It's less likely corrosion, I often experienced that all kinds of jacks and sockets don't fit to each other. For USB connectors I sometimes had to remove a little bit of the isolation, because they couldn't be plugged in, regarding to too much isolation. For the 6.3 jacks here are different shapes, some are completely unusable. And as I mentioned before, the thickness of the MIDI connector pins can vary, but this most seldom really does cause issues. Resume: It was a random issue, voodoo, most of the times the cause for trouble in maintained studios. The Waldorf is a baby ;), since it can't be born earlier than 1989.

Good connector: Großtuchel In the German Wiki is a picture that does show a 2,-€ coin and a Großtuchel, because Großtuchel is very clumsy. Similar diameter as the coin, for 3 contacts only. But you can screw together Großtuchel and it has got knifes that clean the contacts, when you connect them. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
