Waste if you use Apple Music

You can’t import music that you have license to use but don’t own. Waste of money for me. My son wants to use it to slow down music to learn guitar chords. Try before you buy I guess....

Worth every penny!

I've been using this app on a daily basis for the last 4 years. If you are a professional musician doing pick-up/sub gigs, you need this app. Some of the most useful features are the ability to 1) use loop markers for 3 separate sections of a song, 2) isolate left/right channel and 3) organize folders and rename files 4) transpose songs in not only half-step increments, but then further fine-tune (if necessary) in increments of .01. Those features are just scratching the surface of what this app can do for you.

Even at the lowest playback speed, this player exhibits exceptional sound quality.

I have occasionally encountered an error message regarding DRM protected content for songs I have already purchased through iTunes. I could be wrong, but I assume it's due to metadata embedded on the track. There are two work-arounds for that, in my experience. The first is locating the file on PC/Mac and uploading over Wifi. There are step-by-step instructions for doing that within the app. The other is locating the file on Mac system and air-dropping/open with mimiCopy.

I use this on both iPad and iPhone and works perfectly on both.

The most worthwhile app I've purchased and the most important app on my iPad. I would consider this a necessity for any musician. This was the first player I've used and it's easy to use and has an exception sound quality even at the lowest speed setting.

The solution I have been looking for

I have used many slow-down programs for learning music over the past few years, but have been very frustrated with most of them. Some take longer to learn and are not very user-friendly. All of them had one major flaw (IMO) and that was they would not read from my iTunes library. I had to first burn the song to a CD and then rip it back in as an MP3 before I could select a segment to slow down and loop.

I had written to Apple and asked if they would add this function as a plug-in to the iTunes player, but my suggestion was ignored.

Then, along comes mimiCopy. This does exactly what I want and is relatively easy to use. Thank you for filling a need when I needed it most! I am telling my friends about this app.
