Can not get midi side chain to work in Ableton
Can't get midi side chain to work at all. When I press on the half circle dots and then route through the side chain container to another midi track nothing happens. What am I doing wrong?

Hi Richard,
You need to make sure MIDI data is being routed to the plugin: you should see the little MIDI light pulse at the bottom left of the interface. Also, check that MIDI is enabled in the MIDI Learn menu. No need to do anything with side chains: that is for routing audio data.
See "Routing MIDI to effect plug-ins" in this help topic:
