CPU max out in T2

[Patrick9]

Oh dear.

A mix which was fine in T1, now maxes out the CPU in both T2 and T1. What has happened.

maybe you're using 64bit

maybe you're using 64bit

Just got back in and checked - I'm not using 64bit math while mixing.
(I guess that is the setting you are talking about) so I need to think again.

You checked samplerate as well? I once tried it at 96000 and right away my cpu was maxed (not with Tracktion btw). Maybe other things happening at your pc? virus scanner, mail download? (I don't expect you to make that kind of mistakes, but it happens to me, once in a while).

Maybe disable the VST's one by one to see which one has the problem?

Thanks Hans - it was a sample rate mis-match. I had the sound card at 9600 and the mix, was 41 or 48k. Sorted.

dumb question here.... wouldn't that speed the track up ???? I always thought it would.... or can you simply mix samplerates nowadays???

never tried it but always asumed it wasn't possible

[djsubject]

not if he was using vsti's & not using audio

if it has audio in then TBH i dont know

I'm not sure what is happening here myself but yes - 9600 does slow the audio (I didn't realise at first because of the general distortion). Setting the sample rate to 41.1 on my omni-studio usb cures the problem. The cpu hit is still high, but it doesn't max.

Thanks guys.

Tracktion sample-rate converts behind the scenes, if it needs to.

one of my favorite examples of Tracktion's superiority over most other sequencers, is the 'random wav file test':

Pick a wav file at random from your audio drive, and drop it randomly onto your sequencer's arrange page, without looking where its going.. in Cubase (for example) odds are you will get an error message such as 'no audio files on MIDI tracks' or 'no stereo files on mono tracks' etc. In the unlikely event that you happen to drop the file onto the correct type of track, if its at the wrong sample-rate, it will play back at the wrong speed.

Do it in Tracktion otoh, and it will just work.. the only thing you can get wrong is to land it on a track that routes to a MIDI destination, and this won't throw up any errors: you just won't hear it until you route it somewhere that makes sense. Its much more civilised IMO.
