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.

@ddw_music Thank you so much. That helped immensely and was much easier than I thought once I knew where GEM installed.

It was as simple as:
$ sudo apt install gem
// Then just to see what came up:
$ apt show gem
// Then to see that gem installed where you said it would:
$ dpkg -L gem
// and /usr/lib/pd/extra showed. I hope it does not cause any problems there.

Sorry about the hacked together reply with odd formatting. I do not know how to add the blackbackground formatting yet. I imagine there is a sticky somewhere about that.

From there I opened Pd, went to Preferences > Edit Preferences > Path > New > went to the root and selected /lib/pd/extra/Gem.
Then went to the Startup tab > New > typed in Gem + Enter > OK.
Then I closed and opened Pd and it showed GEM loaded. I opened a basic example from the Browser and it ran. I see now what you meant by [declare -lib Gem]. I am very new to Pd and have also been learning SuperCollider. A lot of the things get forgotten until I get into the relative platform environment. In that example, [declare -lib Gem] was there. It looks just like it does on the Mac.

@willblackhurst if you get to work, can you please provide the commands you used to install it? It would be greatly appreciated. I have tried several things to install it.

In my op, I provide what I used to install it but I think that was just for Ruby. I could not find the library anywhere on my Raspberry Pi and as I searched for the answer, I think what I did was install gem for Ruby. I do not have Ruby installed so I could not even get that to run and I am not looking to figure that out to even see if that would have any benefit for me. Not at this point anyway. In the end, I uninstalled gem.

Maybe the problem is with the current Raspberry Pi OS, Trixie.

When I type gem in the deken - Find Extenrals window, search field and click Search, I get the following:

Searching for "gem"...
Searching on http://deken.puredata.info/search...
Searching on http://deken.puredata.info/search returned 21 results
"gem": Found 0 usable packages (of 20 packages in total).
It appears that there are no matching packages for your architecture.

Maybe it just will not work with the Raspberry Pi at this time.

Hi. I am trying to install the GEM external for Pure Data on my Raspberry Pi. I have always found installing source code troubling as I do not know nearly enough about programming to work with all the options during the install.

I did find out that you can install GEM with the command line so I did that:
sudo apt install gem

I cannot find where it installed to and typing $ gem
gives me nothing but $ sudo apt install gem
gives me:
gem is already the newest version (1:0.94-8+b5).
Summary:
Upgrading: 0, Installing: 0, Removing: 0, Not Upgrading: 1

I can point Pure Data to a normally installed external when I know where it is. How do I find GEM so I can point Pd to it?

There are some more patches up in the "Working-Through-Pure-Data-Programming-Fundamentals-Vol-1" repository on GitHub: https://github.com/playinmyblues/Working-Through-Pure-Data-Programming-Fundamentals-Vol-1/tree/main

Hi. I have created a new repository that I consider patches that are more of my own exploration of Pure Data. I am currently working through Maurizio Di Berardino's book that I have mentioned before, which is pretty good. But these patches are a lot of my own explorations of Pd and figuring out some stuff on my own while I do that. The is a fair amount of jumping ahead of the book but that is fun too. I also started using my Raspberry Pi Zero W again, figuring out things on that in preparation of the idea of turning my cheap Barracuda bass into a synth bass.

Here's the repository if you are interested:
