Ok thanks for the quick response.....
I have already purchased No. 3 MPX24 preset with the relevant mainboard "preset 24 LEDs," I have a doubt:
to connect the LEDs to be placed under the keys reversed (presets) use the mainboard preset 24 LEDs, while the key switch inverted (memories), I have another mainboard connected in series with the LED preset24? and what? in the diagrams is not very clear ...
Thank you very much

The preset Board MPX 24 has a JUMPER which allows to connect real switches ( like inversed Presets Keys in a real Hammond ) or simply touch push down buttons with LED´s in it.
But You also can connect real switches and parallel LED´s ( without touch switch )
