had a late answer from roland support in the us regarding the rc50....but i have already let the matter go in my mind....still interesting tho.......he sounds a bit worn down by my questions... "The RC-50 has had a few quirks in its short life. One, a short skip in the audio playback upon using it live to loop, was addressed in an update. These updates come from Japan where the product is designed, developed and manufactured. When they get to the US, they are complete and ready to go on the shelf. If they need fixes, such as the RC-50 needed, it requires us to contact Roland Japan and ask their engineers to stop the development on upcoming products and to turn their attention to developing this software update. Needless to say, it can sometimes be difficult to convince our parent company that they NEED to do something for us. Although we here at Roland US seem like we own and operate the entire Roland world, the real truth is that we are merely distributors of the Roland brand here in the US. We are the Guitar Center that ONLY sells Roland, you could say. Anyhow, long explanations aside, this is the reason behind the "That is the way it works" answer you seem to keep getting. We don't HAVE engineers here in the US that we can tell to "get on it" or to devote to, what we consider, an important update. We don't have a way to fix this problem you are having and it seems that we may not have a way in the near future. We were very lucky to get the one update we did receive and it would seem that there are no more coming down the pipeline. I realize this may be a little disillusioning for you, but I guess sometimes the truth can do that. In the end, if the pedal seems unstable and unusable to you, it may not be the product for you. Again, sorry for the lengthy message, but you seemed to want a rock solid answer. This explanation is literally THE best answer you can get from anyone in the entire US on this product. I hope that this helps answer your request.
