General Kenton FAQs

Q: Can Kenton supply me with a cable to connect my Juno-60 to my Roland MSQ-700?

A: Yes, we can build you a custom cable for this purpose. The price of the cable depends on what you want it to do.

There are three options:

  1. Juno-60 -> MSQ-700
  2. MSQ-700 -> Juno-60
  3. Bi-directional

Cables 1 & 2 cost £35.00 + VAT; cable 3 costs £45.00 + VAT.

Q: What is the 'Gate to S-trig converter lead' on your price list for?

A: This lead is required if you have a synth with an S-trig input, but you are using a MIDI-CV converter which does not output S-trig. The cable converts the MIDI-CV converter's Gate signal into a Short trigger (S-trig) , enabling you to drive the synth.

Please note that this cable is only needed for use with other manufacturers' equipment - all Kenton MIDI-CV converters have S-trig as standard.

Q: What do the MIDI note numbers mean?

A: Middle C on a keyboard is MIDI note #60

This means that the range for a standard 5 octave keyboard is #36 to #96 and for a full 88 note keyboard is #21 to #108. The notes are sometimes given names like C1 C2 etc. however there is little standardisation of this scheme so it is not a reliable indicator of the note which will sound.

MIDI-CV converter FAQs

Q: I have a Pro-Solo mkII. When I hit a key on my MIDI keyboard, nothing happens, but when I let go of the key, I get a sound out of my ms-20. Why?

A: You need to set the "Gate Type Select" (parameter #16) to S-trig. It will show S_ (S and line at the bottom). Remember to save the setting. (note for Yamaha CS-5/10/15 synths this would be S- (middle line)

Q: On the Pro-Solo mkII, if the main cv/gate output is set to Hz/Volt will the Aux1 output also automatically be switched to Hz/Volt or will it only work via Volt/Octave?

A: Neither! - The Aux output on the Solo is not controllable by MIDI Notes so there is no "octave" for it to be related to.

Generally the Pro-Solo Aux1 output is intended to be used with controllers (CCs) - the Aux output can be set with min and max values which automatically scale.

The Pro-2000 mkII Auxes on the other hand CAN be set to MIDI notes, and when set to be controlled by MIDI Notes they are always volt/octave, but otherwise they are the same as for the Solo. Each main output A & B of the Pro-2000 mkII is independently assignable to Volt/Oct or Hz/V or 1.2V/Oct.

Q: How do I sync the arpeggiator on my synth to MIDI clock using the Pro-Solo?

A: Answers differ depending if you have Pro-Solo mk1 or mkII -

For mk1 - The Pro-Solo will operate in either sync mode, or CV mode, but cannot perform both tasks simultaneously. This is because in sync mode, the CV, Gate and Aux sockets are used to output the required clock pulses. If you want to clock your synths arpeggiator, put the Solo in sync mode by switching it on with the 'inc' button pressed and connect the 'Aux' output jack to the clock input jack on your synth. If your synth requires a DIN Sync-24 type signal use the Pro-Solo Sync-24 adapter cable available from Kenton.

For mkII - If you want to clock your synths arpeggiator, connect the 'Aux1' output jack of the Solo to the clock input jack on your synth and select clock as the controller using parameter #20. If your synth requires a DIN Sync-24 type signal use a standard 5 pin DIN cable plugged into the Thru/Sync output on the Solo and select sync 24, using parameter #42 .

Q: How can I change parameters (for example the speed of the LFO) on my Pro-Solo mkII using SysEx

The generic string required for controlling anything on the Pro-Solo mkII is as follows:
F0 00 20 13 03 20   PL   PH   DL   DH   F7

where
all values are in hexadecimal
PL = parameter low byte
PH = parameter high byte
DL = data low byte
DH = data high byte

Example 1 - to set LFO speed value to 36

LFO speed address is 1E - so PL will be 0E and PH will be 01
data value of 36 (decimal) = 24 (hexadecimal)
so DL will be 04 and DH will be 02
putting these values into the string above gives

