In Reason DAW how do I send MIDI from two keyboard sources into two discrete instruments simultaneously?

I hardly ever use Reason outside of the plugin version, but thought I would revisit the DAW version with this graphics update on the horizon and immediately hit a snag trying to record from keyboard 1 into instrument 1 same time as keyboard 2 into instrument 2.
Could only find references to needing to set a Master Keyboard, but that didn’t help. I’m sure it’s simple, but I couldn’t figure it out.
