An updated Ableton Automap template can be downloaded from here that has the drum pads assigned the correct note values to trigger samples in impulse.

This can be sent to the unit using the ReMOTE SL template editor that can be found on the ReMOTE SL downloads page. or using a SysEx utility application.

Alternatively, the pads can be edited to send out note values C3 - C4 using the edit function on the ReMOTE SL.
