These tools for the Novation Impulse 61 master keyboard were created by Audible Distortion. They are free to use.
This is an editor for the System Exclusive Midi data used by the Novation Impulse 61 keyboard for the program templates. (It also should work with the 49 keys version.) The editor allows to modify all parameters (zones, buttons, faders, drum pads, etc.) that you can also change for a template with the menu of the keyboard directly, just with a more convenient interface. It operates on syx files, so you need an application to load/save/send/receive SysEx Midi data.
