For Narration Too

I recommend this app for those learning Hebrew Torah. There are some excellent voice recordings available, but they’re too fast for beginners. I started listening with Mimi Copy at 50% tempo, moved up to 80%, and now I can listen and comprehend at 100%.

Great Transcribing Tool ,

Great app

Perfect for transcribing on the go. You can use any music that you own and loop, slow down (up to 50%) I use this for transcribing solos and songs often and I have never had an issue.

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.
