Have you record armed the track?

There are 2 places to click to record.
On the track.. there is a Record Arm button. That must be clicked.
Then on the transport there is a Record Button.

Arming the track tells Studio One which rack you want to record onto.
The record button on the bi otto tells it to start the actual recording.
