Im trying to remap my APC40 to control parameters on Native Instruments Massive synth plug in. I want to keep the presets as they are on the controller (clip launch=clip launch) and change the function of a few of the other buttons/pots (panning pot to filter sweep on Massive for example). The only way i can get MIDI learn to work on the plug in is by turning off the APC40 as a control surface effectively turning it into your bog standard MIDI controller. Clip launch buttons become note keys, you lose all the rest of the APCs preset functions (you have to reassign everything from scratch ). When you open Massive some of the APCs pots are already mapped to the macro controllers so surely you can change some things around without losing all of the controllers presets???????? Any help is much appreciated£ ez

Double check the apc40 manual to make sure you have your midi preferences correct.

You must keep the apc40 set as the control surface at all times.

control surface - apc40
input - apc40
output - apc40

midi port:
apc40 input - track = on, remote = on
apc40 output - track = on, remote = on

now just hit the midi button in session view to re-assign any knobs leaving the rest unchanged.
