The pads on the Laboratory keyboard trigger only notes in Scene mode, not audio loops nor FX.

Close any running application, then:

1. Update your Analog Laboratory to the latest version.

2. Launch the Laboratory MIDI Control Center, if the value is incorrect reprogram the pads to notes 120, 121, 122 and 123. "Send to Keyboard", then close the application.

3. Launch the Analog Laboratory standalone synthesizer, do [Cmd]+click (on Mac) or [Ctrl]+click (on Windows) on the virtual pads and use "Learn" function reassign them correctly to the controller pads.

Now your software+hardware bundle should synchronize seamlessly: in Scene mode the loops should trigger as they should.
