frequent audio "glitches" with Live 4.03 and power

amwintx · Post by **amwintx** » Thu Sep 30, 2004 6:40 pm

I am a longtime Live user and I have never had problems with momentary interruptions in audio playback until Live 4.

I am running Live on a G4 933 with 1.25GB ram, single proc, OSX 10.2.8, with a powercore PCI card software version 1.9.2, MOTU 2408 mk3, buffer at 1024, and Reason 2.5 rewired in. Even with the CPU meter well below 60% I am now having problems with glitchy playback, but the same song plays fine in live 2.1.1 (my previous version).

I have loaded Panther on another hard drive and installed only Live 4, Reason, and the necessary audio driver to get running and it glitches there too.

Anyone have any suggestions?

Thanks in advance,

Adam

Try increasing the buffer size.

I agree that should help, however, what I am really wanting to know is why I am all of a sudden having these issues in Live 4, when with everything being set the same, I didn't have these problems in 2.1.1. I am wondering if other people, perhaps using Live 4 and powercore, but not MOTU hardware are having the same problems.

i use an mbox and i get the glitches too. it happens if i have allot of plugins running.

i'll try increaseing the buffer and see what happens.

Were you successfully using live 2 or 3 with you exact setup previously?

Thanks.

I have the same thing, tracks that played fine at 80% in L3 now start freaking around 70% or so. It's like the last 20-30% isn't available, seems we've gained a few extra % at the bottom of the cpu meter in terms of basic efficiency but lost a chunk at the top when you push the app.

That pretty much correlates with what I am seeing, and I think the problem is exacerbated by powercore because it has a very high initial threshold on CPU usage, which instantly puts you closer to the new lower effectiveCPU ceiling.

So, is this an issue Ableton is likely to address or is this the inevitable march of technology signaling to me that its time to buy a new machine? I don't really need a new machine for the majority of what I do, so its dissapointing to be having these problems now, where I didn't before. I realize that I don't have to upgrade to Live 4, but of course the new features make it a pretty compelling upgrade to attempt.

yeah, previous versions didn't have any problems. never any pops or clicks. even if i was pushing the limit of what my machine could handle. the screen response would get sluggish, but the audio would sound ok.

I get rid of the glitches by decreasing the number of vst/vsti's or by increasing the latency...
I do this in live 4 and I did so in live 3

I use an M-Audio 1814 on a brand new G4 17" PowerBook, 1.5 Ghz proc,, 2GB RAM and I get the glitches too. It's more then that really. I actually have in my possession (2) FW 1814's and it happens on both. I am also a longtime user and so far LIve 4.x doesn't work as well as the others.

wow i thought it happend because my laptop was underpowerd. but if your new 17" with loads of ram has glitches. then there is no hope for people like me with older powerbooks.

That is preposterous...
There absolutely is hope...
You just need to get away from the USB hardware. I have a MOTU 828 MkII and I run significant numbers of tracks (up to 24 in one set) to all 10 analog outputs (stem mixing) to do analog summing. I have a 1Ghz PowerBook G4 (15") with 512Mb of RAM. What you need is hardware with faster firewire controllers, and better drivers. Do some investigation in these forums and you will see just how badly the M-Box has been performing for people. The same goes for the M-Audio glitching on the 17" 'book. M-Audio just has not been able to deliver what we need in the firewire audio dept. (I know, I owned a FW410 once)

I've sent several emails to support and spoken with techs regarding the problems I'm having. They have brought me through clean uninstalls via the Terminal, repairing permissions, switching to bus power only, and making sure there are no other firewire devices plugged in. Nothing helps. Another thing that really kills me is that there is apparently an issue with Panther and syncing to an external midi clock - the tempo sways like 3-5 bpm when slaving. Live 4 + M-Audio FW 1814 + Panther is a very unfortunate scenario right now. I don't know what to do. This is not a hobby, it is my livelihood. I'm in a jam!

This is simply not true. I have two machines on my desk right now, both running Panther, and CONSTANTLY using MIDI Beat Clock to sync with no BPM "swings". I have Synced up to 5 machines running Panther using my MIDI thru-box (splitter) with dead on timing. I own a good deal of M-Audio gear and used to reccomend it to friends all the time, however when my friends told me about what M-Audio tech support would tell them ("MIDI sync is broken under Mac OS X 10.2.8"

) I stopped reccomending them. The fact is they will tell you damn near whatever they have to in order to make the problem someone elses.

I'm sorry to say that I think you are right. I thought it would be a good move to go with M-Audio, given its alliances with Ableton, Propellerhead and Apple/Emagic. You would think the communication is better there, leading to more compatibility, but clearly that is not the case. I heard RME has some quality products as well, one of which is an 8-pin firewire audio interface. Any recommendations? I need something with at least 4 inputs (the more pre's, the better) and 4 or more outputs + midi in/out if I can get it. I use it in a live situation and need something compact. I'll check out the 828 now. Thanks.
