Another bug to the list.
After the update, I have found my TI keyboard (in non USB mode), the amp/filter knob controllers not affecting the envelope/patch.
I tried over 15 different patches and no change. The value parameters show change, but no tone change.
You could have decay, sustain and release on 127 and would remain a short tone.
I will try VC mode tomorrow, but see if this is happening to yours.
Try a short stab patch to easily diagnose
I also had problem with any parameter changes on all other knobs. The value wouldn't note any change, until you turned it to it's shown value, then you could make a value change. This has also carried over to os5.
