OPERATING INSTRUCTIONS
FOR
PRO-2
DUAL CHANNEL
MIDI TO CV CONVERTER
_________________________________________________________________
INTRODUCTION
_________________________________________________________________
Congratulations on your purchase of the Kenton Electronics PRO-2 dual channel MIDI
to CV converter, which has been designed to give you maximum flexibility, whilst
maintaining ease of use.
The converter has two completely independent sections - one called Channel A and
the other Channel B - do not confuse these with the MIDI channels - each of
Channel A & B can be operated independently from any MIDI channel.
Additionally, you can have a Wasp port fitted, to run an EDP Wasp synth, and a KADI
port, to allow you to control the notes of some drum machines (TR-808/606,
CR78/8000).
_________________________________________________________________
The BARGRAPH display
_________________________________________________________________
The Bargraph display is used in conjunction with the SELECT OPTION push button. The bar which is lit
(or unlit for inverse display) indicates which option is current. The current option value is displayed in
the dual 7 segment display window and can be edited using the INC & DEC buttons.
A normal bargraph display (one bar lit) indicates that the option is from the Group I list (i.e. MIDI
channel A etc.). An inverse bargraph display (all but one bar lit) indicates that the option is from the
Group II list (i.e. Note priority A etc.).
_________________________________________________________________
THE DUAL 7 SEGMENT DISPLAY
(also referred to as the Window)
_________________________________________________________________
When displaying letters, & numbers from 0 to 99, you will see the digits as you would expect.
When displaying numbers above 99, the following format is used :a dash " - " at the bottom of the left-hand display = 100+
a dash " - " in the middle of the left-hand display = 110+
a dash " - " at the top of the left-hand display = 120+
For example, supposing the display reads " - 7 "
if the dash is at the bottom, this means 107
if the dash is in the middle, this means 117
if the dash is at the top, this means 127
No values above 127 are used.
The two dots at the top of the display indicate when the gates of Channels A or B are active.
_________________________________________________________________
THE PUSH BUTTONS
_________________________________________________________________
SELECT OPTION
Press and release the SELECT OPTION push button and the bargraph display will move on to the next
position. The legend to the right of the bargraph will tell you what the dual 7 segment display is
showing - this can be edited using the INC & DEC buttons.
When you step the display on from "aux B-2 offset" you will see that the bargraph is inverted - in other
words, all but one of the bars will be lit. This unlit bar is then the current option, but from the second
group of options "GROUP II" which starts with "note priority A." If you keep stepping through past
"continue=start" you will come back to the original non-inverted display, or in other words "GROUP I".
When you have edited something you can use the new settings until the converter is turned off, or
you can store them to back-up memory so that they will be recalled when the converter is next
turned on. When you store to back-up memory, the whole current setup is stored, not just the option
you have just edited. To store to back-up memory press and hold the SELECT OPTION button until "st"
appears in the display window. The present setup has then been stored.
Note; If you have edited the current option, the bar will not step the first time you press the select
button after editing.
INC & DEC
Use the INC and DEC push buttons to edit the display and hence the option that is currently selected.
If you hold either button in for more than a second, it will auto-repeat. when the displayed option has
reached its minimum or maximum value you cannot decrease or increase it any further.
The INC and DEC buttons can be used while MIDI notes etc. are being received.

Trimmer adjustments for Channel A & B
_________________________________________________________________
CV INIT (range approx 2 octaves)
- tunes the converter to the synth.
CV SCALE (range approx 20%)
- adjusts the scale of the converter to match the synth. When the converter leaves the factory, this is
set to the standard 1 volt per octave, but some synths may require some adjustment of this control if
the octaves are out of tune with each other.
PITCHBEND (range approx 0 to 1 octave)
- adjusts how much pitchbend is integrated into the CV output. You can set this control to give you
any required amount of pitch- bend from zero to 1 octave.
AUX 1 (range 4 to 14 volts)
- adjusts the maximum voltage available from the AUX 1 jack socket for Channel A - in other words
the maximum voltage available when the source controller for AUX 1-1 is at maximum. This
adjustment is provided as different synths require different voltages.
AUX 2 (range 4 to 14 volts)
- adjusts the maximum voltage available from the AUX 2 jack socket for Channel A - (see AUX 1
above).
