Probably PG Music wanted to create a showcase for new styles and real tracks with these songs?
I use these songs to test harmonies and effects in Atmos mixes (a new territory for me in Cubase 12 Pro). They are perfect for that.
But If the vocals are of a different quality than the rest of the tracks, it becomes harder for me to learn. I would be happy if pg distributed the missing wav files.
For Atmos mixes I need to convert all wav files from 16bit 44khz to 24bit 48khz. A wma (compressed!) as a starting point means a clearly audible deterioration.
I can still fall back on the 2022 artists performance sets. (Because of these missing wav files I haven't heard all the songs yet. It's just not enjoyable)

I was referring to changing part of the melody (a few bars) within the song.

The "Change Melodist" feature (part of the Melodist Jukebox) works for me.
The error is, the Melodist Jukebox does not generate a new song after the 2nd run.
When I reopen the Melodist, I can see that a new Melodist has been selected in the Melodist window. However, song names, chords and a melody are only generated in the first pass.
After the first pass song ends, the Melodist Jukebox stops.

I hope this can help. I love the Melodist unfortunately it is very underrated.
This forum sadly doesn't offer many information about the melodist.

Please let me know where can I get the missing uncompressed wav files.
