[PD] MobMuPlat for Ipad and expr~ woes

[Patrick Pagano]

I will go through and share the expr~ equations and hopefully this 
awesome bunch of pd masters can help with some suggestions.
What i did was open the patch i had made several years ago and seeing no 
error in the MobplatPd window i assumed i was okay, which of course is 
my downfall: assumption. Then i got excited making the interface and was 
crestfallen when i saw the message in the pd console on the ipad.
