This fork was made to re-add purposefully removed features by Calf developers, which includes LADSPA, DSSI and LV2 External-UI support.
Additionally, LRDF typos were corrected and all DSSI GUIs work now.

The new source code is available here.


This is a fork of dssi-vst, initially based on "k_amlie"'s code updates (to make it more RT friendly), with additional fixes from falkTX which includes:

  • Enabled compiler optimizations where possible (ie, -O2 -ffast-math etc)
