Is Ableton fixing PROBLEMS with Core Audio????????

Why can't Live disable unused I/O's in audio prefernce using Digidesign Harware and Core Audio in OSX? Why can't Live change Buffer settting on Digi Hardware in OSX? Is Ableton working on fixing this problem? 22ms of fixed overall latency is pretty noticeable! And having all 16 I/O's on my 001, the 002 or the 002(R) or TDM hardware put a way to much strain on out CPU'S. So Ableton what's the story? Can we expect this to change. AM I GOING TO BE STUCK IN OS9 FOREVER!

have you asked digidesign? after all, they're the ones who write the coreaudio drivers for digidesign hardware.

I've been complaining on both forums. No one from Digi or Ableton has replyed. But I'll head over to digidesign and focus my beef over there. I'm not sure who needs to fix this problem but some needs to and fast. There are a whole lot of people using digihardware(Mbox,001,002,002(r) 96I/O, etc.)Who are going to be pisssed when they switch from OS9 to OSX. Becasue A) The performance sucks because you have 16 or 32 I/O's enabled at all times that you can't turn off. B) A permanent buffer setting of 512samples and 22ms of overall latency! These are REALLY BIG PROBLEMS THAT SOMEONE NEEDS TO ADDRESS. If it's not Ableton than by all means some from Ableton please say something. Even if it' is Digidesigns problem just say so. [/b]

if all your audio application experience the same thing with the core audio, then I think, that it's up to digidesign to fix that. I notice i have the same thing happening with the out inputs number on my RME driver, (i can swith buffer size though, and with the dsp integrated, i don't have any latency so that doesn't bother me), so maybe it's up to apple core system...

It's up to Ableton to add the feature of being able to disable unused inputs/outputs. You'll find this subject mentioned in previous threads on this forum e.g.
http://www.ableton.com/forum/viewtopic. ... highlight=

Ableton have said they will do it, but not when.

thanks for the info.

This is a pretty big setback to OSX and Live jiveness. I hope Ableton can fix this pretty soon. I really never need more than 3 live in's and 2 out's at any given time. So to have all of my 16I/O's active all the time sucks the life out of my powermac.

New user here; first thread I searched for was this!! Hi all and thanks.

Yeah me too. Dang it runs like a champ even off the internal Ti667 drive thru the internal outputs, but no go thru the 002r with or without a firewire drive in between running the audio... it croaks as soon as the going gets tough on more than a handful of tracks (maybe 6 to eight). The latest digi coreaudio driver does nuttin to solve it apparently.

So all the outputs being wide open is the problem?

Yeah having all the I/o's active puts a lot of strain on your CPU. Hoepfully ABleton will have a fix soon.

i have a feeling it is digidesign that is at fault here... i have a motu firewire souncard which uses CoreAudio drivers and i can get < 1ms of latency with it on a PowerBook 800. and i have never seen a control panel that lets me disable any inputs or outputs.

i don't think DigiDesign was too thrilled when Apple Switched to CoreAudio. in fact, IIRC, Digidesign have been the slowest of the big mac sequencer houses to port their software to OS X.

hope it gets fixed soon,

So would it be normal, at this point in the game, to have a Powerbook G4667 with PT LE / 002r, and LIVE 3 rewired in, and with 16 tracks (8 stereo) in LIVE or recording to any PT tracks thru rewire to a separate FW drive, for it to be taking such a $h!t that I have to bounce one stereo track at a time?
Just wondering....

So Ableton any news on a fix for Core Audio???????????????

I would love to able to ditch my OS9:) I would love it if Live behaved the same in OsX as it does in Os9:(

I use Live in OS X 2.8 with a PowerBook and a MOTU 828 and it works like a charm............

Sounds like the problem is on your end bro

I have a Event1 EZBus that uses CoreAudio and CoreMIDI drivers. I haven't had problems since, after upgrading from 10.0 to 10.1 a couple years ago.

Ok here's the scoop I found out after a ver helpful and informative call with Ableton in Germany (Thanks Man!!)

Ableton is not the problem with Core audio. Even if the provision was in there to switch on and off your analog and digital ins/outs, Digi doesn't support them - there is no place for ableton to internally 'connect' to since the virtual 'ports' aren't there from digi in a core audio sense.

However, run in DIRECT I/O and you can get pretty decent performance and the ability to turn on/off all your 002r I/O's. That's what I'm doing now and if you launch Live with it set in direct i/o it is pretty stable.
