Title: Processing Mixpre6 multitrack recordings
Post by: Duncan on November 10, 2019, 08:35:39 AM
Sorry for asking a question that I'm sure has been covered but I've just started doing 4 track recordings with my MixPre6 and need to learn how to mix these down
I'm planning to more from Wave Editior/Triumph to Reaper on Mac as that seems to be a well regarded DAW.

Could someone tell me or point me to a place that tells me the process for changing the 4 tracks into a nice stereo matrix.

Cheers
Duncan

A starting place - Use wave-agent to extract two stereo files (each set of microphones). Drag each into reaper and adjust the volume for each (and time align if necessary) within the mix.

Oh OK cool
I didn't realise that it was that straight forward!!

Is there anything about getting it from two stereo tracks to one stereo output from reaper that is not as straight forward?

Thanks for the replies

There are several ways to do things. My suggestion is to just set up two stereo tracks going into the master bus, and set the volume of one track relative to the other in the ultimate mix. Once you have a mix you like, you render it intoone stereo file. You could also create a left and right track for each set of microphones and mix the four tracks instead of two stereo tracks - you could pan channels as well as setting the volume of each of channel relative to the others. For many tracks, you can create other busses and send tracks to busses before they go into the master bus (ir all vocals into a bus). I've only done mixes of two sets of microphones, usually a SBD and on stage microphones. In this case, you also have to time adjust, which I do by nudging on of the stereo tracks relative to the other.

Create stereo tracks by using wave-agent to save tracks from the polyway into a file.

Drag stereo wav to the track srea on the left of the reaper screen

Set volume for tracks using the controls at the bottom - master track, track one and track two in this case

Open render dialog and make sure bitrate is what you want - in this case I recorded at 24 bit and am rendering to 24 bit

Thanks for this I've given it all a go and it all seems good
The last question I have is does Reaper automatically place the two left channels (from each Stereo track) to the left channel of the master and the right channels to the right master

i wonder when they will be upgrading it to work with 32-bit float files

It never even occurred to me to question this. As far as I know it does. You can always create four tracks and pan them yourself.

I did a quick test and can confirm that Reaper does place the two left channels (from each Stereo track) to the left channel of the master and the right channels to the right master
