Yes, thanks rharv. My pref/audio settings were and are just like that. After messing with things more tonight it started working. I don't know exactly what/which thing I messed with that fixed it. Best I can figure is the Record button drop-down menu (via down arrow on record button) was set to "always record both audio and MIDI". (I started the first track with a midi drum pattern for metronome purposes by Fill Track With MIDI Drum Pattern). I changed to "Record audio only" and I was able to record 2 tracks at once as normal. Then I changed it back to "always record both audio and MIDI" and recording on 2 channels is working as normal. As a test I closed the program and re-opened and all is recording on 2 [L + R] channels as normal now even when I have filled a track with MIDI Drum Pattern. I also made sure my bit depth was set the same [24 bits] in RB preferences and in the Behringer interface's ASIO Driver Control Panel. Perhaps that was an issue. Not sure what fixed it and too tire to switch over to MME for test tonight.
The other thing I was doing was hi-liting the 2 track number I wanted to record onto with red and yellow color via Ctrl - Left Click. But now, that doesn't seem to matter anyhow. It automatically creates the left and right channels/tracks like normal when I Keep Take.

Does the noise in your head bother me ?
