You can remove the vocal of a song, make a song faster or slower, and change the key of a song with this app!

The app is good for performers who cannot find the right music for their key, want a faster or slower version of the music, or cannot find the music of a song with no vocals.

And for others, it is just HILARIOUS to hear your favorite song in a different tempo or key!

Two simple steps in the app:
1. Select a song from your iTunes library
2. After the song is processed, you can then turn on and off vocals with the switch, change the speed and the pitch of the song with the sliders.

ZTX LE Time Stretch/Pitch Shift technology licensed from Zynaptiq GmbH, Zynaptiq GmbH

This is a free version of Music Factory - Change key, change tempo and remove vocal.

Bought full version and it still cuts off

I love the function of the App when it works. But it offered to buy full version, I did and was charged $2.99 and it still won’t stop cutting off at 30 seconds telling me to buy full version. I tried deleting and re-downloading and now it doesn’t recognize purchase at all. However, purchase was completed and shows on my bank account. Sadly, that is dishonest business if it’s not corrected or refunded.

It's awesome!

Well you bad reviewers obviously don't realize that they took out the vocal track. Most singers use harmony and that's why you still hear the voice. So that works nicely! Also, I like how you can speed up or slow down the song while you can change the pitch! Although, I wish that you guys could've made just one big app with everything in it rather than one app just for pitch and the other app with everything. Losin money 😕. But overall a really good app I would recommend it! 👍🏼

I think it's great!

Alright, I'll take one star off because when I load a song, I always need to press the home button and then come back to the app. Also, it's true that removing the vocal isn't complete. But to be honest, having this app at that price is fairly reasonable to me. Everything else is working very well, and I love it!
