Another way to make a YTPMV (YouTube Poop Music Video)

I was thinking if it was possible if you can make a YTPMV (YouTube Poop Music Video) (the way you do it with Sony Vegas) with Audacity, and after past experiences of using Audacity,
I came up with the conclusion that you can’t.
Here is one reason why:

-Audacity can’t loop play AND do real-time editing (at the same time).

I might be wrong here that making music out of sound clips with Audacity is impossible,
but if you’re not one of those people who know which pitch to shift the audio to after
just listening to it multiple times, then that just proves that it’s hard without Sony Vegas
(which costs a lot more than using Audacity).

Unless i’m right, feel free to post some suggestions.

Those are MIDI trackers.
Also the Free Video editors are like slideshow creators.

They are lists of free software which could be used to make that type of music video.
Also see the sequencers on this list … Music sequencer - Wikipedia

I’ll just buy Sony Vegas Pro.
