Rendering bug? or feature?

[Solafide]

I discovered something today by accident.

It is an annoying little bug, or a very strange feature.

Here is how to reproduce it:

1. Set up a rack that simply passes audio through.

2. Place that on a track that goes to another output besides the default (In my case spdif to my reverb unit) It would have output at 0db and input at -inf.

3. Set up a track with a wav file in it with a rack that sends audio. (input to 0db, output at -inf.) (dry is at 0, as is wet levels)

4. Now render.

What should happen (in my opinion) is that the audio being sent to the other output (spdif) should not be there in the mixdown.

Instead what happens is the volume on your input level in the rack is added to the mix.

So if you had some reverb on a vocal, when you render the vocal is much louder than it should be.


If you press mute on the return track it comes out normal. So I guess it is easy to work around - it just would be nice if this diddn't happen.

Today I rendered 10 songs for a client, went to start mastering and all my levels were messed up. It took me a while but I figured out that pressing mute on the track that is routed to the reverb unit fixed everything.

I can't see this as being an intentional feature? Audio being sent to another output should not effect the audio on the main outputs - and if it is intended to work this way it should effect playback as well as rendering.



Since I have been using outboard gear (thus multiple outputs) I have noticed alot of strange behaviour (like the master effects sections gets parralized with some effects, and at best is unpredictable)

I hope these are being addressed for the next release.

I've noticed too that if you render a song to a file it renders my AUX return tracks to the file as well ( which are on different stereo outputs). I think that it should render the songs only from your main or default outputs. Or that you should be given the option to render down from all or some outputs. I just have to mute all the AUX return mixes to work around this, but if I forget to do that, it's another 5 minutes of waiting for it to render again.

This would be the same issue.

but thats a good thing? isint it?

i use multipul outs for space in the mix, & before i had to render each output to a seperate file then mix the (in my case 4) files together again

if your ruteing to a external effect then you want a live recording of what you here, so send the master out from your mixer to a input in T2 then record that input as it plays through

thats what i do

or solo each output & render to seperate files

I can see the problem here. I think idealy Tracktion would offer an option in the export dialog to only export the default output or all outputs. Would that solve it for everyone?

It would for me. I would really appreciate it!

I do this by time. With the rme fireface it can be done very simply all right within the "total mix" software - so I don't even have to use cables.

This is where the problem comes in that I described above. If you forget to mute the aux returns that are going to the external effects, your levels get all messed up in the rendered file (but not in playback).

cant you send what you here from total mix to a asio input & record in real time (as it plays) intill this gets added?

ps. my emu1820 has somthing called patchmix witch i thing works similer to total mix
