Click the pause button to pause Drag the slider to rewind
Most music pause projects I've seen either set the pitch effect very low to pause (but that's slowly drifting), or stop the sound and set the pitch effect to very high when unpaused (but then you have to wait for the sound to reach the playback position, especially for long sounds). This project uses 3 sounds: One sets the pitch effect to low and is a little behind the playback, and when unpausing it sets the effect high to quickly reach playback position. The others set pitch effect to high and replace the sound when it drifts through the playback position. I borrowed the music from @RokCoder's BBC emulator: https://scratch.mit.edu/projects/531881458/
