I made a simple instrument with a parabol osci.
When a Native Instrument FM7 was loaded before or is loaded paralell in Energy XT the lower part of the curve turns to saw. Seems the FM7 writes in the SM area. Even reloading the Tester instrument does not change the behavior, I have to quit XT.

Is there a demo version of FM7 I can try this with do you know? Does it happen with any other non-SM plugins?

I think there is a FM8 at NI but have not tried with this. As I do not make any music currently, shame on me, I cannot say anything about other plugins. No problem with SE plugins. I can reproduce this too in VST-Host and also when changing from int to float abs (ABSMASK=3.4e38|0.999999|0.1;)

I investigated this a bit further: It`s the rounder code (addps xmm0,F8P38861; subps xmm0,F8P38861; ) that stops working. I think this like overdriving to cut out the fractional part. Conclusion: There must be some cpu-flag for exeption handling that is set by the FM7 and not reset. For sure a FM7 bug but this flag should be initialised on loading SM too.
Hope this helps

Sorry, I was wrong. 😮 It is the "int abs" or the "and", cannot measure that, so I stop here. No big problem anyway.
