By a massive coincidence, I first sat down to check this app out after a practice session. I was playing along with a recording and wishing it was just a tiny bit slower.
Now I’ve got the solution for the next time I practice – Capo, an app designed by SuperMegaUltraGroovy. Because that’s exactly what it does; allows you to take songs from your iTunes library and slow them down without changing the pitch so you can play along.
Capo is a fantastic tool, and very simple to use. Open it up and you’ll find a blank menu. Tap the “add” button and select any tune from your iPod. Once it’s on the menu, select it and you’ll see the waveform display, along with options to listen to it at regular speed, 3/4, 1/2 or 1/4.
And you can further customize the speed easily; just touch the fraction and slide right over left. A percentage marker will appear above, you can slow that tune down to exactly 63% if that’s your magic number. Tap play and listen to the song, slower but in the same key.
If you do want to change the key, tap “Pitch” on the bottom left corner. You can listen to the song and slide the slider left or right to go from Andre the Giant to Alvin the Chipmunk as needed.
Capo has a few other helpful features as well. You can set markers both while the song is playing and when it isn’t by tapping the marker icon on the left, then tapping it again to delete it. There are right and left arrows to help you navigate quickly between markers. And there’s also a loop feature – a great tool for practicing musicians. Find the start of a particularly tough section of the song and tap “A,” then tap “B” at the end of the section. Tap the loop button and that section will play on repeat (and at whatever speed you set) while you practice along and work it out.
This app comes with a rather hefty price tag, but rest assured it works, and for me, having the ability to practice this way with my iPhone rather than my laptop is a definite bonus. I’d highly recommend checking this one out to improve your practice sessions.
Capo [iTunes Link] is compatible with iPhone, iPod touch, and iPad. Requires iOS 4.0 or later. A small expedite fee was paid by the developer to speed up the publication of this review.
