Thanks KC,
I did see that mentioned in the forums, and was able to test mine at a distance of about 1-2 feet by putting my dongle at the end of my longest cord. inches tho… wow. I will try that today! I actually just now got back from buying a couple of extensions and a midi interface to reach my board. I tested last ntie with a couple of short midi cords and it’s my best option so far, it STILL adds a weird high pitched whine tho… but it’s noticeably quiter yet than my modified usb cable.
