Hi, An option could be using `Transceivers` ([FMOD API | Event Reference](https://fmod.com/docs/2.02/api/effects-reference.html#transceiver)). I explained how you could use `transceivers` here: [How best to Setup Synchronised Multiple Events in Studio for Unity? - #2 by Connor\_FMOD](https://qa.fmod.com/t/how-best-to-setup-synchronised-multiple-events-in-studio-for-unity/19921/2). This is using `transceivers` to play a source event at multiple locations while keeping everything in sync. You will need to get a reference to the `transceiver` DSP using [getChannelGroup()](https://fmod.com/docs/2.02/api/studio-api-eventinstance.html#studio_eventinstance_getchannelgroup) and then [getDSP()](https://fmod.com/docs/2.02/api/core-api-channelcontrol.html#channelcontrol_getdsp) using the [dsp.getType()](https://fmod.com/docs/2.02/api/core-api-dsp.html#dsp_gettype) to make sure you have the right one. In the `transceiver` [FMOD API | Core API Reference](https://fmod.com/docs/2.02/api/core-api-common-dsp-effects.html#fmod_dsp_transceiver) you can see the `channel` is in the 2nd index so we will use `dsp.setParameterInt(2, 0);` to set the `channel` number for the event e.g. the radio station number. If you need a script reference find attached the code I used. Hope this helps!
