I don't see too many projects using vocals but I have started to incorporate them into my work. They are challenging to deal with so here are some of the lessons I have learned. I don't profess to be an expert by an means, so take it all in stride. Many of the tutorials I found used other DAWs and I tried to replicate the teachings here.

Notes:

1) I used stock plugins where possible. There is no AutoTune in LMMS, so I used "Auburn Sounds Grallion 2"

2) There are hardly any vocals in stock LMMS, so I had to get creative using a couple I found.

Here is the clip, which is broken into two main sections (Vocal Manipulation and Making Space / Mixing).



EDIT: I realize in the project notes I didn't specify that the Vocoder Modulator and Carrier need to be panned opposite. Please note that when opening.

EDIT2: Here is the song I made for my kids where I applied some of the techniques. I wanted to put all the lessons into one file for future reference.
