parted with all the cash and done troubleshooting for them !! They NEVER offer your money back - which in any other product service would be illegal - if it don't work - then money back I say.

Sorry
Thats my rant over with...

BACK TO THE POINT OF THIS

Can any one offer realistic comments and possible soloutions to my hard drive / sampler debarcle - Is there a way of testing the speed of the Lacie / pci firewire units ??
Maybe I expect too much from My G5 Logic set-up..
By the way the samplers were all running inside an otherwise empty song - so what chance would I have of running BFD 24 bit and a string section inside a tune with guitars and vocals ???
Less than NONE says my cynical side.

ha ha.
Thanks for reading

Outside some issues inside Logic/plug-ins…

Makes me think about some hardware issue:
Are you running your setup from a power conditionner or not?
Have you tested your RAM thoroughly? (use memtest in Single User Mode)
Have a look at it using my tip in Open Firmware as explained here in the post of "Sun 18 Jun 2006, 20:40"
Is your Lithium battery ok (should be tested 3.6 V in place +/- 0.4V)
What's plugged on your Mac in firewire and USB?

Some tips are on the hairy side, if you want detailled procedure, I'll explain. (I know, I'm a geek…)

I second the memory thing.

Software is unlikely to be causing file corruption like that.

any time you get white noise like that it's probably because some key bits of the audio format has been lost or jumbled around and the little ones and zeros are no longer lined up as they should be , basically resulting in junk. In audio, junk = white noise

Scan ALL you hard drives for bad blocks too.

It's also possible that the CPU is faulty in some way and is failing math every so often. If 1+1=1.009673862 the rest of that process will be junk.

try and rule out the MOTU as a problem too, run BFD in 24 bit with just built-in audio for example.
