Logic Pro X and multichannel WAV file support

I recently recorded a couple of live shows to an external disk connected to a Mackie DL32R's external disk. (I had thought about connecting the Macbook Pro to the mixer and recording directly into Logic but the mixer was backstage in a rack and doing that got complicated quickly.)

This mixer records in multichannel WAV format -- all 32 channels in one file. Well, actually, that's not entirely true. Due to limitations in the WAV format's file size, it records in 7-minute bites. Logic 9 doesn't know how to deal with a 32-channel WAV file. Does Logic X? Ideally, it would be smart enough to put each channel of the file into its own mixer channel strip. (That would be a great advantage in terms of disk access.)

I have a workaround: I can use the open-source sox to concatenate the 7-minute chunks into one set-length multichannel CAF (Core Audio Format), and then I use TwistedWave to split that CAF into 32 individual-channel CAF files, which Logic likes. (Then it's the small matter of letting Logic build the previews, which takes ages.) But if I can skip all of that and just bring the multichannel files into Logic X I'd save a lot of time.

Hi,

I need to BUILD a multichannel WAV file for a multichannel player memory card.

Can I do this with Logic Pro?

Or which software you can recommend?

Thank you,

Peter

Hi Indyuser,

I need to BUILD a multichannel WAV file out of 8 audio tracks for a multichannel player memory card.

I think Logic does indeed support Multichannel Wav files since 10.1.1 ... It does it by drag & drop into the arrange page.

Run a Google search on: Logic Pro X Multichannel Wav

Also take a look at Reaper.

It does here is an example of loaded a multi channel wav file consisting of 65 channels...... If you import from the audio menu it will not prompt you for how you want the file imported - if you drag and drop from finder the arrange window.. It will ask.......

I've only imported from the audio menu -- I will try just dragging the files from the finder. For some reason, I never thought about doing that. I will try this in Logic 9 tonight.

For the record, dragging the multi-channel file from the Finder into Logic 9 does not split the file into its constituent channels.

But it does work in the latest version of Logic X (I upgraded yesterday). And it seemed to be remarkably fast, too. The only annoyance is that it created the various single-channel files and put them into the .logicx bundle. And I thought there was a way to prevent that from happening, and then I got lost in the maze of preferences.

And after playing with Logic X for a few hours last night, I like it. It works well on an aging Core2Duo iMac, too.

Thanks to all for helping.
