4.5 years later, I got it. All dependencies explained in this other thread: https://chipmusic.org/forums/post/260091/#p260091

But to fix the above error:

sudo apt-get install libasound2-plugins:i386

bad advice..

I got curious and tried the ghetto build that didn't go so well:

[CONFIG] Got config path=/home/todd/music/lgpt_DEB/bin/config.xml

Segmentation fault

Oho! Good solution!

Ha figured it out! I remembered I had multiarch-support installed. So remembering that with multiarch -support installed to install a 32 bit version of a library/program/etc. you do sudo apt-get install packagename:i386 . So with that in mind I did

sudo apt-get install libjack0:i386

and tried to run piggy after and it works Set the window to floating for my i3 wm and everything's good!

And reaper.

Haha yeah I wasted a lot of Mark's time before mentioning it myself.  I've switched back to windows purely for proper piggin.

That explains it!

Are you on a 64bit system? Cause that sounds exactly like the issues I was having. Currently piggy can't run on 64bit linux.

Not the linux one, I found out I can however run the windows version through wine. Not sure if it's running properly in its entirety, the misc. samples just sound like short static click noises. All the other samples run fine though.

Does piggy run at all?

Sorry I haven't tried this in a while. I installed libjack0 as it asked for libjack.so.0 and it still wouldn't work so I linked it to piggy's folder in its bin folder and it still says it can't open the shared object file.

yeah. since it can work with jack, it needs the library. But if the jack server isn't started, it will use alsa.

You can install it but not use it...?

To run lgpt, you need the jack libraries to be installed. But it doesn't mean you have to use jack as output.
