Recording with a virtual instrument

hoping someone can help, im using Studio One pro. im trying to record from a virtual instrument like Mai Tai.

the steps are

i create a new song using a blank template

i either drag Mai Tai over to the Tracks section or create a new instrument track from the menu

i select a preset

i Arm the track for recording

then i press the record button

using the virtual keyboard on Mai Tai i play some notes

i stop recording

nothing is recorded.

i can hear the notes but in the track Activity Monitor there is no activity when playing notes

The mixer shows activity when playing notes

if i tu off Monitoring on the track, i can still hear notes when playing

what am i doing wrong?

Thanks