F0 00 20 13 03 20 0E 01 04 02 F7

or for data value 37 (25 hex)

F0 00 20 13 03 20 0E 01 05 02 F7

or for data value 57 (39 hex)

F0 00 20 13 03 20 0E 01 09 03 F7

Example 2 - to set LFO waveshape to sample and hold

LFO waveshape address is 1F - so PL will be 0F and PH will be 01
Sample and hold is data value 8 (see note 7 in sysex section of manual)
so DL will be 08 and DH will be 00

putting these values into the string above gives

F0 00 20 13 03 20 0F 01 08 00 F7

In practice the data value will vary (from your slider or knob), so your controller needs to insert the data in the correct format (split into two bytes in low/high order) into the string. Different controllers do this in different ways, I can't advise you on that.

You also need to restrict the range your controller sends for the different data values needed - so for LFO speed, restrict the range to 0-127, for LFO waveshape the range should be 0-8 etc.

Q: How can I change parameters (for example the speed of LFO 1), on my Pro-4 using Sysex?

A: To change LFO 1 speed on a Pro-4 send the following (Hexadecimal) string from your sequencer or MIDI controller.

F0 00 2V 13 04 20 02 06 0L 0H F7

V is the device number in hex 0 to F (device #1 = 0 and device #16 = F ). 0L & 0H are variable bytes that indicate the speed.

Example Sysex String to set the speed to 90 decimal (the default value)
F0 00 20 13 04 20 02 06 0A 05 F7

You first need to convert the 90 decimal to hex, which is 5A - but the data has to be sent in the order lo, hi, split into 2 bytes, so you send the variable speed bytes as 0A & 05.Turning this to read top to bottom:

F0 begin sysex message
00 Kenton sysex id
20 Kenton sysex id
13 Kenton sysex id
04 Kenton product code (Pro-4)
              For this product the above 5 bytes are always the same
20 data type and device number
02 address lo (address for lfo speed 1 is 62 hex)
06 address hi
0A variable data lo byte
05 variable data hi byte
F7 end of sysex

Q: How can I change the operating voltage of my Pro-2000 for use in another country?

A: There is an internal switch to set the voltage. There are two settings 115V (covers 85V-130V) and 230V (covers 170V-260V).

We recommend that the following procedure is performed by a competent service engineer.

A Pozidrive or Supadrive screwdriver is needed, anything else will destroy the screw heads.

1) Ensure the mains power cable is not attached.

2) Undo 4 screws in the top of the Pro-2000.

3) Undo 2 screws on the left side of the unit (as you look at the display).

4) Undo the 2 screws on the right side of the unit that mirror those on the left - DO NOT UNDO THE 3RD SCREW.

5) Remove the lid - there is an earth strap which attaches the lid to the case. Leave this connected.

6) Near the mains switch there is a voltage switch - slide the switch to change the voltage.

7) Ensure the unit is on a flat surface.

8) Replace the lid.

9) Replace the 4 screws in the top of the lid - very lightly done up.

10) Replace the 2 screws each side - very lightly done up.

11) Tighten the 4 screws in the top.

12) Tighten the 2 screws on the left side.

13) Tighten the 2 screws on the right side.

14) Put a label on the back covering the existing voltage rating, stating the new voltage.

15) Done.

N.B. If changing from 115V to 230V, all that is needed is to peel off the sticker which says 115V. The case is silk-screened with 230V.

Q: How can I change the operating voltage of my Pro-4 for use in another country?

A: There are some jumpers inside the PRO-4 to change voltage, all voltages need 3 jumpers set. To open the case of the PRO-4 you need a Pozidrive or Supadrive screwdriver. Do not use anything else or you will destroy the screw heads. Ensure that the PRO-4 is disconnected from the mains power before opening the case, which we recommend is performed by a competent engineer. On the right hand side, undo the two bottom screws, ignore the top one.

On the left hand side undo the two bottom screws, there are no others.
On the top undo the 3 screws near the front, there are no others.
On the back undo the screw between Channel D and Auxilliary output 1,
Undo the screw immediately to the left of the text which reads "No user servicable parts inside etc."

