If you use Analog Lab as a plugin in Ableton the controller knobs only work with "All" or Channel 1. If you choose e.g. Midichannel 2 the Keyboard works but not the controllers.
I do not worry about this, because I work with Ableton Macros and a "User"-setup – but maybe this should be improved... (Analog Lab VST is set to "receive all midi channels"...
Could have two reasons... Analog Lab VST is not receiving on other channels than "1" or Minilab is only sending on channel 1 (and not the corresponding channel of the keyboard...)
This is a minor bug but maybe interesting for some users who want to use the Analog Lab-mode...
