I have been trying to get the Portamento glideTime control to work at the group level. If I use the global binding:
<binding type="amp" level="instrument" position="0" parameter="GLIDE_TIME"/>
then it works, but if I use 'group' binding:
<binding type="amp" level="group" position="0" parameter="GLIDE_TIME"/>
then the portamento/glide time is not controlled...
(I have tried putting glideMode in <groups> and in <group> and this does not affect the result...)
I'm obviously doing something wrong - what is it?
