this problem only occurs when -ffast-math is used

This should now be fixed.

Please perform a clean ./configure and build after updating your source tree to 
ensure the new build settings take effect.

The -ffast-math compiler option (which was enabled by default for amsynth) was 
completely breaking the parameter updating mechanism. I have now disabled this 
optimisation as it is clearly harmful.
