ladspa~ for pure-data

This is a fork of the historical plugin~ ( of pure-data (found in pd-extended distribution), but with bugfixes and with VST support completely removed.

I had problems running plugin~ , mainly due to lack of error checking causing annoying segfaults and making this object nearly unusable for me. I decided to patch the code to make it run smoothly.

The library seems to never had support for VST plugins. And as i found the name confusing, i renamed it to match its exact behaviour.


So far, here are the changes against former plugin~ object:

  • fixed segfaults by adding error-checking
  • updated the doc
  • added a optionnal -DDEBUG flag to see debug messages
  • removed useless post() messages from retail version
  • removed the buggy "plug" method
  • added boundaries checking for LADSPA control parameters
  • prefixed all methods with "ladspa_tilde_" to avoid namespace clash
  • completely removed support for VST. For VST plugins in pure-data, see the vst~ object.


You can download the linux binary here: ladspa~.pd_linux
