I have a few devices for which MX Editor had no codes, so I had to teach it the codes. I can get everything to work well except the volume controls. On the original remotes, if you press VOL +/-, they send out a continuous command that quickly ramps the volume up or down. But the learned volume commands only send one command at a time, even when you hold down the button. It takes forever to adjust the volume this way. Is there some way to fix this?
