Limited, but potentially useful
As somebody else stated, this app does what it says... To sum up its abilities and limitations:
It allows you to loop an audio file and push/drag the timing to match the timing of another sound source. It also gives you tempo adjustment so you van match the tempo of another sound source.
These are all the basic features which are required to use this as a Dj tool, except that the tempo adjustment has a very limited range only being able to be adjusted from about 110 bpm to 140 bpm.
Give a wider bpm range and the ability to play mp3s and this could actually be used as a virtual turntable. Then add some touch screen scratchig and then youd have a serious Dj tool.
Keep working diddy, its coming along!
