Since I installed the vocalizer in my MIDjay, my microphone reverb stting is being changed by midi files.Not my vocalizer reverb setting but the microphone reverb setting. I have saved the mic reverb, echo and volume settings, I want, to power up, but certain midi files will change the reverb setting.How is this possible? It makes the vocalizer unusable. Is anyone else experiencing this problem? AJ?
