Audio FX loading on Instruments Slot - Is this a bug?

[Deif]

I either had never noticed this behavior, or it started on 10.7.4. See the attachment. When I click on the instrument slot I get the option to load Audio FX. Only certain plugins show up. If it's not a bug, what purpose does it serve? 

Edit: I know see that they are MIDI-controlled effect, but how does this work in practice?

i saw that too, but have just ignored it. still, it's a good question: why does this happen? is it intentional, or a bug...?

These are quite probably the same ones that you can load from the bottom entry AU MIDI-controlled Effects.

It's Logic's (in my opinion) completely backwards way to get MIDI into plugins that can use it. You put the FX into an instrument slot (this is how you get MIDI into it), then you select the source track via the Sidechain Menu (this is how you get audio into it). 

Did I mention I think this is completely wcakbrads ?

It's definitely, um, "non-intuitive" and less than optimal, but requires less internal messing with the engine to get MIDI to plugins...

...which is pretty exactly what my landlord must have thought when he pointed me to the ladder leading into the upper floor, I guess.
