Aux 1 maximum voltage (default: 100) 

 
Range   

0 to 100 

= approx. 0 to 10Volts 

– so each step of one is approx. 100mV 

 
These two parameters set the minimum and maximum expected voltages for Aux 1. The MIDI output 
data will be zero for the minimum and below, and 127 for the maximum and above.  

Note:

 if the minimum value is set greater than the maximum, the response will be inverted 

– i.e. a lower 

voltage will result in a greater CC value etc. If both values are set the same, the input is treated as a 
switch 

– i.e. if the input signal is greater than the max/min value, the MIDI message will be fully on.

Clock in 1 PPQN (default: 24) 

 

The following can be selected; 
48, 24, 12, 8, 6, 4, 3, 2, 1 
 
Sets the number of pulses-per-quarter-note expected to be received to output MIDI standard 24 cpqn 
when using Aux 1 for clock input. 

 
40 

 

Aux 2 controller number (default: 7) 

 

The following can be selected; 
CCs 0 to 119 

 

[0 to 119] 

CCs 0 to 31 (High res)  [H0 to H31] 

(CCs sent as two messages giving higher resolution) 

Start/stop 

 

[Stt] 

 

(best way to get to these is often backwards from zero) 

Clock   

 

[clk] 

 

[See note 5] 

Pitch bend 

 

[Pbd] 

Velocity  

 

[vEL] 

Chan. Aftertouch 

[Aft] 

 
Sets which MIDI controller / message Aux 2 is assigned to. 

Note:

 if either Aux 1 or Aux 2 is set to velocity, they will override the fixed velocity value (parameter 14). 

If both are set to velocity, then the most recent message takes priority.

Aux 2 minimum voltage (default: 0) 

 
Range   

0 to 100 

= approx. 0 to 10Volts 

– so each step of one is approx. 100mV

Clock in 2 PPQN (default: 24) 

 

The following can be selected; 
48, 24, 12, 8, 6, 4, 3, 2, 1 
 
Sets the number of pulses-per-quarter-note expected to be received to output MIDI standard 24 cpqn 
when using Aux 2 for clock input.
