if I ignore your questions, it is probably because the answer is below.
note to queries on deleted content,
most my most viewed uploads in a playlist called all my crap, not deleted as are not considered by me stuff I wish to be known for,
so you can still view it if wished.
I am just a hobby animation software user using ready made content, just having fun on my computer and sharing.
Most of my videos use melody assistant by myriad for the virtual singing and music composition or played on my Roland Gaia synth to my Boss Dr Rhythm , other videos are audioswapped using YouTube's option to do so, the former can be downloaded if you wish but do not use my work for commercial purposes unless CC. Embedding, sharing ok.
my favourite software is Carrara by DAZ 3D.
I also use Poser7 from Smithmicro/content paradise and iClone from Reallusion all cost money but if after using for example the free DAZ studio also available from DAZ 3D you like doing this stuff, are worth buying
