Isosceles_CAT

Hello, I would like to feed the outputs from my mixer back into my MOTU Ultralite, and record the signal with MaxMSP, while I'm playing a live set out of Logic on that same computer.

I had originally planned to capture the output from my mixer to a DAT recorder. However, due to unforseen circumstances, that is now financially unattainable.

I was thinking about the 'sfrecord' object, but I'm not sure if this would affect Logic's performance. I'm also concerned about level clipping, since the signal level could be unpredictable.

Is there a way I could insert a limiter plugin between the ADC & sfrecord object? Also, is there a better object to use than sfrecord?

I'm running a MacPro Quad (3gb RAM) with a MOTU Ultralite interface.

sfrecord~ is fine for recording, that's what it's made for. check out the omx externals for a compressor and/or limiter.

it shouldn't effect logic too much to record a stereo channel with max, but of course that depends on what else you are doing at the time. only way to find out is to test.

Thanks! I guess I'll just keep the levels coming into the Ultralite really low, and hope that the snr is low enough that I can boost the signal as required afterwards.

Does sfrecord~ store the data in RAM, and then write to disk when complete? Or does it write to disk in realtime?

Why don't you use the spdif ins/outs? That would copy it 1:1...

Like Max, Logic can't put out more than 100%, if its clipping, Logic is 

clipping already. Or do you add other analog sources?

I do add analog sources, and my mixer does not have spdif IO.

I used inputs 7 & 8 to record the output from my mixer with sfrecord~. It was actually so simple to implement that I offered to record everyones sets that night. The recordings came out well, but I guess when it came time for me to play I was a bit anxious and forgot to open a new file to record into, so my set was recorded into the ether. :(

Oh well, I've got it down for next time. Thanks most kindly for your help everyone!
