I recently discovered Liftor and must say that i'm really impressed why nobody else had the idea for a tool like this before.
Liftor does an excellent job in providing pitchtransitions and uplifters. you have 50 waveforms to choose from and that alone is worth more than the asking price IMHO.
And for the price it's a steel, you can't go wrong. I am into pop and dance music and haven't touched my arsenal of uplifter loops for days now. Anyone who has kontakt and is into modern music production should definately check it out. This is an unbelievable timesaver.
I only wish there would be more control about the oscillator, to even add more variations. but for now i am more than happy. the randomization does amazing things too.
