from keybordin CHOP to Base COMP

Hello everyone, I am new to TouchDesigner. So please forgive me… Where can I find information on the following task: I have assigned two keyboards, 2 and 3, in the keybordin CHOP on my tablet – I would now like to link these to my Base COMP - control panel, but I keep failing. I was able to set up faders intuitively, but buttons (1-0) are complicated. A simple signal – not a continuous signal when the button is pressed. Dear community – where can I find information, many thanks, Jens
