Another weird experiment, mixing synthwave with a rap sample and adding some light vaporwave treatment. Finally upgraded my Arturia V Collection to get the vocoder, DX7, Juno, CMI etc. and tested everything. So good again. Arturia never disappoints.
As weird and bad the song is, a useful takeaway for me is that using Eventide harmonizer and microtuning plugins makes it much easier to place a vocal in a song compared to all other methods I tried before.
