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.

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 are 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 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


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

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-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?

A: Yes, but not at the same time as CV/Gate - the PRO-SOLO cannot do both simultaneously. Having said that, you can't use both on the SH-101 anyway, as the CV/Gate 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).
