Hi there, I am currently trying out the new FMOD Studio version, the changes made in the Studio software and in terms of performance are amazing! However I did find a problem concerning read-only parameters - they seem to fail being controllable by automation and modulation. On my main project we use a lot of read-only parameters which use an AHDSR modulator to drive the parameter value when the event starts/stops, as well as read-only parameters that are driven by sidechains. On the latest FMOD Studio version 2.01.00 however they do not behave in the expected way anymore and their read-only flag has to be removed for them to operate in the usual manner again. I hope this problem can be fixed in the next release of 2.01, for now removing the read-only flag seems to be a working solution. Thanks for an amazing release, loving the new features! ---

Thanks for the bug report! I’ve added this issue to our bug tracker, and it will be fixed in an upcoming version of FMOD Studio.
