Found the hcs library. Thanks!

Could not find out which library contains the square~

Since support is dropped on the extended version I am using vanilla.
When I need an object which is not included I usually go to
help->find externals and search for it.

But this time I can't find the square~ object there.

Thank You, the path was right, when I put in 'beat' manually where the $1 is it worked.

The error i got was 'argument number out of range'

So let's say I got a lot of different audio files called beat.wav, beat2.wav, beat3.wav, beat4.wav ... and I want to play them randomly within a pd patch.

But instead of specifying a new path for each file I want to change one existing path dynamically. I tried something like this just to test if I can change the path.

But that gives me an error. Any advice?
