“I played a simple pattern into Digital Performer. Then I unplugged the guitar from the GK Expander, and moved the patch cables from the MOTU inputs to the outputs. I unplugged the guitar so that the VG-99 would not be receiving input signals from both the guitar, and the computer. VG-99 plays just as if I am playing the guitar parts. Then I connected the GR-55, to hear the same pattern with the GR-55.”
