Not sure I should post this here or as a feature request.
When you modulate parameters on an LFO, it displays the movements in real time on its graphic display at the bottom, but this is not the case with Envelopes or Functions (Scale parameter). You see the changes when altering them manually, but once they're modulated they remain static.
Thankfully you can still see the end result in the middle strip, but it would help to have that behaviour consistent across all mod sources at the bottom.
