Master Volume Problem

Hello, I have this problem where the Master Volume just turns off? During "Play" when I would hit the STOP, the master volume fader would turn off?
It's an intermittent problem, where it doesn't happen all the time. Weather I have one track or many tracks with or without plug-ins. I have checked my software (Sonar producer X2) midi settings & properties, my Computer settings and everything checks out! I'm using the "MCU Pro" surface controller 
with the latest Firmware: v4.0.2, I've Uninstalled and re-installed both Sonar (up to date), and MCU Pro. I have also checked all the Microsoft updates, and that's not the problem, because it's been going on for a while, and I've just been putting up with it.

I could be missing something, has anyone ever had this kind of problem? If so, could you Please give me an idea of which direction I should go?

Thank You

Mike.

Hello Kalle, thank you for your response! "Yes" when the master volume goes to 00 from Unity, the keyboard space bar does the same as the stop button on the MCU Pro control surface! Like I had mentioned this is an intermittent problem, which I've also tried other control surface (SSL, Tascam, Roland), same result. I've done diagnostics on my computer and that all checks out and running perfect. I have done the Bus-Track and that doesn't effect the master volume. I've tried all that you have suggested, and still the same.

This has been going on for a couple of years or so from Sonar Producer 8 to X2, I've tried contacting Cakewalk, I've tried downloading to another computer, which this is also brand new (Making three different systems).

I don't want to go to another DAW software, I just moved away from my Protools HD, which I like the Sonar more but this situation has me frustrated as you most know during recording sessions, things move quickly without "all of a sudden" the master volume would move down to 00? can't punch-in when, every two or three presses of the stop button, turns off the volume?

Thank You again for you suggestions, I might have to consider other options.

I think he must mean Master Volume (CC7) on synths. Sure sounds like the "Zero Controllers" setting that Kalle mentioned. It might seem intermittent if some tracks have CC7 messages in them for the related Controller Seachback function to find. If not... silent synth syndrome.

Hello Fastbiker, Yes! when I have the master volume at Unity, which most of the time I don't touch, other than Play and Stop, to go over the previous part, when I press "Stop" the Master Volume slider (also audio volume) goes down to zero, then I have to move the slider back to Unity. 

I've gone back to all defaults on the Sonar software, I've tried other surface controllers, and computers (dedicated stand alone no internet connection other than Cakewalk downloads and updates, No Microsoft updates to interfere operation) and still the same situation. Also being intermittent my first thought software corruption, but this has been going on for a couple of years since Sonar Producer 8 to X2? And yes Mel-ware, Virus software etc have all been checked out, No problems there. All the computer's components from CPU have been completely checked out, (CPUID) from Intel Q6600 quad-core, 8g of ram etc. Maybe I need a more powerful system?

Thank You!

can you post a pic or mayve a screencast showing the problem??

yeah, use the print screen button on your computer and save as a jpeg or gif pointing to which sliders you're talking about.  
now that i read your post again i'm getting the feeling you're talking about your audio interface volume sliders.
screencast is done using a tool like smrecorder, which is freeware. http://download.cnet.com/...-13633_4-75332290.html

then, you can do stuff like this and post to youtube...  takes a lot of the asking for clarification questions out of the factor...http://www.youtube.com/wa...bOzk8&feature=plcp

i meant the audio interface volume sliders within sonar on the console view... not your actual audio interface. i always thought protools was abit easier to use personally for mastering and audio work but prefer cake for soft synths and fx routing.

Thanks swamptooth, ProTools LE is different from ProTools 10 HD being dedicated DSP are more solid performance wise. Work load wise there both similar. ProTools HD is very easy to work with, Sonar is simple to work with, great software! Thank you for your suggestions!
