Rekordbox DDJ-SB2 Microphone not working

Hello there,

Downloaded the Rekordbox Trial last Week. I have a Pioneer DDJ-SB2. The Controller works fine with the Software and I want to upgrade to the full version of Rekordbox. Today Ive wanted to test a microphone, but it is not working. I have no mic button in Rekordbox, there is mixer but only mixer and not mixer/mic. Is there no microphone support for the ssb2 for Rekordbox? Without this feature I cant buy Rekordbox...

Thanks
