Q: Frequency variations

I am editing, and then synchronizing, several sine waves for a product that I have created. I am noticing that while all the sinewaves are very accurately edited and in coherence with each other, during playback there seems to be some variation; at time entirely new harmonics seem to be present. The tracks have virtually no inserts and the CPU doesn't seem to be working overly hard. Any ideas of where to look for the problem and how to solve it? Frequency fluctuation is a product killer in this case.

Logic Studio, Mac OS X (10.7.5), 2x 3gh quad core

Is It possible that you have a randomizer engaged?

I don't think so but since I am not sure what that means in the context of Logic, where should I check?

I wasn't sure if your synthesizer (ie Omnisphere) has the random systhesis engaged. Which means it randomly does what it wants when you play. Most new soft synth have a simular program.

Thanks for the idea. No, I have no synth hooked in on this operation. The tones are generated on the computer and saved as wave files. Then imported into Logic where they are edited and so forth. The entire process uses only the sound generated by the computer. Thus I wondered if their was some way whatever internal oscilators could be overloading or fluctuating for some reason. Still stumped.

Sorry I couldn't be more helpful. I do believe Logic oscilators also have a randomizer. Good luck figuring this out.
