Clock Settings DIP switch 

The Clock Settings DIP switch allows for direct 
configuration of 500R8’s clock source when no USB 
device is detected. The switches also provide a failsafe 
that Cranborne Audio can implement in the unlikely 
event that an issue develops with MasOS or Windows 
software panel control. 
 

Note: 
Clock Settings DIP switch is not currently 
operational on v0.9 firmware. Clock Settings 
are currently changed using the USB control 
panel for windows, or Audio MIDI setup for 
macOS. 

 
 
 

 

MIDI I/O 

500R8 features a full complement of MIDI I/O 
integration via standard 5-pin DIN connections. MIDI 
allows live performance and synth-based workflows to 
integrate seamlessly with 500R8. 500R8 essentially 
converts MIDI information and sends it down USB into 
the host device for recording of midi note or program 
change information.  
 
The MIDI output can be used to fire-off note or program 
change information to external equipment for MIDI 
instruments and integrating synths into your workflow.
