Lemme start by saying that I know that this is VERY difficult to do because of how songs are produced. But it being 2015, and with technology having come this far, I'm sure there is a way that this can be done.

I love creating remixes on the fly by mixing different acapellas and instrumentals during my sets. But in order to do this effectively, I have to have the acapellas and instrumentals that I plan to use beforehand and at an easily accessible folder so that I can go back and forth with them. Other Djs who do this know that this takes lots of time, especially finding high quality acapellas and instrumentals.

It would be sooo awesome if there was an effect that we could use that cuts out (on the fly) the instrumental and leaves only the acapella of the track that's playing, to which we can throw another beat underneath and create a nice mix. Or vice versa, use such an effect to remove the vocals of the track that's playing thus leaving the instrumental playing to which we can throw an acapella ontop of that instrumental on the fly.

There are some effects out there that exist that try to do this, but tey sound so shitty that it is unusable. Also, cutting out the bass or meddling with the mids and highs doesn't create a nice clean acapella-instrumental blend that you would get by having the clean acapella and a good sounding instrumental.

In my opinion, such an effect would infuse so much creativity and encourage more live performance of music as opposed to relying too much on pre-produced mashups that tend to leave the Dj doing almost nothing live.

I'm sure there's a way this could be possible in the near future; we need to take our performances as DJs to the next level and bring the live performance of music back!!

Thoughts?
