I'm looking for someone familiar with the Tascam 2488 recorder. I am trying to assign the multi-effect to more than 1 input. When doing so, the first assigned multi-effect is muted. The recorder only lets me assign 1 input/channel only. How can I save the multi-effect to use on multiple channels? I am using the guitar effects when trying this. Also, I am having difficulty getting effects for vocals. Any guidance or suggestions will be helpful. Thanks!
