Thank you for your insights anyways - I will continue to look down this path!

it just occurred to me that your project would be running on a phone or tablet is the pd file on a PC?

Yes, MobMuPlat runs on Android and iOS.

Interesting approach to make and fill a txt file with the folder contents (and you're right, it's the soundfiles I want ). I would need a command that works both on android and ios and for it to be triggered from the pd patch then.

Hi, I'm trying to develop something with MobMuPlat, which uses libpd. It's hard to know what objects that can be used or not because it's not listed anywhere I can see but from trial and error I think it's somewhat close to vanilla 0.48. So no [file glob] or [pdcontrol], or externals...

Anyone have an idea of how to get the contents of a folder (the folder of the pd patch) as a list in vanilla 0.48?
