Well the object creates when I run the version of PD that comes with it.

About the PD distribution: PD patches for your iOS device must be made with "PD vanilla" (not Pd-extended), the basic distribution. However, in order to simulate the app on OSX (using OSC + UDP to communicate between PD and the MobMuPlat Editor), a few extra objects were needed, and so they've been included in this distribution, but they will not work if used in a patch in iOS. Also, [expr] and [expr~] do not work in the current iOS version; this will be changed in the next update.
