Dave, Fine, Is it possible for you? or someone to populate the function labels the same way all the others populate the Function labels? Such as when I Identify a TSU, TSU2,TCS, Digitraxx, QSI or most any other decoder I read and have the function labels appear ? Matt seems to be using a standard format for the Full Throttle files for Functions and function labels. I know about the free form of the sound slots but there is a pattern to what Matt is doing. I move functions, function labels, sound slots whatever, whatever I need to do. As to Decoder Pro Reading the Function Pane, I understand. The REAL point in this is that I went to the LOk website, downloaded the appropriate sound file, read the data of the decoder all was correct, loaded the sound file and ended up with a non Full Throttle sound file. How does that happen. This is the second or third time this has happened and this is before evr swtichuing to Decoder pro. Rick.
