for my use case i meant a "balance" control, like found in analog consoles. Having a width control (A3 style) can be a plus, but not absolutely necessary.

Jonathan (@non-mixer) explained me there are multiple interpretations of what a "simple" balance control can be (i think he meant the "pan law"), and i have to admit that any would fit my needs, as i couldn't tell which has been existing in the various analog or digital consoles i have used in my life.
I have only found an LV2 example here http://www.nongnu.org/ll-plugins/lv2pftci/ where the actual audio code is about 20 lines, so i may be able to duplicate that for a ladspa plugin, until someone did it before me ?
