- Especially one project is teasing me..
When I load it up the sound is distorted and kind of stutters.. It stops when i switch the audio engine off, and back on, though i do not see this as a long time solution...

This has been going on since i got live 8 suite and my mac 2,66 ghz processor, i have a lowbudget soundcard presonus firebox

I do big projects (i make soundtracks and such with a lot of audio samples, a lot of drums and a lot of bass ) In the mentioned project i have 8 audio tracks, 9 drum tracks, and about 20 live instruments... This might be a lot but it is my style, and id like to find a way to make it work

Any Ideas?

- try increasing the buffer as the track count increases
- try asio4all driver instead of the stock one (oops, sorry you're a mac)
- see if any plugin is causing that

I'm on a Mac Pro and I have an Apogee Ensemble (not a cheap unit at all) and I have had this happen to me more than once. One time it was so bad that I couldn't fix it at all. I had to format and reinstall the Mac. I never figured out what was plaguing Ableton.

It happened again serval months later but was some how resolved by updating to the latest version of Live.

It was because of all this I started to question even using a Mac at all, I thought with the Mac I should be free from these kind of lame ass issues. I would switch to PC in a heartbeat if only my stupid sound card had drivers for Windows.

Good luck. Let me know if you get it fixed.

No, he's not. Clearly, Lives audio engine has problems, and is inferior to that of PT. :D :) :( :o 8O :? 8) :lol: :x :P :oops:

To op: How about freezing some of those 200 synths and drumracks or flattening? Is HD full? That causes problems as well - try external HD to drive your projects from.

I´ve tried increasing the buffer - it does not help a thing - but you´re right its the same stutter as when the buffersize can not drive the lot

Ill try see if I can find a different driver - thank you

Actually I also started questioning my dedication to mac untill I saw this happen on pc´s aswell (never as bad though). I think its somewhat the driver for the soundcard and the sound engine that has issues. But its weird since mac is so good at integrating drivers.

Ill keep it up. Thank you for your response. Ill let you know

HD isnt full. It also happened with my old mac, but got more severe when i got the new one. Ableton was the first thing installed and the only thing for a long time, so its more than a full HD.

Ill definetly try freezing/flattening... Though I think its as you say its the audio engine thats the bad guy, but i just need it not to start stuttering, especially in live situations

Thank you for your response!

These forums clearly need a facebook-style "like" button.

I often have to switch my Audiofire12 on and off when it starts crackling upon playback in OSX.

I think its a mac/firewire issue.

I've had the exact same issue as the OP on fresh projects with only 1 instrument and buffers of all sizes on an interface better than most people here. I'm not doing it wrong. Also weird enough is the problem was only in Live, it would play perfectly in Logic and other apps.

It's Live's audio engine for whatever reason.

Having the same audio crackling issues. Even small projects with 4 - 5 midi tracks. Have to switch audio engine off/on to make crackling stop.

I used to get this with my duet on my mini and the only cure was to switch the audio engine off and on in live.
I havent had this issue on my new iMac though. I think it is CPU related.

What version of live u using?

I'm using 8.2.1.

I unhooked the duet and restarted my machine, then hooked the duet back up again. Problem seems to have gone away for a bit. I've also e-mailed Apogee support. This problem also affected my NI Kore Controller yesterday, so I'm not entirely sure it's duet related. Things seem to point to Live's Audio engine or ???
