Hello, I have an FMOD Event I set up with a local parameter called “Power”. It’s a looping hum sound that gets both higher in pitch and also louder as the Power param moves from 0 to 1. In FMOD Studio, moving the parameter works as designed. However, when this sound is playing in Unity, adjusting th…

Thank you for that final project. Could you please make sure that these two preferences match: [image] and to be safe rebuild your banks? The issue may be with a legacy setting bypassing the pitch shifter if these two values are different.

Thank you for the images and the code. Could I suggest adding a Studio::EventInstance::isValid() call after retrieving the instance? EventInstance instance = events[eventName].EventInstance; if (instance.isValid()) // Manipulate params else // There is an issue retrieving the instance Do y…

[image] Connor_FMOD: if (instance.isValid()) Thanks for the response and the suggestion. This method returns a DOTween tween, so it’s not super straightforward to make the proposed changes, but we can use the following method for now to isolate our testing from any tweens or fades, just setti…

Thank you for the update code, I was able to test that on my side and it does seem to be working. Would it be possible to package the project, with banks included: [image] [image] and upload them to your profile, please note that you need to register a project with us before uploading to your pr…

Yeah, you bet. Our project is really massive, so I wanted to give you a limited test case. I deleted all the Events and Assets I could that weren’t related to this particular issue and then just as a test wired this limited project up in Unity to verify the issue is still happening, and it is. So ho…

Thank you for the project. I have tested with some of my audio files and I am not sure if it is the expected behaviour. Would it be possible to share just the build banks? That way, I can load them in my test scene, play the same events you have, and then record a profiler session to confirm it is …

Of course, no problem. I’ve uploaded our Build folder compressed as Build.zip. Let me know if you need anything else from me. Thanks.

Thank you for sharing the built banks. Something I noticed, you are automating the Pitch value of the Pitch Shifter from 0.5x - 1.0x. In the Docs: FMOD Engine | Core API Reference - Effect Parameters . It notes 0.5x will pitch the audio one octave down and 1.0x will not change the pitch. The issue ma…

Thanks for your response. Unfortunately changing the pitch range of the automation from 0.5 to 2.0 does not seem to have any effect in Unity. It does, as expected, change the pitch range from an octave below to an octave above the base pitch when playing the Event and adjusting the parameter directl…

Thank you for the clarification. Would it be possible to add my logging code and ensure the value is being changed on the DSP? I found the correct index by using the following: instance.getChannelGroup(out FMOD.ChannelGroup mCG); mCG.isPlaying(out bool playing); if (playing) { mCG.getNumDSPs(ou…

Thanks, this is helpful, and I really appreciate the level of support you’re providing. I’ve imported and played back the profiler recordings you sent. In both of them, I can clearly hear the pitch changing as expected, so that bit is definitely working. Back to Unity: Here are the logs. I increas…
