Recording In Mono/1-channel?

How do I record live audio with Renoise using only one audio channel? If I can’t, how do I convert a sample that only has sound on the left side to both channels without having to import the sample into another sample editor?

see at the top right, select L or R

also you can resample to 1 channel by clicking this button ( ) in the sample editor screen (bottom left)

DUH!!! I’m such a dufus!