_________________________________________________________________
Tuning in your PRO-2 & analogue synths
_________________________________________________________________
It may be that your synth is slightly out of tune, so it will be necessary to tune the PRO-2 to your synth;
1, Tune your synth (when playing from its own keyboard) correctly with your digital synths first. Do this
by adjusting the tuning or pitch knob on your analogue synth whilst playing middle C on both synths.
(To do this, you may need to disconnect the analogue synth from the PRO-2).
2, Now, with the PRO-2 connected to the analogue synth, play middle C on your digital synth. Both
synths should sound. With a small flat blade screw driver, tune in the PRO-2 with your analogue synth
by adjusting the INIT trimmer on the front panel.
3, When your digital & analogue synths are once again in tune, play a key two octaves up on your
digital synth. Now adjust the SCALE trimmer till both synths are in tune. The analogue synth should
now play correctly across it`s range from your master keyboard.
_________________________________________________________________
The OPTIONS in Group I
(the left hand list - normal display)
_________________________________________________________________
MIDI CHANNEL A (range 1 to 16) [factory default =1]
- displays the current MIDI receive channel for Channel A of the converter.
AUX A-1 SOURCE (range pb/vl/af/ 0-120) [factory default =16]
- displays which MIDI controller is being output to the AUX 1 jack socket for Channel A of the
converter. If the window displays a number, then this is the controller which is being used. If you
decrement past 0, you will see "af" which means after-touch, "vl" which means velocity and "pb"
which means pitchbend (note however that pitchbend is already integrated into the CV output).
AUX A-1 OFFSET (range 0 to 127) [factory default =0]
- displays the offset value sent to the AUX 1 jack socket for Channel A when the converter is turned
on, or when it receives a "reset all controllers" MIDI message. For example, this feature can be used if
controlling the volume of a synth using the AUX 1 socket. Setting this value to 127 will mean that you
will be able to hear your synth from power up or after a reset all controllers message, instead of the
volume being set to zero.
AUX A-2 SOURCE (range tr/pb/vl/af/ 0-120) [factory default =7]
- displays which MIDI controller is being output to the AUX 2 jack socket for Channel A of the
converter. Mostly as for Aux A-1 source (see above) but with the additional option of "tr" - trig. If AUX
A-2 source is set to "tr" then a trigger voltage is sent to the AUX 2 jack socket for Channel A whenever
a valid new note is played. This can be used for synths that have a separate trig input for the
envelope generators (such as the ARP 2600).
AUX A-2 OFFSET (range 0 to 127) [factory default =127]
- displays the offset value sent to the AUX 2 jack socket for Channel A when the converter is turned
on, or when it receives a "reset all controllers" MIDI message, as for Aux A-1 offset (see above).
The Group I options for channel B are the same as that for channel A
_________________________________________________________________
The OPTIONS in Group II
(the right hand list - inverse display)
_________________________________________________________________
NOTE PRIORITY A (range lo/hi/ne) [factory default =ne]
- displays the note priority for Channel A of the converter.
If set to "lo" then the lowest valid note played takes precedence.
If set to "hi" then the highest valid note played takes precedence.
If set to "ne" then the newest valid note played takes precedence.
TRIG / RETRIG A (range t/rt) [factory default =rt]
- displays whether normal trigger " t" or retrigger "rt" mode is in operation for Channel A.
If set to " t" the gate is always on while a valid note is playing.
If set to "rt" then a new valid note will briefly turn off the gate to retrigger the envelope generators of
the attached synth.
NOTE PRIORITY B (range lo/hi/ne) [factory default =ne]
- displays the note priority for Channel B of the converter.
If set to "lo" then the lowest valid note played takes precedence.
If set to "hi" then the highest valid note played takes precedence.
If set to "ne" then the newest valid note played takes precedence.
TRIG / RETRIG B (range t/rt) [factory default =rt]
- displays whether normal trigger " t" or retrigger "rt" mode is in operation for Channel B of.
If set to " t" the gate is always on while a valid note is playing.
If set to "rt" then a new valid note will briefly turn off the gate to retrigger the envelope generators of
the attached synth.
ARP CLOCK DIVIDE (range 2 to 24) [factory default =2]
- displays the ratio of MIDI clocks to output pulses from the arp clock jack socketl.
