INTRODUCTION 

 

Congratulations

 

on your purchase. The 

PRO CV to MIDI 

is a high specification, fully configurable control 

voltage to MIDI converter, capable of tracking pitch Control Voltages very accurately, be it Volt/Octave, 
1.2V/Octave or Hz/Volt. It also supports pitch bend, modulation and non-quantised continuous tracking 
in addition to two user-assignable auxiliary CV inputs. 
 
The 

PRO CV to MIDI

 also includes an intelligent auto tune feature, to make it as easy as possible to set 

up with your analogue equipment. 
 
 

 

CONNECTIONS 

 
 

 

 

MIDI OUT 

Plug your receiving MIDI device in here.  

(This socket also serves as a MIDI input  for updating the firmware) 

 

CV (-3V to +10.65V usable range) 

Plug your pitch CV connection in here. The scale type (V/Oct, Hz/V, 1.2V/Oct) is set using the menu. 
 

GATE / S-TRIG 

Plug your gate connection in here. The gate type (Gate / S-Trig) is set using the menu. 
 

AUX 1 & AUX 2 (0V to +10V usable range) 

Plug auxiliary inputs in here. These two sockets are assignable to a number of different functions, such 
as MIDI CCs, Note Velocity, MIDI Clock and more 

– 

see parameters 30 & 40

 

DC IN 9V 

Plug  your  power  adapter  into  here.  The  converter  will  take  an  adapter  with  an  output  of  9  volts  DC 
regulated or unregulated, ve. The Pro CV to MIDI is supplied with a  power supply suitable for 
the destination country. Other power supplies can be used as long as their output is 9 volts DC regulated, 
can supply at least 100mA and have 2.1mm ve plug.  
 

WARNING:

 Do not use an adaptor with an output voltage higher than 9V. The 

PRO CV to MIDI 

must not share an adaptor with 

any other device. Failure to observe this will invalidate your warranty, and will probably damage the other device, the 

PRO CV to 

MIDI 

and/or the power supply.
