Making own instruments for MPC LIVE

Anyone know how you make your own instrument and the keygroup is saved so it is available to new projects like the factory content on the MPC Live?

After creating the program, save it to internal > Expansions > Instruments - this way it will be available via the 'Content' section of the browser. Remember you have very limited space on the internal drive, it's better to save your stuff on other 'attached' disks IMO.