If set to " 2" there will be 1 pulse from the arp clock jack socket for every 2 MIDI clocks. (i.e. 12 pulses
per quarter note).
If set to "24" there will be 1 pulse from the arp clock jack socket for every 24 MIDI clocks. (i.e. 1 pulse
per quarter note).
N.B. MIDI sends 24 clocks per quarter note.
CONTINUE = START (range off/on) [factory default =on]
- displays whether an incoming "continue" message will be treated as a start message.
If set to "of" then incoming "continue" messages are ignored.
If set to "on" then incoming "continue" messages are treated as if they were "start" messages.
_________________________________________________________________
The Mini-jack output sockets
(starting from the right)
_________________________________________________________________
Hz / V CHAN A (option)
- This optional output is for the connection of synths requiring linear control - such as some of the
KORG and YAMAHA synths, where the frequency of the note is directly related to the control voltage.
(This is available only for the channel A output and can be used as well as or instead of the normal
CV output for Channel A.
CV CHAN A (-1Volt to 5 volts +/-1V offset +/-1V pitchbend)
- the control voltage output to connect to the CV input of a synth. This output provides a 1 volt per
octave output (adjustable for initial and scale) with integrated pitchbend.
GATE [V-TRIG] (off= 0 volts on= +15 volts)
- gate voltage output for a standard gate input of a synth.
S-TRIG (off= open circuit on= short circuit)
- gate signal for synths requiring an S-TRIG (short circuit trigger) such as many of the MOOG
synthesizers. The tip of the jack is the trigger signal - if your synth has the CINCH/JONES connector
with two flat pins, the narrower pin is the trigger signal and the wider one is ground.
N.B. use either Gate or S-Trig (not both) as they are two different ways of doing the same thing.
AUX 1 - (range 4 volts to 14 volts)
- voltage output for connecting to an auxiliary input on a synth such as filter control. (see AUX 1 in
trimmer adjustments section).
AUX 2 - (range 4 volts to 14 volts)
- voltage output for connecting to an auxiliary input on a synth such as volume control, can also be
used as a trigger output. (see AUX 2 in trimmer adjustments section).

GATE [V-TRIG] |
S-TRIG | all as above but for Channel B

AUX 2 |
_________________________________________________________________
The ARP CLOCK & SYNC 24 outputs
_________________________________________________________________
ARP CLOCK - (arpeggio clock)
- this output provides a 5 volt clock pulse related to the incoming MIDI clock. The ratio of MIDI clocks
to arpeggio pulses can be adjusted - (see ARP CLOCK DIVIDE above).
A 5 volt positive voltage will be output on the first MIDI clock after a MIDI start (or continue if selected)
is received, & there- after dependent upon the ARP CLOCK DIVIDE ratio.
SYNC 24 - (DIN 24 sync - used on much ROLAND equipment)
- this output provides clock and stop / start signals.
Pin 1 - Stop = 0 volts
Start = 5 volts (or continue if selected)
Pin 3 - 5 volt pulses (24 per quarter note - the same as MIDI)
Pin 2 - Ground
Pins 4 & 5 are not used.
Note that MIDI leads are not generally suitable for connecting to the SYNC 24 socket as they have
different pins connected. Use a 5 pin DIN to 5 pin DIN audio lead - available from a HI-FI shop.
POTENTIAL PROBLEMS USING MIDI CLOCK
When using the MIDI clock in conjunction with the PRO-2 or our retrofits please note the following;
The Kenton add-on cannot sync the arpeggio if it is not actually receiving the MIDI clock. This is not
as silly as it sounds, there are a few points to watch for:-
a) Some MIDI mergers & patch bays actually remove MIDI clock information from the MIDI data
stream or you may have to enable it for the port you are using.
b) Users of CUBASE note that the default for MIDI clock is for it NOT to be sent, you will have to go into
MIDI edit and switch it on.
c) Users of UNITOR/EXPORT on an Atari note that the MIDI clock will only come out of port A (that is
the Atari's own MIDI port) unless you can re-assign it.
One way you can check whether the PRO-2 is receiving MIDI clock is to use the in built MIDI Analyser,
described later in this manual.
