[PD] easy effects?

hi everyone,

I'm back again! :)

I'm working through the various pd resources and learning how to do various things and having a lot of fun. I've built the step sequencer from the FLOSS manual, and want to apply some effects to the sound (such as delay, distortion, etc.). I've found some resources on the 'net on how to build such effects from scratch, but it seems like it is reinventing the wheel when I have access to so many great effects on my system already (ladspa, dssi). I've attempted to use the plugin~ object, but when I try to right-click on the object to get help, pd crashes. are there objects in pd-extended that allow you to use ladspa or dssi effects?

I'm running linux with the latest pd-extended nightly build.

thanks all!
