RMX 500 - LED feedback in plugin mode

Hello everyone,

I'm using the RMX 500 as a plugin inside Ableton, however I'm having a problem with the LED feedback : compared to the standalone mode, the LEDs are dim, and do not follow which effect is activated (ie setting the LPF won't make the LPF LED light up)
Anyone has this problem ?
This is a pretty big flaw when performing live, as in my setup I don't want the RMX to be used as an external device
