I think setting up [Send Buses](https://fmod.com/docs/2.02/studio/mixing.html#sends-and-return-buses) for each of your desired effects and using [parameters](https://fmod.com/docs/2.02/studio/authoring-events.html#parameters) to [automate](https://fmod.com/docs/2.02/studio/authoring-events.html#automation-and-modulation) the volume of the send would be the way to go. Here is a simple example using discrete parameters to set the send level to 0db when active and -∞db when inactive: ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/8/8ab41b2978438f5243b74b08ea84dc12e9cad621.png) Note that the signal path would be fixed in this case. Alternatively you could add effects to the event at runtime using [`System::createDSPByType`](https://fmod.com/docs/2.02/api/core-api-system.html#system_createdspbytype) and [`ChannelControl::addDSP`](https://fmod.com/docs/2.02/api/core-api-channelcontrol.html#channelcontrol_adddsp), which would allow you to setup effect chains in any order. --- _[View the full topic](https://qa.fmod.com/t/best-practices-for-setting-up-and-organizing-a-single-programmer-instrument-to-be-effected-by-multiple-event-effects-chains/19083)._
