How to set up: MIDI keyboard -> OT -> Synth?

thanks, but it doesn’t work that way
I didn’t mention that I also tried to connect it that way - OT MIDI OUT -> Tetra MIDI IN
In this case I can control Tetra by pressing OT trigs, but It doesn’t correspond to MIDI keyboard.

When I am using OT MIDI Thru -> Tetra MIDI IN, Tetra corresponds to MIDI keyboard, but doesn’t correspond to OT trigs and I can’t record a sequence.

How can I set up OT so I can use MIDI keyboard as master keyboard to record external synth sequences ?

I have read the manual and watched tons of tutorials, can’t believe it is so difficult :frowning:
