@jamcultur I am wondering if there is a quick way to search through the files using a text based search. I know you can open Pd files as text files and there is a syntax to them. I think you can edit them as well and produce working Pd patches.

So here are the results from a search on the MacOS cli:

I am going to refine the search method to include the relationship/equation from the error message to see what happens.

@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.

@jamcultur have you edited the original files in any way? In the cases where I have tried [mimba], it has worked, as far as the interface goes. I have a hard time doing anything in Windows with it as I can only play one note and sometimes, not even that before I get static crackling type sounds.

Do you have access to another computer where you can try using Pd? Or an iPad where you can install Plugdata? I wonder if it might be your computer if Pd might be conflicting with something. I am taking guesses, really, as I do not know a whole lot about Pd beyond what I have learned from the book I am reading, and I am not even a third of the way through that.

If you can try it on another Windows computer and it works, it might be something on your computer causing the problem. There are other methods of using your computer with another operating system, such as using a Linux Live CD, but you have to be very careful when using that to not overwrite your current OS by mistake.

@playinmyblues btw, Pd does not work very well on my PC but I could get the patch up looking like it was fine. I just could only play one note at a time and even then it was crackling at time. My PC is not great for this type of thing.

@jamcultur looking at your sreenshot, I do not know. Is that what you get when you open main-mimba.pd?

@jamcultur I was really commenting about hansr's question about his patch and how it worked on his computer. I saw shortly after that the op was from three years ago. But I am going to have a look at my old Windows PC to see if I have any problems with Pd.

I gave it a brief go in Bitwig using Plugdata. It seemed to play acceptably well with 3 notes, Static crackling with 4 notes, even with increasing the sample block size to 512. But again, it seemed to run fine in Pd standalone.

@hansr No problems mashing the keys with a MacBook Pro, M3 Pro, 32GB RAM. I like the instrument, btw. I am just a noob here. Still working my way through a book on Pd but I am really enjoying it.

It has been a while since I have updated the repository but here is my latest batch. I have been doing some work but also kind of got into SuperCollider again. Too many interests but I oscillate.

And I made a new drum machine in miRack. You can check that out on Patchstorage if you are interested. Synth Drums 5.

@alexandros Thanks for the tips.
Much appreciated!
I knew about the [declare -patch Gem] use and with other externals/libraries, stuff usually that you are taking from libraries on a piece by piece basis. But I probably needed a reminder. I may have incorporated the declare without thinking about it. I am working through a book on Pd at the moment and am using my Raspberry Pi for a lot of it, seeing if I can get it to work.
