Hi Terence,
djay 4 for Mac does have waveforms but it’s not as “advanced” as the one in djay 2 for iOS.
By the way, djay for Mac will greatly benefit from the development of djay 2 for iOS.
NO, sadly, it does not…although many people are holding out hope that they will release a new version for Mac that includes this. No official word from Algoriddim though.
