I am a newby, so apologies if the question is trivial. I think that PTE is superior to other similar software, especially in what concerns the stability of the program and the quality and smoothness of the transitions. But there is one feature that other programs have and that I am missing in PTE. That is the possibility of assigning individual duration times to both slides and transitions, and, then, when synchronizing to music, these times be proportionally changed according to the duration of the music. This can be done in ProShow, for instance, even selecting parts of the show and synchronizing them with parts of the music band (song tracks, for example). I know that this can be done with utilities such as SyP and PTE Adjustor (although not very conveniently, in my opinion), but... is there any project to make it possible directly from PTE? Thanks for your responses, Xabier.
