Using PTPA Version 2019. I have a type 1 midi file I've been editing. I have loaded and saved it several times. Suddenly the last time I tried to save it the dialogue box defaulted to Seq. I changed it to.mid type 1. It saved as a .seq even though I selected .mid. I tried over and over but it will not save as a .mid. Running out of ideas I reinstalled my old PTPA V.11 and loaded in the type 1 midi file and did a simple little edit. When in tried to save the same thing happen. I selected .mid type 1 and pressed save. It had been saved as .seq just like it did in PTPA 2019. What can I do?
