Very interesting and making me redoubt to sell tspp
I do hear however silences and some unbalanced voice issues (original callouts to low volume). But as you mentioned, it’s work in progress.
If stern has coded same music for different modes I am afraid Pinsound can’t do anything about it. You could put two sound files in same folder, Pinsound will than randomly select one but this means you would not always have same music at same mode.
Keep up the good work and look forward to you finishing it.
