For digital DJs, the computer often still trumps the iPad. You get (much) more storage, more flexible use of hardware, more features. But wouldn’t it be nice to use a tablet for X/Y control of effects?

TKFX does that, and nothing else – but it does it damned well. It works on Android and iOS alike, and it’s dead-simple – and powerful. Traktor’s effects are one of the best features of the platform; this finally gives you intuitive control over them.

Hold function
BPM sync
Up to four effect units
Four memory banks
Use in single or group mode

You can also pre-program the effects you want to use – 4 banks x 4 each, for a total of 16.

Free to buy; add additional modules as in-app purchases. It’s pretty capable as-is for some users; US$0.99 each unlocks specific unlimited features or US$5.94 opens up everything, so you can be flexible with your needs.
