Protools Lag Issue

[changareth]

I decided to move to PT9 from Logic and this is the error I get when I play my songs in PT9.

I only imported 5 stereo WAV files 16 bit 44.1khz and not running any plugins except 1 instrument track thats using BOOM for drums.

I tried increasing buffer size and all that but I think its just stupid coz if i increase to 1024 i will just get latency. So I'm just sticking to 512 thats the highest i'd go but then again I still get this lag and from time to time the increase buffer error. It's getting really annoying. Sometimes the track plays and when i hit space bar the song wont stop until like after 5 - 10 seconds of lag.

HOW CAN I FIX THIS? This is pretty bad. I use to run logic with gazillions of plugins and it worked just fine.

I am running an iMac duo core - Snow Leopard with 4GB of Ram and I PURPOSELY swapped back to a 7200RPM 2TB hard drive that I cloned off from my previous old HD that was 5200RPM. Although 5200 was running fine with logic I decided to switch it to 7200 for the sake of PT9. I use M-audio Firewire 410 interface.

I also tried not using my interface but I still have the same issue. I'm wondering if its my system itself that has a problem. should i do a fresh OS install instead of cloning from my 5200RPM HD?

I really dont see anything wrong with my spec it should be more than enough to run PT9. So how do I fix this god damn error???

This is an external drive, right? You're not running the session off of your system drive?

I tried both.

I tried running everything on my internal drive which is a 2TB 7200rpm HD. Problem persists.

I tried only running PT9 off my internal HD and audio files off external firewire HD which has a rate of 800mb/sec and problem still persists too..

I've pretty much tried everything I can think of. Just havent tried installing a fresh OSX without cloning my old hard drive.

You don't have to worry about latency if you're just mixing. That only applies to tracking. But with that computer you should have no problem with a hardware buffer of 64 in moderate size sessions.

What does "lag" mean?

[changareth]

Well I do tracking and mixing too. anyways basically at any setting my protools response slowly. e.g. after i start playing the song when i wanna stop it i get like a 5-10second delay before it stops. Or when its playing and Im in another window and try to switch back to my PT window it delays too as if its frozen.

I basically cant accept myself working like that. And I believe it shouldnt even suppose to act this way.

What troubleshooting have you already done? Have you been thru the Troublshooting Sticky above? It is something in your system...ff

Go into Preferences and find the Record Allocation setting(which defaults to no limit). Set it for 15 minutes and see what happens.
