Reply to MFP questions for Ableton

Hello all,

Two quick questions regarding use of a MIDI Fighter Pro in conjunction with Ableton:

1) Is there a way to have the light next to the button that I'm pressing stay lit to reflect the toggle state (on/off) of the effect.? Example, if I have a specific button to activate a delay effect for Deck A in Ableton, and then switch to Deck B with the crossfader can I easily tell if that effect is still activated in Deck A without having to reference the Ableton interface on the laptop.

2) Is it possible to have an effect activated/deactivated when a controller button is held down and then let go.

Thank you!
