The Noisy Volca Sample Problem

I apologize if you came here actually seeking a solution to this problem. If you know of one, please leave a comment. I do know that i ve only experienced this digital noise only when running the Sample through a mixer or a pedal. Even in this instance, the noise was only apparent through the main out of the Tascam Model 12, but not while recording that channel. Please feel free to leave any questions you may have and I ll try and answer to the best of my knowledge. Thanks for tuning in
