Sonar X1B (w) MCU Pro = Jerky Fader Playback - *see video* HELP !!!

Hi all
 
Please see this video  =>  http://www.youtube.com/watch?v=YlnqozJxaZc
 
I am running Sonar X1B 255 X64 + Windows 7 X64 in a Intel i7 DAW with a Gigabyte motherboard - USB is not being shared with anything else and is running at full USB 2.0 speed.
 
This is a fully clean Windows and Sonar install.
 
This MCU is a brand new one with the Alps Faders running Firmware 4.0.2.
 
Anyone have any idea what is causing this jerky fader automation playback.
 
Thanks,
timboe
 
PS:- Other than the above " jerky " issue,  the unit is operating perfectly.

    What you're seeing there is due to the update speed of the data.

    If you try to refresh the position of the faders 1000 times a second you'll soon burn out the motors.  I don't know if Sonar has a limit on the amount of updates per channel it will send, I wouldn't think so, but the hardwear will have a limit on the amount it will listen to, ignoring the rest.

    There may be a setting to adjust the refresh rate, you'll have to check your manual or trawl through any settings the driver may have.

    Hi Karyn - thanks.
     
    So, does anyone here know of a setting in AUD.INI  or  TTSEQ.INI  that I can manully edit to try and fix this issue ?

    Go to Edit > Preferences > File | Initialization File.

    Under Options put "CtrlSurfaceRefreshMS" without quotes.

    For the Value try 75, and click [Set], and test. This is the default value, it's possible that it got changed somehow. You could try dropping it down to 50 or so as well. Though it's likely there's something else going on in your system delaying the MIDI messages to your Control Surface.

    Edit: Watching the video again, I don't know if there's actually a fixable issue there. That may just be how the MCU responds. I'd try what ProjectM asked and test it with another application.

    Hi Seth

    Some news ........  I tried  50ms and the problem was still there ..... to test further, I then tried 500ms and it responded accordingly .......ie: it only responded every 500ms and as such it was very jerky and  "steppy" .... so the setting changes do work.

    I then manually edited the  Cakewalk.INI file to force it to  10ms  [ as the preferecnes box has a  50ms <-> 5000ms limit range ]  bit it was still jerky and uneven.

    Any other ideas I can try  ?

    50ms = 20 updates per second, you should not see any stepping at all with that setting.


    If the faders are still jerky, then either the data rate is just too high for the interface to handle OR its a limitation/setting in the controler that limits the faders to 5 - 10 updates per second.
