Converting a Broken Roland SPD-S into a MIDI controller

[Dujat]

Hey i had a Roland SPD-S and it broke (Internal Memory Damage), i have contacted music stores and the only way to get it fixed it to send it to Roland and this will cost as much as buying a new one, which is not really an option.

My plan would be to use the 9 drum triggers and bypass the brain of the SPD-S to make it into a simple MIDI controller for Ableton live.
I am not sure if i can use what i have already or will i need to buy new parts and how to make this.

here is a picture of the pads;
