[PD] how to prevent midi endless loops?

[wolfgang schwarzenbrunner]

hi

maybe a quiet simple question.... i need to use a midiinterface (doepfer 
pocket dial) to control slidervalues in pd (windows -- xp 0.37). the 
problem is that i also want to change the values using the sliders in the 
patch and having this data being sent back to the controller so that there 
are no jumps in value when switching from screen to hardware controller and 
back...

finally i built up a very simple t b f b and spigot combination to prevent 
stackoverflows within pd. this works pretty fine as long as i don`t use 
mididata to control the sliders... attached is a little patch that should 
explain...

any help needed...
