Not as far as I know. The last time we researched Arrakis it was not going to work. The situation might have changed but I haven’t looked for some years.
Spinitron cannot import schedule information at all. The only way to get it in there is through the web UI.
Spinitron allows output of the schedule in two ways: via the API or via web integration. Either of these can be used to eliminate the WP/Spinitron redundancy. It might be possible to use some custom scripts to feed data from the API to Apex.
First, the above list is old and therefore probably has errors or updates necessary.
Second, getting now-playing info from automation into Spinitron is going out of fashion. A lot of stations have switched to using automatic music recognition even though it can’t know what album you’re playing.
Third, we’ve never done any program schedules integration with automation and I don’t recall discussing it before.
There’s always MetaRadio which integrates Spinitron as both an input and output. Free trial.
