Vsti Undo

How can I enable undo/redo for VSTI/ VST in renoise?
When I use for example noisemaker in reaper and try out some filter settings I can hit CTRL Z and
the synth goes to previous state, when I do this in renoise, renoise thinks I want to undo insterting noisemaker.
How can I let renoise do similar behaviour like reaper does and go to the previous setting I had the synth set to?

You might need to check the “Enable keyboard” checkbox in the lowerleft frame corner of the VSTI dialog for that. Noisemaker has its own native undo response to this keyboard combination, but in Renoise, keyboard focus isn’t automatically given to the plugin’s interface unless you check that checkbox.