Do not undo any other screws. You should have removed 9 screws only. When you remove the lid, the earth strap will still be attached, you do not need to remove this. The voltage jumpers are beneath a protective cover just behind the mains transformer. Remove the two screws securing the protective cover, be careful not to lose the nylon spacers. The positions for the jumpers are clearly marked. Set each jumper in the correct position for the voltage you require. Please note the mains fuse should have a lower value for units running from 220/240 volts - this is marked next to the fuse. If your mains line voltage is 230 volts, use the 240 volt setting. When replacing the jumper protective cover, do not overtighten the screws as they are only screwed into the printed circuit board. To replace the lid, reverse the disassembly procedure.

Q: What's the difference between the MIDI retro-fit and the MIDI-DCB converter for the Juno 60?

A: With the DCB box, you get an external unit which is substantially cheaper than a retro-fit. It allows you to send and receive MIDI notes. It has an output so you can clock the arpeggiator and another output so you can control the filter cutoff. The retrofit allows you to send and receive notes, to clock the arpeggiator and to control filter cutoff. You may also control pitchbend, mod wheel, hold, program change and MIDI volume. Plus you have no trailing unit, it's all in the Juno case

Q. When running my TR-808 from Sync24, I find that it runs at the wrong speed. How do I resolve this problem?

A: For the TR-808 to run correctly from MIDI sync, you will need to use PRE-SCALE setting number 3 (quarter notes). TO SET PRE-SCALE - set pre-scale switch to 3 - set to pattern write 1st part - select pattern you want to change - press start button - press clear / pre-scale button until change is heard - press stop - reset to pattern play - done.

Q. I have a Kenton PRO-2 MIDI-CV converter, and would like to add on a DCB or KADI port. Is this possible?

A: No, these modifications are not available for the PRO-2, only for the PRO-2000. The only upgrade available for the PRO-2 is a single channel Hz module which provides Hz/V capability on channel A (if it wasn't fitted originally).

Q. I'm considering purchasing a Kenton PRO-SOLO to control a Roland SH-101. Does the SOLO convert MIDI sync to the clock input used by the SH-101?

A1: For the Pro-Solo mkII. Yes (and it can do this at the same time as CV conversion)

A2: For the Pro-Solo mk1. Yes, but not at the same time as CV/Gate - the Pro-Solo mk1 cannot do both simultaneously. Having said that, you can't use both on the SH-101 anyway, as the CV/Gate inputs override the synth's internal sequencer.

Q. When I try to save the system parameters on my Kenton PRO-4 to 'System Data', they do not store. However, if I save to 'Memory # x' they do store. Is my PRO-4 working correctly?

A: Yes. Saving to 'System Data' only saves parameters such as the display viewing angle, and anything else that says 'System' in the top left hand corner of the LCD - these do not change with the programs. All other parameters should be stored in memories 1 to 8.

Q. What parameters will a Kenton MIDI-CV converter allow me to control on my synth?

A: If you are using just CV and Gate, then you can control notes and pitchbend, plus all Kenton converters have hold and portamento. In addition, they come equipped with built-in LFOs which can be used to modulate the pitch.

Other functions may be controlled on the synth, depending on what additional inputs you have besides CV and Gate. Many synths have a VCF input for controlling filter cut-off, and some, such as the Minimoog, also have a VCA (volume) input.

Synths such as the Korg MS-10 and MS-20 have even more inputs to control effects such as pulse width. In many cases, Kenton can supply Socket upgrades which add extra inputs (eg: filter and modulation for the SH-101).

Q. Will the s-trig input allow a minimoog to play with the glide from its own keyboard?

A: The issue with the glide is due to the way the MiniMoog is designed. The CV (Osc) input is *after* the glide circuit, so it has no effect on the incoming CV/Gate (s-trig) signals. The Pro-Solo MkII has glide built into the converter so that you can use glide, and activate it over MIDI (or auto portamento if enabled). Obviously the glide rate is then controlled from the Solo - not from the knob on the front panel of the MiniMoog.