_________________________________________________________________
The MIDI sockets
_________________________________________________________________
MIDI IN
- connect this to the MIDI out of your MIDI synth or MIDI sequencer using standard MIDI cables.
MIDI THRU
- This provides a copy of the information coming into the MIDI IN socket so that you can "daisy-chain"
several MIDI devices. Should be connected only to a MIDI IN socket (or not used).
_________________________________________________________________
OPTIONAL WASP PORT IF FITTED TO PRO-2
_________________________________________________________________
The Wasp port if fitted to the PRO-2 MIDI to CV converter works on its own MIDI channel
independently of the two existing channels A & B, making the PRO-2 into effectively a three channel
converter.
To use the Wasp port, use the connecting cable supplied. This has an 8 pin din plug on one end & a 7
pin plug on the other end. Plug the 8 pin din plug into the PRO-2 and the 7 pin din plug into the
Wasp.
As default, the Wasp will respond to MIDI channel 3, this can be changed and stored just like all the
other parameters on the PRO-2.
Use the SELECT OPTION button to step the bargraph display through until you reach 'continue = start'
(position 16) - the message 'On' or 'OF' will appear in the window, now step to the next position - this
has no text beside it but it is the MIDI channel for the Wasp, the display will probably say 3. If you now
step to the next position, this selects LO, HI or NEW notes take precedence. These are the only 2 setups available for the Wasp.
The Wasp responds to 3 octaves of notes only - on a DX7 or other 61 note keyboard. This corresponds
to bottom C# to C three octaves above.
The Wasp does not respond to pitchbend or indeed any other controls except sustain pedal, which
will hold the current note.
The above limitations are design limitations of the Wasp itself.
_________________________________________________________________
USING THE OPTIONAL TR606/808 INTERFACE WITH YOUR MODIFIED
TR606/808
_________________________________________________________________
Connect the special multi-way cable supplied to the TR606 or TR808 and to the PRO-2. The TR606/808
can now be played from your master keyboard/sequencer.
To set the TR MIDI receive channel, press the SELECT button till you are on the 9th LED bar in the
OPTIONS II menu. There are no markings on the PRO-2 box for this option. The current TR MIDI channel
will now be displayed. This can be changed with the INC & DEC buttons, and stored with the rest of
the PRO-2 settings. The sounds will play with or without Accent. A velocity level of over 70 will cause
the sound to be accented, subject to the level of Accent selected on the TR606/808.
Below is the MIDI drum map for the TR-606 sounds;

CONNECTING YOUR MODIFIED TB303 (5 SOCKET RETRO) TO THE
PRO-2
_________________________________________________________________
PRO-2 to TB303
CV CHANNEL A > CV IN
GATE CHANNEL A > GATE IN
AUX1 CHANNEL A > FILTER
AUX2 CHANNEL A > SLIDE
AUX2 CHANNEL B > ACCENT
Set the AUX sources to which ever MIDI controller you wish to control the Filter, Accent or Slide.
If you use AUX2 (or 1) on Channel B to control the Filter, Accent or Slide, remember to send MIDI
controller messages on the MIDI channel channel B is set to receive on to affect the TB303.
Using Slide;
The Channel A AUX2 trimmer on the front panel of the PRO-2 should be set to minimum (fully anticlockwise) and the OFFSET set to zero. To turn the SLIDE on/off, the MIDI controller must be set to 65 for
on, and 0 for off. When the slide is on, all following notes will glide into each other. It is best to play
legato style for good results.
Using Accent;
The Channel B AUX2 trimmer on the front panel of the PRO-2 should be set to minimum (fully anticlockwise) and the OFFSET set to zero. To turn the ACCENT on/off, the MIDI controller must be set to
65 for on, and 0 for off.

CONTROL USING A MIDI TO CV CONVERTER NOT POSSIBLE FOR THESE
OSCAR (WE CAN DO AN INTERNAL MIDI RETRO-FIT TO THIS THOUGH)
THE FOLLOWING POLY-SYNTHS HAVE CV & GATE SOCKETS AND THUS CAN BE CONTROLLED USING THE PRO-2 - NOTE HOWEVER THIS
CONTROLS ONLY ONE VOICE OF THE SYNTH - BUT SEE NOTE #8
PROPHET 5 OBERHEIM OB-X / OB-Xa
NOTES -
1) The Cinch-Jones S-Trig connector commonly fitted to MOOG synths, has two flat blades - the narrow blade connects to the tip
of a 3.5mm jack plug and the fatter blade connects to the body.
