I Use It Frequently


Some of the criticisms of this app are fair: it’d be nice if it’s user interaction was more like other Mac apps — for example, cutting a track like you do with iMovie of FCP. That having been said, I use this app all the time to get tracks into the same tempo, even if I’m not making a mashup within this app. (For example, I’ll get multiple tracks into the same tempo using this app, then import the tracks into FCP.) I think this app also does a really nice job of finding songs that are haromonically similar. As others have pointed out, with just a litlte more work this app would be 5 stars.

Hey Jim, thanks for the review- I really appreciate you taking the time to share your ideas!I can definitely see how these features would be useful. I’ve just added to our Wishlist and we will keep in mind for future development plans for sure :)

Make these improvements:


A few small but key improvements would make this one of the best DJ apps out there.

There needs to be more quick keys to make this a seamless and popular app. First include a play from start quick key like Enter or backslash. Copy/Pasting is laggy. Make looping an option. Integrate itunes into the applicaiton so the consumer doesn’t have to import all of their music. DJay manages to do that. Add effects like fade, echo, reverb, flanger, etc.

This has a ton of potential. If the creators make a few changes I imagine they would make a killing. Until then, this is very average.

Thank you for all your suggestions. We will definitely take them into consideration when we start working on a new update :)

No Detail!


This app has a great appearance and is user friendly. That being said, it is focused more on the appearance then the music making.

This application is worth maybe .99 cents. It gets the basic job completed, but when you pay 30 dollars for a mashup music application you expect to be able to cut the soundtrack at specific, detailed places. This application will not let you do that. Example: you are able to zoom in very close up, which is a huge plus! However, if you decide to trim a specific part of the song in the visualized stream, it cannot cut at that exact point. It will vear to the left or right depending on where the closest beat/rhythm visual point is.

Do not purchase this application if you are looking for more detail oriented software. This should not be for sale for 30 dollars, huge rip off. Add more detail, (such as being able to cut the song at certain points) and this application would be gold. Absolute gold.

Please update the application!
