First off what a great distro. I'm having some issues with tX and midi bindings. After mapping a set the next time i boot it most of the mappings are gone except the faders on my us-224. I am also mapping to an edirol usb keyboard. Just wondering if anyone else had the same issue and if there is a fix. Perhaps I'm I'm missing the obvious... thanks. I'm running the 32bit version on a Vaio laptop the Tascam US-2224 is my main card.
