OK, at first a big thank to all those who try to solve this "mistery", it helps to feel better!

Noel, I have now tried to change the settings according to your instructions, but no change. When I go to the default synth screen, the only possibility I have is Sforzando. Scaning then for new plugins just seem to reset my DXiplugin.init to 0 (meaning it erases the settings I had previously copied from BiaB 2016)(see Photo).

As I already explained before, I have now installed BiaB 2016 on an external drive and have, from begin on, without me setting anything, Forte coyote as the default synth. So I think the problem lies by BiaB 2017, maybe in relation with the new Sforzando...
Which file should I look for and try to change? What about the folder DX- settings with files like defaultDXIsynth.tgs?
