I might seem like a troll with this post, but I have to share with any of those here that might be thinking about purchaing this hardware. There is what I would call a major glitch in the function of the unit as a digital recorder, that CW customer service said cannot be fixed unless Roland in Japan fixes it--and after over a year and follow ups--Roland will not fix it.
Here is the glitch: If you're like me and need to start the recording of additional tracks over one that has been laid already from a marker you created--tough luck. The unit will only start an overdub recording at zero--completely ignoring your marker. If the song is say, 5 minutes long and you want to add a track at say, the 4 minute mark--too bad. The recording will go all the way back to 0:00 and there is nothing you can do about it.
If you don't understand what I'm talking about, then you probably won't have this issue and you're lucky. For me, it rendered the unit useless and I had to sell it on eBay for over $100 less than what I paid for it. I love Sonar--I've been a customer of CW for many years (back to v 3.1), but Roland not willing to fix this major glitch is unacceptable.
Again, if you're thinking of buying this unit--you need to know this.
Peace!
