MyTunes Pro HD includes two mixer modes—Party Mixer and Workout Mixer. The first will take any playlist or group of tracks (in an album, for example) and rearrange that playlist so that it matches a “groove” that you’ve set up for the playlist. For example you might tap Party Mixer and then choose Rise. This should rearrange the playlist so that mellower tunes are placed at the beginning of the playlist and harder driving tracks appear later. Cycle has an “M” pattern—so rise, fall, rise, fall. I tried this feature with a couple of playlists and I’m not entirely sure I agree with the app’s assessment of just how groovy each track is, but it’s still a fun way to put tracks in an order you might not have thought of.

I’m more leery of the Workout Mixer. The idea here is that you tap out the tempo of your workout in beats per minutes (so tap 1, 2, 3, 4 to accompany your footfalls on a treadmill) and the app will adjust the speed of the tracks in the playlist to hit near this tempo. Personally, while I may not be persnickety about enhancements like Wow HD, I’m more particular about a song’s tempo. Some tracks just don’t sound right speeded up or slowed down. But then I don’t listen to a lot of the music that people play during their workouts. If you listen to club music while sweating away at the club, you may find the feature helpful.

And then there are the transitions. Tap the Transitions icon next to the track information area and you can choose from a handful of transitions—the effects used to move between one track and the next. Some are fairly standard—a crossfade between one track and the next, for instance—while others are edgy and yet others something that’s cute one time only. You can audition transitions by playing a track, selecting one of the transitions, closing the Transitions pane, and then tapping the Start Transition button. In a little over 10 seconds you’ll move to the next track using the transition you chose.

If you’ve configured your iPad to use iTunes Match (you switch this setting on the Music settings screen), MyTunes Pro HD will display the contents of your iTunes Match library in the cloud. Regrettably, this is about all it’s good for. Unlike with the Music app, you can’t download multiple tracks with the tap of a button. Rather, you must tap on a track, tap through a dialog box that tells you that the track is downloading, and wait while the track downloads. Unfortunately in my testing, that track didn’t start playing automatically and the icon that indicates that the track has finished downloading didn’t always work properly. So you keep tapping Play until it eventually starts playing. Unfortunately, again, the track may not actually be fully downloaded to the app’s satisfaction so the enhanced audio features won’t work with it until such time that the app believes it’s fully on board the device.
