It was advertised by line6 that it would work as an audio interface.
It does not work because the crappy asio driver and the incredibly high latency makes this impossible.
The latency issue is in fact a very serious one!
It makes the audio interface function advertised by line6 completely useless!
I understand that there are limitations in technology and maybe is not that easy to create a decent asio driver for the m20d.
But that should be said in the advertising or, better yet, the usb multitrack streaming of audio should not have been included as a feature!
Line6 advertised every thing as it would be an all in one solution.
I bought the M20d mainly for live sound but then I thought, if this thing is an audio interface I'll just get a laptop and I'll have a complete studio on the go!
I had an old AMD 1800 PC with windows XP (LOL) and an Edirol firewire interface that worked like a dream.
Just figured that it was time to upgrade.
So, I sold the edirol interface and a guitar I had lain around and got a new laptop.
Now, I'm screwed! I've sold things that worked and I didn't know that the M20d would not work. It just does not work as advertised!
I'm in no condition to buy another interface now...
I strongly believe that this is deceiving advertising and I'm seriously thinking I could sue Line6!!!
