Which midi channel are your Microlab set to? Any sound with B3 and VOX presets when using Midi channel 1?
In most of the B3 and VOX presets the upper manual respond to Midi channel 1, the lower to midi channel 2, and the pedals to Midi channel 3.
Other applications are mostly set to respond sound with any Midi channel.
Analog Lab is set to ALL midi channels, but that does'nt mean the individual presets work on ALL channels. It's like i wrote. So please answer if things work, when you set microlab controller to midi channel 1. That what's important. Let Analog Lab be set to ALL midi channels. Do this test in standalone mode first.
If that work, then test in a DAW and be sure you send messages on midi channel 1 to the plugin.
I think this very well can be about learning how things work.
