Sorry, a bit off topic but...

I used to have the MRS-4. It was good for what it was back 14 years ago, but it was a pain transferring files & formats.

I now have the Zoom R8 which is much better and it will transfer straight to my laptop and also has an interface.
I know there are heaps better set ups and gear, but I'm pretty crap as an engineer. It suits my needs well enough.
Use the R8 as a capture device and mix with Audacity on the LT. It has very good drum patterns and sounds which is a bonus.
