I figured it out last night but it is a totally different fix with Reaper. I had, days ago developed two different Reaper sessions which one, as it turned out would detect and the other wouldn’t. I compared both and the only thing I could find was Scaler was listed below EZKeys inside of the track I was trying to detect. I deleted the EZKeys instance, then reloaded it. Scaler was then on top as seen in the screenshot.
I didn’t think it would make the difference, but it does matter in Reaper.
