Music Speed Changer Pro Customer Insights

1. (09/04/2019)I've been using this app for awhile and it always played an .mp3 file to the end and looped it if you selected loop.Now it just shuts off after 10 minutes of a 32 minute audio .mp3 I keep playing.It also never registers itself on Android as an audio player and it's impossible to select it as the .mp3 player for your phone.It never comes up on the "open with" menu and now with Android 10 ,in settings, installed apps, MSC, open by default all options are greyed out.This is a disaster.i change my reveiw from negative to positive.

2. Thanks.I have used this for 2 years and I have loved it so much but recently it's not letting me open any of my files and it keeps telling me to either open and close the app, and no matter how many times I do it, or how many files I pick it still wont let me open my music.great way to learn how to play songs on whatever instrument.

3. app is awsome for practicing songs at slow speeds until ready for full speedThe app does not let me save a certain section of an audio file.

4. Hopefully it'll be back soon!This app was the best out there and i had it since 2014 and now this year this month when I started using it on my Samsung Galaxy s10 the music will play and then shut off on lock screen.

5. It just suddenly stopped loading files, even though it's been working great for literally years.

6. only issue that started recently is that music keeps cutting out of phone is locked but starts up again after unlocking.

7. This app is as good as it gets, although I haven't researched alternatives.I have loved this app for several years, but it suddenly stopped working.

8. So easy to set loop points, change tempo, and learn every note of a specific part of a song.Good app.

9. other than that great app UPDATE: App has been updated but still having the same issue.

10. I did get a response from customer service, but I've emailed twice since my last response because I haven't heard back and I need to use it, and no reply.

11. But if it could be updated to where it was working on and off screen again I will definitely give it a 5 star rating.had this app for a while and i love it.
