I have a Harmony 880 controlling 8 devices perfectly. Now I get this Music Server (McIntosh MS300 by Escient, the Fireball folks) and it works for power and all the input stuff, but the up, down, right and left arrows are a mess. Takes two clicks to get it to react (original remote is faster than stink) and going to 3,4 and 5 on the sensitivity scale does not work, nor does changing the delays and I think I have fooled with all of them. Have also tried copying the commands directly from the original remote, also NG. Anyone got a clue?
