Sorry if this is a silly question but i was wanting to record multiple channels of audio out of Max and thought that the simplest way would probably be sfrecord~, therefore, i would need to use more than one instance of the object simultaneously.

Would this work? Is there a limitation to the number of files Max can write to disk?

Or would it be better to just rewire into Ableton and record in traditional multitrack mode?

Or i could use soundflower to send the audio somewhere else. Though realtime monitoring might be an issue if i went that way.

It depends on the output format you need.

If you want a single multichannel file, you can simply specify the number of channels into sfrecord~.

Otherwise, if you want independent files as final result, you can use more instances of sfrecord~, I think the only issues would be: finding a comfortable method to choose the filenames (maybe usinsg [sprintf]?, and syncing the start of recording (In Max, there are no simultaneous events, so the recordings won't start at once, but we're talking of microseconds, so you needn't worry).

But, if for some reasons, you're concerned about perfect timing, and assuming you have enough RAM, you can build a patch based on buffer~ and poke~ and sync the recording time through poke~'s second inlet. Then send a "write" message to the buffers after the recording is done.

That method with the buffers sounds like a more sensible option.

*Edit: Just one thing i noticed after checking your patcher, what if i don't know the length of my recording in advance?*

Can you use more than one sfrecord~ at a time?
