Hi there,
I contacted Ableton - and after what felt like 3 full moons, they told me to do some things like deleting PReference.cfg, repairing libraries etc.
But nothing seems to help...I also suffer from high latency with my external soundcard (post here:
http://forum.ableton.com/viewtopic.php?f=2&t=177107)
But this forum seems to be of very little help - perhaps everyone is so frustrated with Ableton that they have tired of articulating the same problems again and again (!)
FWIW, here is what Ableton told me to do (to very little avail):
First of all, please repair the disk permissions of your computer's hard drive with the Disk Utility. It can be found here: /Applications/Utilities/
Another general recommendation, please always use a power of 2 audio buffer size (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096 Samples, etc.) Some audio interfaces and even plug-ins have problems with "odd" values. The buffer size can be set in Live's preferences -> audio tab.
It's actually unavoidable that Amp is causing a higher CPU load than other Ableton devices. This is a result of the physical modeling used in this devices. But it's not normal that already one Amp devices is causing the problems you're describing.
Please check with the Activity Monitor if there are any other processes running which are consuming CPU resources while Live is running.
/Application/Utilities/Activity Monitor
If this doesn't help please try this:
- close Live
- delete the "Preferences.cfg", "Template.als" and "Undo.cfg" files (if available) from
/Users/[username]/Library/Preferences/Ableton/Live 8.2.7/
- delete the content of these two folders:
/Users/[username]/Library/Caches/Ableton/Cache/Web
and
/Users/[username]/Library/Application Support/Ableton/Live 8.2.7/Database
- delete the same files for all older Live versions
- restart Live 8.2.7
Note: this will reset Live completely. Your template set will be erased (if you have one), audio and MIDI hardware needs to be setup again in Live's preferences. Also plug-in support needs to be switched on again
Note: the user Library folder is hidden by default on Lion. To make it visible press and hold the “option/alt” key, and you can choose “Go to Library” in the Go menu of the Finder.
