MIDI Multi Channel Recording Set Up

[XORadmin]

The overrides are for midi output, not for the input.
You would need to set midi channel 1-4 record to tracks 1-4 record.
Turn on midi data input.
Make on all 4 tracks an empty pattern.
Press record and be sure all 4 patterns are playing.
All 4 midi channels should record now into the patterns on track 1..4

Of course you can change any settings for these tracks routing to different output channels if needed.

Thank you for such a quick reply!

So, if I understand this correctly, I have to set up 4x MIDI tracks via 'Projects' page 'Track Assign'(?) - Although I might have not explained myself intention properly; I was looking to record into separate columns on 1x MIDI track. Is this not possible?

You can record polyphonic into one track from one channel. But on different channels you would need different tracks. 
If you for example record multiple channels into the same track, the sorting of notes might not be what you seek for.
