Plugins can provide a set of named values for a control port. Ideally only those values are set for the property. Check if all scalepoints are integers and if so generate an enum type.

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
