Hello listers, I am having an unusual problem and hope someone here has some ideas about how to fix it. I purchased an m-audio fast track pro from dancing dots to use with sonar and cake talking 8.5. My korg synthesizer keyboard is connected to it via midi in and out chords. The fast track pro is connected to my computer via usb ports. I am running sonar 8.5, cake talking 8.5 with JAWS 11 and windows 7. I don’t think this is relevant but I also have JAWS 15 on my machine with the new vocalizer expressive voices that I use when I am not running sonar. It was running with no major problems Tuesday evening. Wednesday evening I tried to pull up a project to work on but I couldn’t get any sound from my keyboard. I did have sound coming from the mixer and I could hear everything that was already part of the project. First, I made sure nothing was muted or soloed, nothing was. Next, I checked the physical wires to make sure the midi ports were connected correctly, they were. After that, I exited my project and went into a different one. The same thing occurred, everything from the pre existing project could be heard, but nothing could be heard from the keyboard. I loaded 2 more projects with exactly the same results. I turned off my machine and restarted everything with exactly the same results in all projects I tried to access. Next, I went into the options menu found midi devices and made sure that my fast track was checked, it was. Friday, my sighted husband informed me that we were receiving a “TBIA invalid data” error from windows that came up before JAWS even started speaking. So I do not know how long I have been receiving this message. My husband tried to research m-audio and learned that others using m-audio products were having similar error messages about the drivers not being compatible with windows. We tried calling them but they were away for the holidays plus I don’t know where the registration codes are and don’t want to pay for new ones just to get help. More internet browsing taught me that problems exist when new sound devices are added. I added vocalizer voices, probably not relevant, and my daughter installed the latest iTunes, also probably not important. We learned that one possible solution is to do a system restore. We tried that and the data error has gone away, but the problem with the midi still exists. Does anyone know some more ideas about how to solve this? Thanks ahead of time. Barbie
