The Next.... NEXT Generation Piapro:
Completely stupid information, but I was looking at Piapro on YouTube and saw that when Piapro Studio came out (2013), they said it was the "Next Generation" vocal editor.
Yesterday, they teased the new engine also as being "NEXT Generation".
So, this is the next NEXT generation version of Piapro.
Why other Vocaloids (including older Cryptonloids) are not compatible with the new engine:
There goes all my excitement about the announcement. It seems weird to me that they'd go through all the effort of making a new engine but then not allow other companies to develop VBs for it, since I feel like that would make it way more successful. I like the Crypton gang a lot, but most of my fav VBs are from other companies and it's sad to see that they won't be able to jump ship like the Crypton VBs are now going to be able to. Looks like I'll be using Vocaloid4 forever :/
They had to manually edit all of the Cryptonloid voicebanks by shortening the clip length and changing the pronunciation to be clearer and less muffled.
They had to do this in order for the new voices to work with Cherry Pie (Cherry Pie is vocal analysis synthesis, it takes the input speech and breaks it down to the smallest unit of speech--phonemes). So if they have a specific unit of measurement (also used by the HMM math equations for the engine itself) for how long the phonemes have to be and had to go through the manual labor or editing every phoneme for every voice bank, it seems like any old Vocaloid (even old Cryptonloids) are incompatible with the new engine.
Add to this issue the fact that Cherry Pie is used for real-time voice conversion built from specific patterns they taught their deep neural network, if the phonemes were too long and not fitting the standard required for clear pronunciation, it seems like the results would sound horrible.
I "enhanced" the teaser image for the upcoming Piapro Standalone:
The most interesting thing I noticed about this teaser is that the old parameter names seem to have been changed and they are split into multiple categories. Oh, and the glue tool is fixed (it's the opposite of the tool to cut notes in two).
