I think this is a bug in plugmultiparam. In a pluggo with a multislider
connected to plugmultiparam, loaded in Max with vst~, no parameter index
and value are output from the 4th outlet of vst~, when multislider is
changed with the mouse inside the plug, or when programs are changed.
Only when option click -> Undo Last Change, Randomize All, Evolve All
and Copy All From Program is used inside the plug output is OK.
I have been testing this issue on MaxMSP 4.5.7/Pluggo 3.5.4, PPC G4 and
MaxMSP 4.6.2/Pluggo 3.6.1, PPC G3, both running Mac OS 10.4.8
I'm transmitting the data from the vst~ outlet to other machines using
udpsend/udpreceive, and it would be really usefull to have
plugmultiparam working for this purpose.
The following patches should show the bevaviuor.
build a pluggo from this:
