T2+Onyx FW 16/20 first recordings!

Okay, heres how it went:

I brought down the equipment to my regular club, and recorded one of the live jams we have there, which is mostly psychedelic chillout, and free jazz.

I set up my old Powerbook G4-867mhz w/1G ram, as just a recording unit, with the onyx mixer, and recorded onto an external lacie 160GB 7200rpm firewire400 disk, and tracktion 2.

Contra bass (mono) on ch1, Sitar (mono) on ch2, Ableton live drum loops on ch3 (stereo) and synth on ch4 (stereo), and CDdj on ch5 (stereo)
= two mono tracks, and three stereo tracks.

First of, I was not able to record in 24bit, all the tracks got errors. Ok, so we went with 16 bit. And it went fine. (xept I had to cycle back to the studio like a jurk to get a new firewire cable, as the one I brought did not work! :hyper: )

After the recording, I brought it back to the studio and listened to it. The first session was about 1 hour, the second was about 30 minutes, bouth in the same project.

When I opened the project, tracktion said that: "Not enough space in your temp directory to cache files" And when I looked at the local disk, it had 24KB left, yikes!!! So I deletet about 1gig of the internal drive, and changed the cache drive to the external drive. (why does it jump back to internal drive?)

I deletet the internal drives tracktion cache folder, and got an aditional 3 gig of space.

Now the project plays fine, but I get about 15 seconds of harsh distortion (unable to hear the music), every 5 minute, over the whole take. And it sits on every track. It is not visible on the wave forms in T2 though. rendering a mix to one single stereo wave, gave the same result.

I cant find out what this is... sugestions? :roll:

Did you try opening up the recorded files in a different application? If so, is the distortion still there?

If the distortion is not there, then you could try importing the original recorded files in to a new project.

Hm, I dont have another application, exept live4 which I just purcased, havent instaled it yet.

I dont want to find a workaround, I want to find out what it is, and if I can fix it! And Id like to work in 24bit also!

Thanks for the concern, though. Your point might be to look at where the problems at?

Yes exactly, whether the noise is in the files or only in the T2 project playback could indicate the source of the problem, but I don't know anything about T2 and by the looks of the mackie onyx forum the noise issues have been experienced by other users, so it may be worth reading some topics there including the one called "Holes in recording" and others.

Is it possible that you've not actually authorised your copy of Tracktion? So it's running in demo mode, and you're getting the demo distortion?
"my gosh it's a friggin hardware"

Well, actualy bouth T1 and T2 has turned to be unregistered reasantly. So I registered T2 again, but I cant seem to get T1 to re-register.. I find only two options: -buy licence, or unlock using keyfile. What keyfile? I have registered licence number to bouth t1 and t2 at mackie.com/profile/member already!!

Anyways ive got t2 re-registered, and the distortion is still persistant. Its not white noise like the demo, but rather harsh, almost digital peaking distortion.

I tried to export just one of the tracks, and play it from quicktime, and it still contained the distortion.

Of cource the output is not peaking!


I also find it strange that t2+onyx want record in 24 bit? Or could that be because it was unregistered at the time of the recording?

you may have it registered with Mackie, but that doesnt mean you "unlocked" it. You have to download the Keyfile from your user account on the mackie site.

Ah, I forgot I had to click the link!

-the distortion is still there also in T1, after re-registering.

You may have to choose different drivers from AUDIO settings page to get the best 24bit performance. If I remember rightly there are a few to choose from.

There are no drivers on mac, luckily. You can only choose soundcard, latency and sample rate.

I (want to) use my old powerbook as a pure recording device with the onyx mixer. I have a new Pentium M 2ghz to do the music.
