So I hacked my APC40 last weekend; and that resulted in the patch you see here. If you pull the APCP4d MIDI effect onto a track and add a drumrack to it the indicator at the bottom will light up. Then all that’s left to do is to turn the device on and the upper 4 x 4 grid of the APC40 button matrix is now a drumpad. Thanks to the velocity control you can even configure… well; you figure that one out 😀
You can play notes which give you sound and visual feedback, or you can play MIDI clips which will then also give you visual feedback. Turn the device off and the grid returns to its normal (previous) state.
Details: The patch automatically checks your configuration and uses the first APC40 it can find. There is a small bug when playing 2 notes at once (then one button can remain lit) but that’s only a minor annoyance.
