For MobMuPlat devs or users…

what is the preferred way to receive data from a multitouch GUI object? i.e. 
send out a bunch of MIDI CC messages according to 3 or 4 fingers x/y position. 
(two CC messages per finger)
i looked at the documentation and i can see the values, but i am stuck at 
extracting x and y independently for each finger “voice”. i don’t get the magic 
with [list prepend set] into [list trim], or how i can get a numeric stream 
(one value per outlet) from it.

thanks, and sorry if this question is obvious

also, is there a mechanism to save states like in pdparty? saving to a .sav 
file and recalling later?
