How to identify which instrument created the MIDI if using "All Inputs" with multiple instruments?

[swabygw]

Theoretical question here: If we are using a midi controller which governs two midi instruments being inputted into Studio One and S1 receives the exact same midi note info from both (as viewed in the Midi Monitor) and we record that information on an instrument track where "All Inputs" is selected, the instrument track shows both midi notes (one on top of the other). Is there a way to identify which instrument created which midi note?

Btw, I fully realize that this confusion can be avoided by specifying the input on the track, but curious what really happens when "All Inputs" is used and duplicate info is received by S1.

P.S. This scenario is easily replicated with the Arturia 4x4 interface which will accept both a midi input and a USB input and create two inputs in S1 and the midi monitor will show that S1 has received two midi notes. Recording on an instrument track will show two notes: one on top of the other.

"All Inputs" might be handy if you're a (say) keyboard player who prefers playing your right and left hands on different instruments such as is common playing live — which doesn't make sense with MIDI data but old habits die hard, or maybe you play bass using foot pedals, but to play the exact same notes on two different instruments ... I can't see why anyone would do that.

As soon as the notes are recorded, there's no information about the source MIDI input anymore. The notes don't carry channel or device info. So to really keep them separate I would create another instrument track (e.g. by duplicating the track) and set different MIDI inputs. You can merge them anytime later - or just select both instrument parts and edit them in one common Note Editor view as shown in this video:
