Summary: You can download the TASCAM DR-08 manual because it is the same (except for 24 bit/96k recording) . You can also easily update the firmware with TASCAM DR-08 firmware and add the above functionality. Search for the VR-20 firmware hack and substitute the VR-10 firmware. When I turn mine on, it says DR-08. The only thing I noticed was that I had little control over the line input level (level wouldn't drop when turned down to zero).
Summary: I use this whenever I get an idea for a rhythm in my head. I just pull it out, turn it on record, and then start humming or whatever. Later, when I have more time, I can sit down and play the guitar or drum machine or piano to get the idea onto the computer. Works great for what I bought it for. It is simple to use too.
Summary: I have owned otherTascam portable recorders in past years and this one I would rate as the easiest to operate right out of the box. The other models in past years were overly complicated. This one is simple and effective to use. I purchased this unit from the "daily deals" so the price may be higher now.
