AUDIOKIT - Why is the AKOscillatorBank RELASE, DECAY, SUSTAIN, and ATTACK being updated long after I change their values? - audio-player

Question

I have a simple AudioKit app in the works.
I initialize an AKOsicillatorBANK at runtime and allow you to press a button to access a new viewCONTROLLER which has SLIDERS that when changed change the values of the oscillatorBANK properties [releaseDURATION, attackDURATION, decayDURATION, sustainLEVEL].
At the end of the slider's PANGESTURE [state == ended], I call a function that sets the oscillatorBANKS properties to their new values, which are stored in class variables.
I do not know why, but the changes only take effect some time (a few minutes) after the function is called. Does anyone know why this is?
ALSO PLEASE DO NOT COMMENT ON MY CAPITALIZATION STYLE. I PREFER THIS AS IT ALLOWS ME TO EMPHASIZE WHAT I BELIEVE TO BE IS IMPORTANT, WHICH CAN THEN HELP YOU SEE MY TRAIN OF THOUGHTS BETTER.
HERE IS THE CODE. Please note that I ONLY included the code for DECAY within the panGESTURE, because attack, release, and sustain code is all the same design:
// MAIN VIEW CONTROLLER CLASS, GLOBAL SCOPE, INITIALIZED WITH VIEW DID LOAD //
let bank = AKOscillatorBank()
var bankATTACK: Double = 0
var bankDECAY: Double = 0
var bankSUSTAIN: Double = 1
var bankRELEASE: Double = 0
func updateBANKWAVE() {
self.bank.rampDuration = 1
self.bank.attackDuration = self.bankATTACK
self.bank.decayDuration = self.bankDECAY
self.bank.sustainLevel = self.bankSUSTAIN
self.bank.releaseDuration = self.bankRELEASE
print("NEW BANK RAMP [\(self.bank.rampDuration)]")
print("NEW BANK ATTACK [\(self.bank.attackDuration)]")
print("NEW BANK DEC [\(self.bank.decayDuration)]")
print("NEW BANK SUS [\(self.bank.sustainLevel)]")
print("NEW BANK REL [\(self.bank.releaseDuration)]")
}
func prepareforSEGUE() {
if let sliderCONTROLLER = segue.destination as? SLIDERVIEWCONTROLLER {
sliderCONTROLLER.mainCONTROLLER = self
}
}
// SLIDER VIEW CONTROLLER CLASS //
if panGESTURE.state == changed {
// ... update a UILabel to reflect the value to be set ...
decayTEXT = String(format: "%.3f", (self.decayTRANSLATION.truncatingRemainder(dividingBy: 100.0)))
// ... update the MAIN controller variables ...
self.mainCONTROLLER.bankDECAY = Double(self.decayTRANSLATION.truncatingRemainder(dividingBy: 100.0))
// ... protect against values above 10 or below 0 ...
if decayTRANSLATION > 10 { decayVALUE.text = "10.000" ; decayTRANSLATION = 10.01 ; self.mainCONTROLLER.bankDECAY = 10 }
if decayTRANSLATION < 0 { decayVALUE.text = "0.000" ; decayTRANSLATION = -0.01 ; self.mainCONTROLLER.bankDECAY = 0 }
}
if panGESTURE.state == ended {
self.mainCONTROLLER.updateBANKWAVE()
}

By changing the oscillatorBANK.rampDURATION property to 0 instead of 1, I get instantaneous results. However, even though the release is being set to 1, the note can still be heard after 4 or 5 seconds... so...
