If not already there, put path /usr/lib/lv2 in:
MusE>Global Settings>Plugin Paths>Lv2
And restart MusE. If path's already there, force a plugin rescan (option in same dialog window).
Still can't find the plugin? Maybe it's misrepresented* in the "add synth track" dialog as an effect, so be sure to look under "all" categories.
*due to ubuntu lv2 package possibly being incomplete, if you have ubuntu. Remedy by installing lv2-dev.
