LV2 is an emerging standard for plugins and instruments on Linux. It’d be nice to have support for it in Renoise.
I would also like to support this. I previously suggested it in the beta suggestions forum. If a developer of Renoise got in contact with somebody from Ardour or the guy from linuxdsp (Who makes some great commercial lv2 plugins) I’m sure they would be happy to help implement the standard with you.