2) The connection info refers to channel A, but this could equally well be channel B etc. If you are going to use channel B of the
converter, you would be using the gate, s-trig, aux 1 & aux 2 outputs (as required) of that channel also.
3) All the outputs of the PRO-2 (except the SYNC 24 and MIDI thru) are on 3.5mm jack sockets.
4) Some of the control inputs on synths are mutually exclusive, ie. you wouldn't use the EXT CLK IN of the SH-101 at the same time as
the CV & GATE inputs.
5) References to FILTER control, mean control of the filter cutoff frequency - sometimes also called filter sweep or VCF frequency
control (VCF means voltage controlled filter).
6) We can fit CV, GATE and FILTER control sockets to most monophonic synths if they do not have them already - cost »37.60 (»32.00
plus VAT) in most cases
7) A stereo jack plug has the following connections, tip - ring - and body - in that order. To connect to the ring of the stereo jack
involves connecting the body of the 1/4" stereo jack to the body of the 3.5mm jack - and connecting the ring connection of the
1/4" stereo jack to the tip of the 3.5mm jack.
8) The PRO-2 (or indeed any MIDI to CV converter) is not generally the appropriate solution for the control of Polyphonic synths.
Although a few early poly-synths do have CV & GATE inputs fitted, this only enables you to use one of the voices, so you effectively
get a monophonic synth when using CV & GATE. The way to control poly-synths using MIDI is to get an internal retro-fit, which of
course KENTON can supply and fit for you.

Additional PRO-2 features
_________________________________________________________________
MIDI Analyser
The PRO-2 now has a useful MIDI analyser function. This feature allows you to see what types of MIDI
messages it receives.
To enter analyser mode, you must power on the PRO-2 whilst holding the INC and STORE buttons.
The display will first show `--`, then `nt`. `nt` means the display will show the MIDI note number of any
notes it receives.
Using the INC, DEC, and SELECT OPTION buttons, different types of MIDI messages received may be
displayed;
INC short press `rc` Receive channel
long press `Pc` Program change
DEC short press `cn` Controller number
long press `cv` Controller value
SELECT OPTION short press `nt` Note number
long press `nv` Velocity
For whichever of the above selected, the PRO-2 will display the MIDI value or message type of any
messages that it receives.
Although pitchbend and after-touch are not controllers, when Controller number is selected, `pb`
will be displayed if pitchbend is received, & `af` will be displayed if after-touch is received. If
Controller values is selected, and pitchbend or after-touch are received, their values will be
displayed.
For values over 99 the usual method is employed for displaying large numbers on the PRO-2.
The LED bargraph in this mode operates as a received MIDI message indicator;
1 Note on
2 Note off
3 Pitch bend
4 Controller
5 After-touch
6 Program change
7 Timing clock
8 Start
9 Stop
10 Continue
LED bars 1 to 10 will flash when they receive their corresponding MIDI messages.
To exit MIDI analyser mode, the PRO-2 must be powered off then on again.
_________________________________________________________________
Displaying PRO-2`s software version
_________________________________________________________________
To see what software version the PRO-2 has, hold down the INC & DEC buttons whilst powering up the
PRO-2.
The PRO-2 will then display it`s software version & software build number, then return to normal
operation.
First it will display `40`, then `31`, `00`, finally `71`.
This means `software version 4031, build number 0071,` (current version when this is being typed).
___________________________________________________________
The Kenton Electronics PRO-2 CV converter has a built in mains transformer factory set to 240 volts AC
50Hz unless otherwise marked. The transformer also has a tapping for 220 volts AC, but this adjustment
must only be made by qualified service personnel. A different transformer must be fitted for operation
from 120 volts. An internal fuse of rating 100mA is fitted, but replacement of this should also be
confined to qualified service personnel. (If fitted with A 120v transformer, a 250mA fuse must be used).
WARRANTY
The PRO-2 comes with a 12 month (from purchase date) back to base warranty, (i.e. customer must
