I’m not sure if this is a bug or not. I’ve been using an older beta of Mixxx (2.1.0-beta1 I think) with my Mixtrack Pro 3 for about two or three years. It’s had random glitches here or there, but no real problems. On Saturday everything was working fine. I went to use it on Monday and the right volume fader would phyiscally move but it didn’t translate into Mixxx. I tried it in Serato DJ Lite with the same issue. I brushed out the fader path several times with a soft, clean paint brush; blasted it with compressed air, and cleaned the contacts with rubbing alcohol. Best I could get was about 50% travel down in Mixxx.
Thinking this is clearly a hardware issue, tonight I fired off a message to Numark. After that, I figured I’d give it one last shot and tried it in Serato. Full volume range, of course.
So I decided to upgrade to the current version of Mixxx, thinking now this is a Beta issue but the problem still exists. By using the Learning mode under the controller profile, I was able to get Mixxx to re-learn the volume control to an extent - but I’m still getting about 15 to 25% volume in Mixxx. To bring it down to 0% I have to use the mouse for the last little bit.
Has anyone come across this before? I’m not so sure this is hardware anymore, but why would Mixxx “forget” this one thing? All other features appear to work fine.
