Massive M20d latency with Cubase 6.5.4

Hi. got my M20d today. Hooked it up with L6 to stagesource S and T. Sounds good.  Decided to use it as an audio interface with Cubase 6.5 and downloaded the latest driver.  Now I have an input latency of 525.964 ms. Output latency is 560.612 ms. Checked the control panel: default buffer size is 256, bit depth is 24 bit. in the bottom half of the driver control panel where it reads "ToneDirect & USB audio streaming" the buffer size is the middle between "Extra" and "Medium."  I tried setting a lower buffer size and changed the bit depth but was rewarded with white noise and crackles and pops.  Doing this also does not reduce the Latency readings in the "ASIO StageScape M20d" Cubase Device Setup window.

 

I am a big user of Line 6 gear, from Variax, to the toneports, kb 37, pod xt, x3, and the pod HD 500.  I have NEVER experienced anything like this with a driver.

My desktop cpu is intel i7 975 extreme, with 12 gig rams, asus pt6 motherboard and very fast ssd drive.  It works like a dream and this is the first time I've ever had any audio interface issues.  Currently the only line 6 drivers on my pc are the m20d and the pod hd 500.  I'm stating all of this to give an overview of my gear so that maybe somebody can help me figure out quite quickly what is wrong, and find a fix.  Anybody with similar issues? Help please, Line 6.

    This question has came up a few times. The m20d is not an audio interface and is generally not suitable for this use. from what i understand they may be working on some updates that will make it useful for this, but they are not promising to deliver.

        Me as well. It's one of the things I had assumed it could do and seems like a major ball dropped if they don't correct it.

          Indeed, I had been under the assumption that the desk would very much function as an interface given the USB output to DAW that is provided.

           

          Although, it may very well be the case that the sheer amount of DSP involved in making the M20d do all the wonderful things it does, is just too much for it to be used as a regular audio interface.

           

          And I agree, the M20d would be an even more powerful device if they are able to correct these issues.....

    For its intended purpose – as a highly flexible live mixing environment and front end for high quality recording – we are very pleased with how the M20d turned out, but it is important to understand how the audio behavior over USB works.

     

    The M20d was designed first to be a self-contained multitrack recorder. Its ability to do multitrack recording and playback to and from an SD card or USB drive connected directly to the mixer allows for high quality standalone recording of live performances.

     

    USB audio streaming to the computer works very well for multitrack acquisition of the audio channels coming into the mixer, but the M20d was not designed as a replacement for traditional bi-directional sound cards or DAW interfaces. As such, it doesn't allow for low latency thru monitoring. If you require the ability to use computer-based virtual instruments in your live performances, you'll need to connect the audio outputs from the computer into input channels of the mixer.
