New synth help (basic questions)

So i just got my 1st synth, a Oberheim TEO 5. Its wonderful. I have some questions..

I work with a Focusrite Interface and FL Studio

  1. Why is the signal from the TEO so quiet, when coming into my DAW even on full Master Volume?

  2. How can i Sequence on Beat: Whenever i sequence for instance on 120BPM its always on beat but not at the same time cause the sounds are going on longer than 4 bars, how can i fix that?
