FS8M External MIDI Interface 1.0   p 5

 

MIDI Control 

 
Overview 

The MIDI interface takes the place of the FS8 pedal, and controls all functions that were 
originally controlled by the pedal. No more. No less. In other words, the interface does 
not provide any additional control beyond that which the FS8 provides. 
 
The interface responds to MIDI Program Change Commands only. 
 
It can be controlled by the Rivera Head Master foot-operated MIDI controller or by any 
standard MIDI controller. 
 

Combinations And Separate Functions 

Two types of commands are provided - Combinations and Separate Functions. 
 

Combinations 

When the amp receives a Combination Command, ALL MIDI controllable values are 
changed. 
 
For example Program Change 43 selects: 
 Channel 

 

Boost 1 OFF 

 

Boost 2 ON 

 

Boost 3 OFF 

 

Effects Loop OFF 

 

Separate Functions 

Program Change commands for separate functions have also been defined. 
Separate functions change ONE value only, leaving all others unchanged. 
 

Knucklehead Reverb Compatibility 

The program change commands were chosen to be as identical as possible to the 
commands used by the Knucklehead Reverb. The only difference is that the FS8 does 
not control Reverb (because the Bonehead has no reverb). This design explains why 
there is a column marked UNUSED on the chart.