Midistream FAQs

Q: Why does MidiStream not use Bluetooth?

A: We started out developing both UHF and Bluetooth systems, but abandoned Bluetooth because of latency problems. As Bluetooth is a packet system, the packets have to be filled and notes can become noticably delayed, even with padding. There were other problems too but the latency issue was the overriding one. The UHF system that MidiStream uses gives almost zero latency.

Q: Does MidiStream send all MIDI channels?

A: MidiStream sends all MIDI channels plus SysEx and MIDI clock. In fact it transmits all MIDI messages. Just think of it as replacing a MIDI cable. What you put into the MIDI IN of the transmitter, you will get out of the MIDI OUT of the receiver.

Q: Does MidiStream handle SysEx?

A: Yes, MidiStream handles SysEx; it handles all MIDI messages - see the question above, does MidiStream send all MIDI channels?

Q: I've heard latency mentioned, will I hear a delay?

A: MidiStream has a latency figure of around 2 milliseconds. That is 2 thousandths of a second. This is imperceptible to the human ear. EVERY piece of equipment has SOME latency, however small.

Q: Will it work with my WX-5, windcontrollers send a lot of data?

A: MidiStream has a very high data throughput. You will not have any problems using MidiStream with a wind controller.

Q: How much will it cost to send to the USA?

A: Take this link for a full breakdown of the costs for shipping MidiStream units to the USA.

Control Freak FAQs

Q: How do I reset my Control Freak to its default settings?

A: Turn the unit off. Hold down the four buttons directly above the data wheel (shift, store, edit, edit) while you turn the power back on. When the display says "updating memory", you can then release the buttons. Note that this will reset all the profiles back to their factory default settings also.

Q: I have downloaded the profiles from your website, but how do I get them into my Control Freak?

A: The easiest way is to use the Virtual Control Freak editor for PC which is available for free download from our website. There are now also MAC versions for OS9 and OSX.

Q: When I try to load profiles into the Control Freak, I get the message "Unexpected EOX". What does this mean?

A: This usually means that the profiles have become corrupted, either during download or by the application you are using to load them. Try downloading the website profiles again, and make sure that there are no SysEx filters enabled in the loading application.

Q: When I run the Virtual Control Freak Editor software I get the message: Run-time error '35603' Invalid key. Why?

A: Error 35603. This problem seems to originate when the Windows environment is not in English. It is not known to occur on Windows NT systems. If this happens in your computer, try to do the following:

  1. Click on the "Start" button in the task bar. Choose "Settings", and then choose "Control Panel".
  2. Double click "Regional Settings".
  3. A window should appear with a map in it, and above the map there should be a box with your current regional setting (e.g. French). Change it to "English" (there are several English options, choose any one of them). Changing the above option will not affect any capablities concerning your language. It will only change some settings which Windows uses (for example, the default currency). All the settings which will be affected are listed in the other windows of the "Regional Settings" (above the box with your regional setting, there are tabs which you can use to set certain settings). You may play with some of these settings afterwards (for example, the default measurement system can always be changed between "Metric" and "U.S").

Q: Can I use profiles for the Freak 8 on the Freak Studio Edition?

A: Yes. Profiles for the Freak (8-slider version) as found in the download section may be used with the Freak Studio Edition (16-slider version).

Note that if you want to load 8 channel freak profiles, you can do this but you have to set device number (in global edit) to "8 channel freak" and store that setting. Then 16 slider freak will accept 8 chan profiles and put the even numbered profiles 0,2,4 etc. in the left 8 sliders and the odd 1,3,5 etc. in the right 8 sliders. You can now remap the incoming profiles to directly put them where you want them to go.

You have to have the LCD showing the location for remap to be active.

Q. What can the Kenton Freak do that the Peavey PC1600X can't?

A: The Control Freak is easier to edit.

A: The Control Freak has a free PC editing program to simplify editing even more - download from www.vcontrol.co.uk.

