Where is the serial number

I could not understand where is the serial number
Also when I try to record on Logic Pro
I only hear voice from my microphone
Pls help me

Hi Mano

A serial code is not needed if you purchase the software only version from our website. The license is attached automatically and available to download from your Vochlea account here - www.vochlea.com/download

Just to clarify Dubler is not a plugin, and will not appear in any plugin list in Logic. Dubler is a standalone app that connects to Logic as a MIDI controller. If you haven’t seen it already I’d recommend watching our video on setting up with Logic here - https://vochlea.com/tutorials/setting-up-with-logic-pro-x

If you have any questions or need any help setting up let me know
