Since this morning, crossfade~ from the RTC library is working the other way around: 0 brings the right side and 127 the left side, when it is supposed to do the opposite. 

Just opening the help file in Max 7.3.4 shows this behavior.

The strange thing is that crossfade~ is an abstraction using [expr sin($f1*1.5707963/127)] on the left side and [expr sin((127-$f1)*1.5707963/127)] on the right side. 

I am not very good in maths but I doubt someone changed the sine function overnight, so what is going on??

I have been using using crossfade~ for almost 10 years and have this object all over the place in my patches. I have started to "paste replace" with M4L.bal1~ but this is a pain.

Hello,

crossfade~-from-rtc-is-inverted

For more than 10 years it used to open the left side when a 0 is sent, and the right side when 127 is sent. What happened?? Did someone change maths? Am I in the black lodge?

hello, I haven't figured this one yet
The basic patch is the following.

the thing which has changed since yesterday is obviously that you installed a new abstraction called "crossfade~"

Haha, thanks! yes that would be the most logical explanation

I guess I've updated the RTC library at some point and Karlheinz Essl changed this object...

crossfade~ from RTC is inverted??
