Yup, I have been using Powertabs for like 6 years. Thats what I use to write stuff down; and even at one point I would solely use it to actually write with. But I realized that it doesnt transfer well; Whether it was actually playing the music with somebody or recording. I would literally have 3 guitars doing their own thing and it would sound awesome. Yet when I got the Reaper recording program, I would physically record all 3 guitars and their parts and it just didnt sound and flow as well. So even though I still use it, I try not to use it to write; just keep track of riffs.
