Mephisto
a Just-in-Time FAUST compiler embedded in an LV2 plugin
Write LV2 audio/cv instruments/filters directly in your host in FAUST DSP language without any need to restart/reload host or plugin upon code changes.
Use it for one-off instruments/filters, prototyping, experimenting or glueing stuff together.
Note: This will need a fairly recent libFAUST and/or bleeding edge GNU/Linux distribution.
