I don’t often post here but have been lurking around for a few years - However I am now at a situation where by DAW setup is no longer usable in any great capacity and I need your advice/guidance before I think about spending money.
I run a early 2011 MB Pro with a 2.3ghz i7 along with 8G RAM and a OCZ 512MB Vector with 2.3G i7 with Cubase 7.5.10 & Reason 7 [Plus a selection of VST’s]. Outboard gear is a Propellerhead Balance audio interface and a Virus Ti. For my display I use a Dell 2560x1440 WQHD 27" monitor driven via mini display port to a dual link DVI adaptor and the laptop screen.
Over the past few months my setup appears to seriously struggling in the performance department. By performance I mean that I can not run anymore than about 5 or 6 VST tracks in a mixture of Virus external patches and internal VST patches without cubase grinding literally into a stumbling jittering mess. I have all sorts of audio glitches and random sounds being produced and the VST meter showing it’s maxed out in ‘real time peak’ pretty much at around 90% - Even tonight I created a basic two track project using Halion and video’d the problem which is here: http://www.sync24.com/steinberg/IMG_1602.MOV as you can see from the video clip cubase is pretty unusable due to the glitches and general poor running of the code.
Other issues: Hanging cubase video service processes [videodecode/videopreload] - these report as ‘not responding’ in the OSX process table. Killing them from the OSX shell has no affect.
What have I done so far? I have pretty much done everything I can think of to eliminate the problem but it still exists. [By the way I am a Linux engineer by trade so I know my way around the OS and the components]
Re-formatting my SSD, turning trim on [and off], validating the disk IO using Black Magic Disk tester [IO Is circa +400MB per sec across the board]. A fresh re-install of 10.9.2 - recovery of apps from Time Machine, rebuilt kext caches, removed all previous versions of cubase [was seeing this in 6,7.05 and 7.5] and reinstalled 7.5.10
Repaired OS FS permissions, dug around in the system logs. Dug into the Activity Monitor to find any rouge processes using IO, mem or CPU
Moved the virus AND the Balance Interface to different USB slots using onboard laptop ports each time as well as a powered USB hub [Belkin USB 2 5 PORT]
Reinstalled Virus 5.08 firmware
Running cubase as a brand new user.
Reinstalled Plugins ETC
- Cubase and core 2 audio are cpu bound [however this is not evident from the activity monitor]
- The onboard display GPU [AMD Radeon HD 6750M] is not capable of driving the monitor and the LCD display and the graphics offload to the CPU is causing the problem
- The balance audio interface is broken [however, the audio problems only appear in cubase]
- Cubase and/or core 2 audio are not playing nicely together = bug in cubase
By the way - all other audio programs [such as reason 7 with lots and lots of tracks or adobe auction] work perfectly.
Sorry for such a long post, I wanted to get all my bases covered before I posted here.
Before I splash on MacPro - has anyone got any other suggestions on things to look at or try - I really am stuck now and I want to make sure I am 150% certain it’s my hardware.
Thanks in advance
