I have a Tascam TM D8000. It only has about 20 hours use on it, but I haven't used it in a long time. I wanted to sell it, but when I turned it on, it gave me a midi file dump warning. I am not sure how to fix it or if it can be fixed. If it can, I would also like to see if anyone knows the best place to sell this board or even how to price it. Any info would be appreciated.
