Hi, this is because the DAW template you’ve chosen doesn’t send/receive to the midi port 1 of the Keylab. The solution is to place your Keylab into the Ableton Live DAW mode. This way, the pads will be bound to the DAW port.
You might even want to try my own script, because I think it covers what you want to achieve, though not exactly in the way you imagined it. For example, we select tracks by using the 8 buttons below the faders (which are also used for mute/solo/record/monitor).
Here’s a screenshot of the pads assignments:
As you can see the open/close instrument is mapped to a pad.
Concerning presets change I have bound it to the jog wheel while we have Pad 4 held. Without it held, it performs bar± (Nav L/R). If we hold Pad 1 it navigates Up/Down, with Pad 2 we alter the BPM and with Pad 3 the horizontal zoom.
The script is here, you may find it useful either by simply using it or by getting ideas.
