[LAD] LV2 mono instruments recommended?

Hi! I'm currently implementing a LV2 plugin for SpectMorph, and so far I only defined one audio port in the ttl file/source, as the output of the morphing algorithm is just mono. I have tested with Ardour and Qtractor. Ardour does what I'd expect: it plays my instrument output on both channels. Qtractor however just plays my mono data on one channel, the other is silent. Which is not what I want. So I am considering making my LV2 instrument always stereo, and just copy the output buffer from left to right - this is cheap, and probably not much more expensive than what the host would need to do anyway. Does this sound like the reasonable way to go? Cu... Stefan -- Stefan Westerfeld, http://space.twc.de/~stefan
