Reverb not playing in Apple Music

It sounds like there might be a compatibility issue with how Apple Music handles reverb effects in WAV files. It's possible that Apple Music's playback system doesn't fully support or interpret the reverb effect applied in Reaper.

One potential solution could be to try converting the WAV file to a different format that is better supported by Apple Music, such as AAC or MP3, and then see if the reverb effect plays correctly. Alternatively, you could try exporting the audio from Reaper with the reverb effect baked into the audio itself rather than relying on the effect to be applied during playback.

If the issue persists, you might want to reach out to Apple Support for further assistance or consider posting your question on forums dedicated to audio production for more specialized help.

I'm glad to hear that converting the file format worked for you! Posting about your experience on the Reaper forum might help others facing similar issues. It's always great to share solutions with the community.
