FMOD won't play more than 1 instance of same event.

[slrdur]

Context:

I'm trying to create a rifle sound for a 2d godot game, and within FMOD I have an event ("Automatic Rifle") with a logic track, so the gun sounds get "airy-er" as the ammo runs out.

The event contains a few multi-instruments all creating one bullet shot.

The event is played currently every 0.1s and the "airyness" goes from 0 to 100 over 10s

The issue:

Every time the event fires it cuts off the previous one, meaning that when the gun is fired at high speeds it sounds choppy and the reverb doesnt work properly.

I cant find any way to increase event polyphony. I've looked in FMOD for polyphony options and they're all at max, and within godot I can't find any polyphony options for the FMOD extension specifically.

Relevant code:

(within a test script - attached to an FmodEventEmitter2D Node)

extends FmodEventEmitter2D

var shotDelay = 0.0
var shotDelayLimit = 0.1
var airModulate=0.0
var airModulateLimit=10

func _physics_process(delta):
	air_modulate(delta)
	play_gunshot(delta)

func air_modulate(delta):
	airModulate+=delta
	self["event_parameter/Ammo Airyness/value"] = airModulate * 10
	if airModulate>=airModulateLimit:
		airModulate=0.0

func play_gunshot(delta):
	shotDelay += delta
	if shotDelay >= shotDelayLimit:
		shotDelay = 0.0
		self.play()
		print("Sound played")
