Not sure what your problem is but I downloaded Cabaret Medley,  and it opens fine in Cakewalk with the TTS-1 - I just had to change the instrument to Bank 0 and the Accordion patch and then I had to lower the pitch by -36 because the notes where out of range by 3 octaves. Sound like a cheesy accordion song now, cool.  

If your not sure about using midi files you can OPEN any midi file with Cakewalk and if there are NO outputs selected in Midi devices in Preferences then the TTS-1 will load and play the file. I then opened it in PVR which quickly explained the lack of sound as I saw it was playing up in C 10 range. 

I have tutorials on using Midi if you wish to learn how to edit the files.