A: The Control Freak can send multiple messages from the same slider or button - of different types, on different channels and even inverted if required, so up is down.

A: The Control Freak can utilise the data from two or more sliders in one message. For example a button can be set up so it sends a note on/off messages taking the note number from one slider and velocity from another.

A: The Control Freak has a built-in MIDI clock generator.

A: The Control Freak has 4 (x2 with the shift key) programmable function keys in addition to the 8 or 16 buttons.

A: The Control Freak has 512k of memory space.

A: The Control Freak has 14 more setups.

Q. Where is the "Sysex load mode" in the Freak Studio Edition menus?

A. You don't need it any more - the 16 slider version is always ready to receive sysex.

Q. How do I know if my MIDI equipment is compatible with a Control Freak?

A. The Control Freak is 'compatible' with any piece of MIDI equipment that is capable of external MIDI control! It is a common misconception that the Freak will only work with equipment for which there are profiles, or with programs which 'support' the Freak. The degree to which a piece of equipment may be controlled depends largely on its MIDI implementation.

For a list of pre-programmed profiles, please visit the download section of our website.

Retrofit FAQs

Q: How do I know if I have the 32 prog or the 120 prog OB-Xa?

A: The dead giveaway is that the 120 program version usually has a big badge on it, on the right side of the top panel saying 120 programs, so if you aren't sure, you've probably got the 32 program model.

However to be sure, try the following test as some earlier models have been updated to handle 120 progs or the badge might have fallen off.

To access more progs on the 120 version, it also allows you to press combinations of the A B C D buttons. (and the multiple leds stay lit)

On 32 prog model you can only select either A or B or C or D - ie A1, B1 etc.

On 120 prog model you can also select AB1 AC1 ABC1 ABCD1 etc etc. You have to press the letter keys at the same time as each other. You must press the number key afterwards.

So try pressing A & B at the same time and see if the A and B leds both stay lit. If they do, it's a 120 version. (or it just crashed)

Q: How can I tell what revision my Prophet 5 synth is?

A: Refer to the list of serial numbers below:

SERIAL # REVISION #
0001-0182
0184-1299
1300-2285
2286-2423
2424-2451
2452-2455
2456
2457-2465
2466
2467-2476

3.0
3,1
3.0
3,2
3.0
3,2
3.0

The only difference between rev 3.2 and 3.3 is the number of programs. If yours has 120 programs, then it is effectively rev 3.3

Q: What's the difference between the MIDI retro-fit and the MIDI-DCB converter for the Juno 60?

A: With the DCB box, you get an external unit which is substantially cheaper than a retro-fit. It allows you to send and receive MIDI notes. It has an output so you can clock the arpeggiator and another output so you can control the filter cutoff.

The retrofit allows you to send and receive notes, to clock the arpeggiator and to control filter cutoff. You may also control pitchbend, mod wheel, hold, program change and MIDI volume. Plus you have no trailing unit, it's all in the Juno case.

Q. What is the difference between a 'Self-Install MIDI kit' and 'Factory Fitted MIDI'?

A. A self-install MIDI kit comprises all the parts and circuit boards (ready assembled and tested) for a full internal retrofit. It requires fitting by a competent service engineer (ie: someone who is capable of repairing the synth).

Factory fitted MIDI is installed by our own engineers here at Kenton Electronics. This service is usually only available to U.K. customers, as the synth needs to be delivered to our premises.

Q. Why do your synth retrofits appear to be so expensive?

A. We find that customers who ask us this are comparing our kits with, say, soundcards manufactured in the Far East in great quantities using cheap labour and with guaranteed large volume sales.

Our retrofits cover an extensive range of models, each of which has been researched and custom designed for that model and which provide features unavailable elsewhere.

It is not unusual for us to sell only one or two of a model a year, thus preventing economies of scale to bring the price down. All retrofits are exhaustively tested and monitored over a prolonged period prior to despatch.

We feel that, all things considered, our retrofits do represent good value for money.
