Hi Could someone help me. Afte Upgrading my OS 10.4 to 10.4.11 and logic 7 to 7.1 through internet, whenever anything I record and bounce in 4800 Khz sampling, it gets distorted in the burned CD. But if I do it in 44.1, it does not get distorted. I tried many ways keeping sampling to 4800 in Logic, MAC(application > utilities > midi sampling) and in my RME fireface 800, but even then it gets distorted. But in 44.1 it works fine. Please help me to fix this problem. One of my project has to be done in 4800. Thanks in advance. Tulu

Try bouncing your song to 44.1 kHz in Logic. If you bounce to 48kHz, your song will be converted to 44.1 kHz anyway when you burn the CD. Are you burning from iTunes ? Maybe iTunes have a problem converting to 44.1 kHz ?

Hi there, not sure I quite followed the question.. but as far as I see it, you have a few options. Use Logic, iTunes or even quicktime to convert your files from one format to another. Before you do any of this though, just to eradicate one of the potential problems, have you verified permissions from Disk Utility for the main drive? You should really always do this before software updates.. especially O/S updates. The other thing you want to make sure you have done as well is update your quicktime. Quicktime is the engine behind a few audio and video packages so pays to make sure it's up to date and compatible. One other thing you might want to try is changing export file type. I had similar distortion problems when I was trying to get really low bit rate and sampling files exported for a skype project. Exporting in WAV gave me no end of grief, exporting as AIFF was fine... go figure!?

Hi According to your instruction I have checked Disk Utility for main drive and found 4 errors as follows: 1. Incorrect number of thread record. 2. Volume Bit Map needs minor repair. 3. Invalid Volume free block count. 4. The volume Macintosh needs to be repaired. Now please tell me what to do. I new in MAC and dont know much about it. I use Toast 6 titenium for burn CD. I dont use quicktime. Right now tried to burn in AIFF and had the same problem. Waiting for your response. Thanks

Hi Tulu, Using Disk Utility click the repair permissions button and let it do it's work. If it can't repair the issues it will tell you. The majority of the time it'll be fine! You might also want to try 'verify disk' and then repair disk if neccessary. Do you have a backup of your system pre-OS 10.4.11? If so it might be worth switching to that. I wonder also what mac you are using: G5, Intel based mac? If you're on an intel-mac Logic 7.1 is not Intel compatible (universal binary) so it's not fully supported. The first version of logic to be Univ. Binary is 7.2. It's a paid upgrade, so might be tricky finding it now that Logic 8 is out. Best Rounik

Hi Rounikc G I checked with verify disk and found 4 errors as I mentioned before. OK I am going to click repair permission button. I use Mac G5 quad and OS was 10.4. I have the original OS 10.4 disk which came with G5 when I bought. I had Logic Pro 7 installed before this Logic Pro 7.0.1 upgrade. What should I do - reinstall the prev Logic Pro 7 or OS 10.4. If I need to reinstall the prev OS, please give me step by step instruction. I need to back up most of my Logic and Final Cut projects so please give me step by step instruction for backup as well. I have an extra 250 gig external lacie hardrive. Thanks for your help. Tulu

Hi Tulu, in the Disk Utility program, select your Macintosh HD hard drive and press the repair disk permissions. I always do it twice too to make sure it comes back clean. In reality, verify permissions doesn't do a great deal apart from tell you you need to fix stuff.. so you may as well go straight to repair disk permissions. Have you updated your quicktime though.. you didn't mention this.

.. the same goes for running the software update too... top left corner of your screen, click on the blue apple and select software update. Always run this twice as some downloads are hierarchal... as in you have to download one update before you can be eligible to down load another.

Are you trying to burn an audio CD with an audio file at 48000hz? If so, there will quite possibly be some distortion because CD-audio can only support 44.1Khz. When bouncing your audio file from Logic select 16bit and 44.1khz and check the 'dither' checkbox. If you don't need to listen to the audio file on CD but just use the CD as a data CD then in toast select the data tab. OK. If the above doesn't apply to you please ignore it. To back up your important files and folders from Logic and FCP it really depends on where you have saved them. Logic by default saves them to HD> Users > (your user name) > Music > Logic copy the project folders you've created to the external HD.... or you could use a program like Carbon Copy Cloner or SupaDuper (google these) to clone your existing HD to the lacie. That way you'll have a complete copy of your system with OS 10.4.11 and logic 7.1 on the lacie. You can then reformat your mac HD (using disk utility)and use the os x disc that came with your mac to start again. I'd recommend for the future keeping a cloned backup of your system on an external disk and performing updates once you have a fresh working (and tested) backup - so that if there are any issues you can restore your fully working system more easily. If you have any further questions do let us know. Cheers Rounik

Dear Rounic Yes I am burning audio CD. I recorded my project in 48Khz and now if I select 44.1 sampling rate in my logic, total song gets messed up loosing the tempo. Before this upgrade I used to bounce in 48Khz and even 24 bit and WAV selected in the pre bouncing window (interface) and it was totally OK, never gave me any distortion. Thanks Tulu
