This is a really wicked xrni that use a phrase with a rettriger effect. The trick is you modulate macros while its rettrigering. You can hear this instrument in action at 0.07 second of my example slowly fading in of full at 0.21. i used this for my bass part + pitch slide up in my melody.
Macro for : Pitch, Surround, Mono, Ring Freq,Ring Wet, Bit crunch, Rate, Volume
