There are 4 voices ... but only to save people having to do the changes themselves on the basic bass and soprano voice. Feel free to use, change or store them.
You can get an idea of them from the attached mp3s. The main change needed for these voices was an increase in vibrato.( though I couldn't bring myself to use the deep, slow vibrato of some singers ) For the faster voices the vibrato had to start almost straight away. Slower voices (with less attack) seemed better with a delayed vibrato. And even after that, the 'demos' of Mozart attached seemed to need vibrato 'effects' added ( less and more) at various places.
The new Davio Bass voice has only a slight tone change from the David bass voice previously uploaded, but the soprano voice was a challenge.
When I listened to real sopranos I was amazed by the way some articulated the lyrics. And their vowels were often very strong, even on high notes. This doesn't seem to be easy to match in HA voices! I applied the equalizer in HA's 'advanced editing' to make aahs more 'aahish'. and 'eee' less squeaky... and so on. And the the consonants were sometimes adjusted to make then more or less audible.
My feeling is that the voice fragments change balance as the voice rises and falls in pitch, so it's best to test the changes you make on a staff with a short tune in the voice range you are aiming for ( rather than the mid note of HA test fragments). You can then play and stop it from the fragment editor itself.
And there's a major problem with this operatic stuff. If you want to get the most ' life' into the voice you will probably need to apply parameter curves ( volume, treble and even bass if needed) ... varying almost all the the time. ( And the words did get some strange spellings to change the sound in places.)
This means you have to be a bit inspired by the piece you are doing or you will never keep going through all the trial and mistakes!
And the voices seem to go well with some choir styles. I used HA's aah2 choir with its velocity sensitivity increased in each part. And then added 2 different real singers to each part, all panned to give a sense of space.
Interesting thing in the middle Handel extract. The volume rising /falling <> effect was applied and seemed to be a good way to make the fast notes sound like some choirs sing them.
Hope that's of interest.
Addition ... before I forget .. the 'Davidia' voice uploaded earlier was discovered to have a fragment ( CH) that had been set to almost zero volume at some point. A corrected version is now in the previous '5morevoices 'zip file.
