I made a simple macOS app for adding the tempo metadata into WAV files so that the TP-7 can read them and send midi clock from them. It typically only has this functionality for tracks that were recorded on it, but I wanted to be able to add it to any track.
Feel free to test it out with your tracks. I’ve only tested it with mine so I’m not entirely sure how bulletproof it is yet.
This was surprisingly challenging, had to get dive into the hex code and figure out which bytes were tempo-related.
