Button to execute shell script on Push 3SA ?

[mattjakob]

I wrote this python script and can run it successfully on Push3 SA via ssh but I was wondering if theres an easier way to do this… either create a button in M4L that triggers the shell script (tried max shell object but doesnt seem to work on Push) or maybe if there’s an easier way to do with a M4L device ?
(basically Id like to experiment with creating live visuals on my laptop using midi output from Push3 SA over Wifi)

Thanks
