Here is my issue: I have a Rocktron Voodu valve rack effect, which has a front input connection only. In order to have to unplug my guitar transmitter from my DI box and replug into the Rocktron effect, I would like to somehow link channels on the SM Pro 4 channel Di box. This would allow me to include the Rocktron with other effects on the various mixer channels. I would appreciate your advice on how or whether this can be achieved. Many thanks in advance
