@mosef123 You're also missing edge~, so you probably need the cyclone library. There are a number of tutorials that tell you how to make your own oscilloscope. Here's one:

The dashed box around speedlim means that you don't have that object. You should have gotten a message in red on the pd console to indicate that problem. There are several external libraries that include speedlim. You need to decide which one to use. Where did you get the oscilloscope subpatch? It would be a good idea to use the same speedlim that they used.

@whale-av Thanks! This looks promising. I'll give it a try.

Edit: That worked thanks!

@Balwyn Your [file cwd] example looks like exactly what I need, but it didn't work with read. Your example with the close, open message works on my system, but when I tried to use the read message to read the file, I got a "can't read" message. Any ideas on how I can make this work? Thanks!

Edit: I opened issue #2888 on github for the problem that [file cwd] doesn't work with read.

Thank you, @unclewayback and @whale-av for your replies, but that doesn't solve my problem. The example I gave was a simplified version of what I'm doing. I have 129 files in each directory. The file names are the same in all the directories. (There are three directories now, but there will soon be more.) I have a selectable list of file names and I want to be able to open whatever file was selected in the currently selected directory. I'm currently using $1 in the read message to pass in the selected file name, so I can't use it for the directory name. Is there a way to put two variables in the read message?

I have hundreds of data files in different subdirectories that I read into wavetables. I want to dynamically change the directory that the files are read from. I tried sending a dir message to pdcontrol, which appeared to work, but pd does not find the files in the subdirectory. How can I dynamically change the directory that files are read from?

file_open.pd

This is awesome!

Did you click Graph-On-Parent? That would make a red rectangle that can't be deleted except by unclicking Graph-On-Parent. To get rid of the rectangle, right click on the patch, select Properties, and unclick Graph-On-Parent, unless you want to use the patch as an abstraction.

I've made some minor improvements to the code and the knobs. I've also designed slider knobs for the MIDIMix. You can download the new code and knobs using the links in the previous post.

@jamcultur it is good to see you found your source of the error. Does that tell you why? And I am curious how you found it.

Seeing the code with the error doesn't tell me why the error occurred. I found the code using the findstr command on Windows (similar to grep on Linux). I searched for the code referenced in the error message that was issued to the Pd console. Do you not get the divide by zero messages on your Pd console?
