Parameters changes not affecting transitions

FMOD Studio
1

I’ve been working on a 3-part spell sound (start, loop, end) and the transitions work properly in Studio when played individually (set the parameter in studio, play, stop, set parameter, play), but real-time changes to the parameter do not affect whether my loop continues or not. I’m unsure if this is a bug or if I’ve set my transitions up incorrectly.

I’m also encountering a related problem with my code to control this in Unity. It appears that my parameter change is not being recognized by FMOD according to a Profiler session I recorded. I have tried using both the setParameterValue and setValue commands, but neither work (and setValue is giving me a “‘FMOD.Studio.ParameterInstance’ does not contain a definition for ‘setValue’” error).

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using FMODUnity;

public class PlaySound : MonoBehaviour {


	[FMODUnity.EventRef] 								
	public string ZonePath; 
	public FMOD.Studio.EventInstance ZoneEvent;
	public FMOD.Studio.ParameterInstance ZonePI;
	public float SpellPH = 0f;
	
	void Start () {
        ZoneEvent = FMODUnity.RuntimeManager.CreateInstance(ZonePath);
        
    }
	
	void Update () {
		if (Input.GetKeyDown(KeyCode.Return))
		{
			ZoneEvent.start();
            ZoneEvent.getParameter("SpellPhase", out ZonePI);
        }
		else if (Input.GetKeyDown(KeyCode.RightShift))
		{
			ZoneEvent.stop(FMOD.Studio.STOP_MODE.ALLOWFADEOUT);
		}
		
		if (Input.GetKeyDown(KeyCode.KeypadPlus) && (SpellPH <3))
		{
            SpellPH += 1f;
            ZonePI.setParameterValue(SpellPH);
        }
		else if (Input.GetKeyDown(KeyCode.KeypadMinus) && (SpellPH>1))
		{
			SpellPH -= 1f;
            ZonePI.setParameterValue(SpellPH);
        }
        
    }

I just have this script attached to the same “empty object” that my ambiance emitter is attached to.

FMOD.Studio.ParameterInstance does contain a definition for setValue, but it does not have setParameterValue as that is in the FMOD.Studio.EventInstance.

Nothing else immediately stands out as a problem, all the FMOD functions return an FMOD.RESULT which may help with debugging.
