Hey, everyone. I've been playing around with my bass and the 3 OSC Synth block on my Helix and have arrived at a sound that I'm mostly happy with. I say mostly happy because whenever I pluck the bass strings there's a strange, high-pitched sound that is produced. Is there an effective way to get rid of this sound while maintaining the rest of the tone? It's hard to explain, so I've attached a recorded sample. RL.mp3
