Midi Bass not receiving notes on presonus studio one

i have tried the tutorial and when i load midi bas plugin and i play my bass i cant see no action on midi bass is not receiving any audio input but the tracks is already in monitor mode
what else can be done to make it work

-are you sure you loaded MIDI Bass on an audio track? ( on an instrument track it will get no audio from your bass)
-windows: you have turned of dropout protection in S1 settings?
-does the channel have live monitoring when no plugin is loaded?
