MIDI Keyboard+USB midi, Digitakt, Logic pro

This is my first post, please help! :sunny:

Question 1

Goal: Control Digitakt via a MIDI Keyboard connected with USB MIDI, using auto channel(14).
Problem: Works well with Track 1-8, then Digitakt went crazy when it goes to MIDI A(to control a software instrument)…

Question 2

Goal: MIDI A controls software instrument in Logic pro.
Problem: Seems it is affected by BPM? At a low BPM(say 40), there will be missing notes.
