I need a DJ App created similar to djay.
The app needs to be able to load music from current library. One song gets loaded into two players. User will be able to set delay, one player is milliseconds slower than other. User will be able to manually 'scratch' on turntable then hit sync to restore the players with the delay. There will need to be a crossfader to switch from player to player. Also will need a way to record remixes and post save new song as audio file.
I prefer to work with a development firm that has experience with multimedia apps in IOS. Please show past multimedia apps that you've developed.
