Patterns are being edited by note messages

[Eamoex]

I use my sequencer to automate chord changes. Everything is fine, except when I display the pattern page while the sequencer is running, the patterns steps are being edited by the received notes. I would like this not to happen, i.e. make changes to the pattern manually, with the NDLR knobs, while the chord sequence unfolds.

Question 1: what is the purpose of this behavior?

Question 2: can I disable this?
