Fig.3 - Expanded setup using two Switch Doctors.
This setup is capable of 8 pedal loops, 4 control function switches, 6 MIDI Program Changes, 16 MIDI Control or Note messages, and
2 MIDI Expression pedals. The first unit is set to Preset Mode for selecting presets, and the synced second unit is set to Direct Mode
for instant access to all of it's loops and switches. For even greater flexibility and control, this type of setup can also be created using
a Decibel Eleven Pedal Palette as the second synced unit.
