Have you downloaded the Latest H9 Control app from either the App Store for iOS or direct from Eventide https://www.eventide.com/AudioDivision/Support/Stompboxes/H9.aspx for the Mac / Windows versions?
once you have downloaded the editor, you will have to also upgrade the firmware of the H9 from within the H9 Control App.
to do this connect the H9 to the device with the latest version of H9 control installed.
Start H9 control.
select the "Pedal" button on the bottom toolbar, then "Update Stompbox's Software"
Once both the pedal and the control app are updated you should be able to see EQ Compressor as purchasable option (for free at the moment)
hope that helps
