Monitor synth

artist 11 Mac
I have an analog synth hooked up and can record and playback in Cubase ok on an Audio track
but the only sound is monitored thru my interface.In Cubase the meter doesn’t move and the stereo out meter doesn’t move for that audio track…
And there is no monitor button on my tracks…What would you do…or is it ok the way it is??

I would use the Track Control Setting to configure the Monitor button. And then I would engage the Monitor button

thanks
