Hello to you all. 

A few days ago I installed the Zoom app (latest version) to try taking drum lessons. I have a Macbook late 2013, 2 sound cards. Xr18 by behringer (I have 11 microphones for my drums on it) And the Behringer mc204hd sound card. With both sound cards I face the same problem and now I believe that something is to blame from the application.  I can't understand is that when I talk to the microphones (11 microphones) the zoom app normally gets a signal. As soon as I tap with my finger, the microphone only signals on the first tap and then the app stops signaling. If I speak again to the microphones it signals again until the next hit with the finger I can't get a tip unfortunately. Unfortunately the sound of my drums does not pass to my teacher 😢
