If anyone else is looking for something similar this might help - this is a KeyLab 49 map for Spark. I've set it so the pads follow the Spark layout.
Please adjust the velocity settings per pad to suit your own playing style!
Or another way is just to use midi learn:
6.7.1 Assign a MIDI note to pads
Click holding [Cmd] on Mac / [Ctrl] on Windows on [Pads] #115 to #122 and press a button or key on your MIDI controller.
