The Wheatstone equipment is the iHeart studio audio input and processing
hardware, not the broadcast automation and digital storage control
software.
Wheatstone does audio and AOIP and audio processors, not digital storage and program control / automation. They also do not do the associated traffic and music scheduling software needed to run the content on the storage and program control.
You are talking about hardware for the studio and audio. The systems I am referring to are software based, generally using off the shelf computer hardware to schedule, integrate and broadcast programming through the hardware.

There are other software based systems to run a format or certain aspects of a format like commercials or music and promos. Zetta is rivaled by MusicMaster. Marketron is rivaled by Wide Orbit's traffic and automation. There are lots of simpler systems for smaller stations and markets. None is made by Wheatstone.
Here is an article about all the digital (software) systems used to control the programming or certain aspects of it:
