Example Pipeline:

gst-launch-1.0 -v filesrc location=/usr/share/sounds/login.wav ! wavparse ! audioconvert ! plugin-org-uk-swh-plugins-djFlanger ! audioconvert ! autoaudiosink

Requires calf <http://calf.sourceforge.net/>
GST_DEBUG="*:2,lv2:5"
gst-launch-1.0 calf-sourceforge-net-plugins-Monosynth event-in="C-3" ! autoaudiosink
gst-launch-1.0 calf-sourceforge-net-plugins-Monosynth event-in="C-3" name=ms ! autoaudiosink ms. ! fakesink
gst-launch-1.0 calf-sourceforge-net-plugins-Organ event-in="C-3" name=s ! interleave name=i ! autoaudiosink s. ! i.
TODO
* support http://lv2plug.in/ns/lv2core/#CVPort
- these ports need a buffer with the property value
- we should sync, then fill the buffer and connect the port
* support presets
for pl in $(lv2ls); do if test "$(lv2info "$pl" | grep -A1 "Presets:" | tail -n1)" != ""; then echo "$pl"; fi; done
* support more host features
GST_DEBUG="lv2:4" GST_DEBUG_FILE=/tmp/gst.log gst-inspect lv2
grep -o "needs host feature: .*$" /tmp/gst.log | sort | uniq -c | sort -n
* example sources:
