Hey guys, I'm hoping someone here can help me. I have a brand new MBP (OSX 10.4.11) running reason 4. Recently I've had problems running it. When i play reason it play back as though CPU usage was high. It has a poppy, glitching, choppy playback sound.

The only change I recall doing is running my routine mac software updates, but I dont see how that would change any audio driver setting. Ive tried messing with Reason's audio buffer settings but nada.

Anyone else here have this problem> Please help!!

Have you tried running your output as ASIO?

Joe

How do I do that? Any help is appreciated

Edit>preferences>audio. Once you are in the audio, choose ASIO in the Audio Card Driver window. If your sound card does not support ASIO, then you won't see it. You can download a free ASIO, but I'm not sure what site it's on. Someone will know. I'm not sure if this will fix your problem, but you should run the audio with ASIO anyway. Less latency.

I say you run with it, everyones after that glitchy electronic sound

Haha! I'm gonna call it Reason Glitch Pop.

This is when your sample buffer rate is too low. Read here.

But I have a Mac so i don't have the Asio option. I'm just wondering where things went wrong when I never had an issue before. I've been running Reason 4 on this mac for several months then all of a sudden this happened

It's just because your Buffer Rate is too low and/or you haven't selected the best soundcard. It happens to everyone, it's not a problem.

Hello everyone!

I've experienced exactly the same problem. I have a Macbook running OSX 10.4.11 and I'm using the built-in soundcard. I've concluded that this problem is solely/partly because of a recent OS X Intel update. I've tested with both reason 3 and 4 and had no problem whatsoever just before the update. However right after the update things started to behave badly. CPU goes through the roof and playback is constantly choppy. Before it was always smooth and Reason used very little processing power as it should.

I've tried the suggested measure fiddling with the buffer size but with no success so far. It got better for a few seconds but then it started to go wrong again.

Would be greatful for any help or suggestions.
