audio recording mac

Hi, my question will seem really basic, but I'm a beginner. I can't manage to record the sounds I'm generating in my patch. I think it might be due to the sound preferences, but I've tried several possibilities and it doesn't work. Also I have "clipping" problems using FM synthesis. I'm supposed to mimic car engines. I'm in some kind of emergency, so if anyone has a clue about one of these 2 problems, feel free to explain.

Copy patch and select New From Clipboard in Max.

Just connect the out put of the gain~ to the input(s) of sfrecord~! The adc~ represents the physical inputs to your sound-card, not the outputs of your patch.
Even simpler, just use the Quickrecord patch in the Extras menu - it captures whatever is going out to your dac~ and saves in to your Max folder.
Your patch does indeed sound like a nice rumbly vintage motor, but I'm not getting any clipping unless I raise the gain~ above the 0dB level (which is approx. 3/4 full scale) which you might expect anyway.
Perhaps introduce some more high frequencies as the revs get higher, to simulate the rattle you get with most engines ...?
Cheers
Roger

Thanks a lot Roger for your advices ! Well this patch is part of a bigger program, where other sounds interfere, but I had thought about adding higher components indeed. I like the round and vintage tone though. The clipping actually occurs when the speed gets really slow, or around 370. I think it has something to do with the synthesis itself, don't you ?
