I thought I understood giving each abstraction a unique name, [Abst 1], [Abst 2], etc. would allow differences in each abstraction to be saved, but that seems to just load the last setting saved on the abstraction into all the abstractions when they reload. Does each uniquely named abstraction have to save it's settings externally in the parent patch? Is it easier to just use Sub-patches?

I've tried what I feel like all the relevant resources from the forums, including Whale-av's ShowMeDollars.pd file, which was really helpful, yet I seem to be no further in understanding what I need to do. There was a Maelstrom savestate patch linked to the Heurleur forums, but that seems to have disappeared.

Apologies, I know this comes up a lot, but still finding it hard to crack this. Any help/tips would be greatly appreciated, I've attached the small patch I'm working on (made in Purr data if there are any problems opening it). StepSequencer.zip

After posting about UI woes (and subsequently withdrawing that post), I started looking into Purr Data.

It appears to be quite difficult to install in Ubuntu 18.04.

At https://github.com/agraef/purr-data/releases, there is no .deb for Ubuntu 18 (only for 14 and 16). pd-l2ork-2.9.0-20190416-rev.2b3f27c-x86_64.deb fails to install:

dpkg: dependency problems prevent configuration of pd-l2ork:
 pd-l2ork depends on libgsl2; however:
  Package libgsl2 is not installed.

Ubuntu 18 does not have libgsl2. It has libgsl23 -- which is installed on my system, but does not satisfy the dependency.

https://launchpad.net/~dr-graef/+archive/ubuntu/pd-l2ork.bionic is supposedly a PPA for Ubuntu 18.04. After adding it:

$ sudo apt-get install purr-data
The following packages have unmet dependencies:
 pd-l2ork : Depends: libgsl2 but it is not installable
            Recommends: ladspa-foo-plugins but it is not going to be installed
            Recommends: slv2-jack but it is not installable
 purr-data : Depends: libavifile-0.7c2 but it is not going to be installed
             Depends: libmpeg3-2 (>= 1.8.dfsg) but it is not going to be installed
             Recommends: ladspa-foo-plugins but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I haven't looked into the "not going to be installed" packages, but I already know what "not installable" means -- at least, libgsl2 doesn't exist for my Ubuntu version -- https://packages.ubuntu.com/search?keywords=libgsl2 shows "Package libgsl2 -- xenial (16.04LTS)" only.

Neither agraef nor jonwwilkes' Purr Data github repositories allow issue reports (only pull requests). So I can't ask the distributors.

I guess I could try to build it myself...? But, if the currently available release packages are not really compatible with with current Ubuntu LTS, that's not a very good situation.

Did you install it from here:

https://launchpad.net/~dr-graef/+archive/ubuntu/pd-l2ork.bionic

Regardless, you should be able to paste that data url into any browser on your Surface Pro. Let me know if you can touch in both rectangles at the same time to move around each of the circles.

Hallo
Do any of you fine people have a patch to share, to control the LEDs in response to simple touch n the Novatin Launchpad? I am able to light and dim individual pads in turn, but I'm struggling to make it polyphonic, i.e. control multiple LEDs on and off.

Thanks

@jancsika , I installed Purr data 2.5.1 via agraef PPA in Xubuntu 18.04 and Ubuntu 18.04 LTS, in all two instalations I have visual glitches with all fonts:

Can I make something to solve this little anoying issue?

Thanks a lot for your work!!

conway_2.0e3_test.zip @weightless now there is a switch for the voices. the mechanism is at the bottom of the guts and the seq subpatch. it works only for the stepsequencer like it should, because the stepsequencer changes the notes. for iterating and playing the whole grid every step, i think every square needs to be updated for the second and third voice. i dont know if that would be too inefficient. now its also possible to change the color of the squares with the second or third voice and the highlighted color with a mouse click. at the moment the click just changes to dark blue if its not dark blue already, you could also switch between the 4 different colors or something else. but perhaps its good to keep it simple.

@anibalzorrilla I don't know for Linux. Try downloading the experimental package for Ubuntu here....
https://launchpad.net/ubuntu/zesty/+package/pd-hcs
It contains sys_gui.
Otherwise apt-get get the whole extended 0.43.4 package and copy sys_gui to your Vanilla installation as above? http://puredata.info/downloads/pd-extended
Or if you don't want to install it (as it might cause conflict on your existing installation) you could try to extract it from a download here........ https://sourceforge.net/projects/pure-data/files/pd-extended/0.43.4/
David.

I just installed Ubuntustudio 15.10 Wily Werewolf 32bit on a thinkpad and I am trying to upgrade PD to extend. I am fairly new to linux but it seems like the instructions on https://puredata.info/docs/faq/debian fails.

This is the log from executing the commands. Any suggestions and help will be appreciated

Hi, vickysbooties, I know this thread is a little old, but I've managed to create a sample trigger (e.g. to play drums, etc...) based on your launchpad mappings. You can check it out here: http://code.google.com/p/purepad/

Thank You vickysbooties, i have spent the last two hours trying to program the launchpad to turn a trigger on when pressed and then turn it off again when pressed to use as a kind of sequencer. I have copied a little bit of the code you used to do that if that is ok.
