expert sleepers silent way in ardour

I have set up expert sleepers silent way to generate din sync and send that out via my sound card to start my drum machines in time with ardour.
But I cant get this to work.
I have a midi track with expert sleepers sync as a plugin and use the ext send to send the audio to the correct channel on the sound card. In the io i have midi clock from ardour going to the plugin channel but when I press play the plugin generates audio on correct channel but nothing starts.
Has anyone got any advice or got expert sleepers silent way to work in ardour?
I will also need to use this to generate cv gate from midi data too once I’ve got this working.
