Good morning all, could someone possibly please help as I have a niggly problem that’s driving me mad.
I have just bought an iMac (spec below) and installed Cubase Elements 7. I am up to date with all drivers and have the latest OSX (Mavericks) installed. My hardware is an M-audio Fast track ultra 8R 8 channel USB interface.
It all works lovely, apart from every now and then, totally at random, I get a burst of crackles for possibly half a second or so, once every few minutes.
This is not affected by processor load, buffer size, or graphic load (still does it with the screen minimised). I’ve turned off wireless connectivity with no effect. I would turn bluetooth off but I daren’t in case I lose my mouse and keyboard and can’t get back in to change it.
I have checked all mains connections to outboard equipment just to be sure. I can play CD’s and MP3’s etc all day with not a crackle in sight. I’ve also noticed that if I have heavy reverb selected, the crackle also has reverb on it which would suggest it’s the input side of things rather than the output.
The processor load, depending on buffer size, is at worse about 15%, at best 5%. Even at silly buffer sizes in either direction it makes no difference to the crackle.
Is there anything in the OSX setup I can alter to prioritise resources to Cubase? I’ve tried running after a cold start with no other software running with no change, and I’ve tried it with mail and Safari running in the background with no change.
I’ve tried changing Audio priority to boost, turned off multi processing and ASIO guard, and turned off adjust for record latency. I’ve tried different sample rates and bit rates.
Any ideas? It’s bound to be a daft check box I’ve missed somewhere!
Does anyone have any settings to optimise my iMac for Cubase use? I’ve read loads of articles that are ambiguous, but surely there must be one prime setting for my machine? And yes, I’m running Elements 7 64 bit, version 7.0.6 build 2231.
I’d like to run it at the maximum quality my hardware allows (96Khz 32bit) with the best buffer size I can get away with.
It’s worth pointing out this crackle happens when I’m just playing through, not even recording, so I don’t think it’s disk related. The bar graph doesn’t even move for the HDD even when recording and playing back several channels at once.
It works beautifully apart from this annoying crackle. Can anyone help, please?
