KENTON PS-3100 MIDI Retrofit Kits

Product Information

Specifications

• Product: Kenton MIDI Retrofit for KORG PS-3100 / PS-3200 / PS-3300
• Firmware Requirement: PS3x5113 or later
• Compatibility: Korg PS3x MIDI retrofit kits produced after 21st December 2006
• Connector Type: 3.5mm mono jack cables

Product Usage Instructions

Using the MIDI Interface

1. After installation, the synthesizer defaults to omni-off mode channel 1 for MIDI receive.
2.  To change the receive channel, select it and it will be stored in memory for future use.
3. To reset to factory default settings, turn on the synth while holding the red push button pressed for a couple of seconds.

Red Push Button

• Two modes available by pushing the red button during normal playing mode.
• Use a remote MIDI keyboard connected directly to the MIDI IN socket of the Korg PS3x for key presses detailed below.

Assigning MIDI Control Sources to Destinations

Various controller sources can be assigned to destinations using specific keys on the remote MIDI keyboard.

Connecting External Controllers

Use 3.5mm to 3.5mm mono jack cables to connect external controllers to the jack sockets on the back of the synth.

User instructions

These instructions are only for Korg PS3x MIDI retrofit kits produced after 21st December 2006 with firmware PS3x5113 or later.

N.B. Different instructions apply to earlier Kenton PS3x MIDI retrofit kits.

USING THE MIDI INTERFACE

When you turn on the synthesizer for the first time after installation, you will be in omni-off mode channel 1 for MIDI receive. See the following pages for other factory default settings. When you select a receive channel, this will be stored in memory and will be remembered for when you subsequently turn on the synth – all parameters listed on the next page are stored.
If you want to put the machine back to the factory default settings at any time, switch the synth on whilst holding the red push button pressed – hold for a couple of seconds then release.
MIDI Note messages received, will be played by the synth as if played on its own keyboard, notes are internally hard-wired. Other MIDI commands such as pitchbend and modulation are routed to jack sockets mounted in a box on the back of the synth. These can be patched as required to the various inputs on the front of the synth. You need 3.5mm to 3.5mm mono jack cables for this purpose.

RED PUSH BUTTON

Two modes are available by pushing the red push button during normal playing mode. Before you press the red button however, make sure that no keys are pressed on the remote MIDI keyboard otherwise the results may be unpredictable. The key presses detailed below should be entered on a remote MIDI keyboard connected directly to the MIDI IN socket of the Korg PS3x (not via a computer or patch bay).

1. SET-UP MODE
   For setting MIDI channels and assignments. Give the red push button a short press (half a second) – then release. Follow this with a key or sequence of keys on the remote MIDI keyboard as detailed on page 2. After making a MIDI channel assignment, you will be automatically returned to playing mode but after making other assignments you will need to press the ENTER key (Top C) to return to playing mode. This is to enable you to make the multiple key presses required when re-assigning Sources to Destinations. (N.B. all set-ups are stored in non volatile memory).

2. TRANSPOSE MODE
   Press and hold the red push button for about four seconds – then release. Middle C will sound on the synth and continue to sound until you press a key. The key that you press on the remote keyboard will be the new middle C for MIDI IN. You can set any value up to two octaves up or down – settings outside this range will be ignored (where middle C = no transposition) . Note that transpose mode cannot be entered from set-up mode. (N.B. the transposition will be stored in non volatile memory).

The bottom four octaves on a 61 note remote keyboard are used to set “transpose” – with middle C being the transpose OFF point.

Function of keys during set-up mode

ASSIGNING MIDI CONTROL SOURCES TO DESTINATIONS

SOURCE

Pitch-bend wheel
Modulation wheel (cc#1)
Aftertouch
Velocity
Controller X (def cc#16)
Controller Y (def cc#17)
MIDI Volume (cc#7)

DEFAULT DESTINATION (back panel box)

Pitch-bend output jack
Modulation output jack
Aftertouch output jack
—-
Filter output jack
Res output jack
Volume output jack

1. To assign sources to destinations,
2. a) press the red push button to enter set-up mode (one short press)
3. b) select a source by using one of the keys A to Eb (see table on previous page)
4. c) [optionally if the source is Controller X or Y, you can assign a controller to it now – see below]
5. d) select destinations OFF to de-select previous assignments for this source
6. e) select destinations ON to make new assignments for this source
7. f) either hit Top C to enter/exit, or select a new source and make assignments for that [go back to b]
8. Controllers X & Y can be assigned to any continuous controller (cc). By default controller X is assigned to cc#16, and controller Y is assigned to cc#17. To re-assign either of them, first press the red push button twice to enter SET-UP mode. Next press the Db or D key (see table on previous page) to select the X or Y controller source, then send a MIDI message of the required continuous controller. Then either press top C to enter / exit, or use some of the destination keys to assign what this controller will control.
9. – For example to set controller Y to respond to cc#4, press the red button twice, press D, send a cc#4 message to the Korg PS3x from another synth or MIDI controller, then press top C to enter /exit. [or select another function]
10. Sources can have multiple destinations, so for example controller X could be assigned to control both filter and volume at the same time, should you want it to.
11. Where the pitch-bend wheel is the source, only the bend wheel UP will affect destinations other than pitch-bend. Also where pitch-bend is the destination, sources other than pitch-bend wheel will only bend the pitch UP.
12. Receive channel setting will return you directly to playing mode, all other keys will let you stay in SET-UP mode until you press the ENTER key (Top C).
13. The ENTER key (Top C) also performs a “reset all controllers” function – OFF in most cases, but ON for volume, and centre for pitch bender.
14. If you want to put the MIDI back to the default settings at any time, switch the synth on whilst holding the red push button pressed – hold for a couple of seconds then release.
15. During set-up mode, the retrofit will receive on ALL MIDI channels.
16. List of continuous controllers (cc) recognized – (numbers in decimal)
17. List of other commands recognized – (numbers in hexadecimal)
18. Program change – you can enable or disable response to incoming program change messages by using the Eb and E keys (see list on page 2)

CONNECTING PATCH CABLES

To control pitchbend: (use pitchbend output of MIDI)
Patch into TOTAL FREQ input (bottom left of panel)
Set RH orange switch for section to ONSet EXT TOTAL MOD INTENSITY knob to approximately 2 for 2 semitones up & down

To control modulation: (use mod output of MIDI)
Set MODULATION BALANCE knob to MG1
Set MG1 OR S/H MODULATION INTENSITY knob to 6
Patch into VCA CONTROL jack (8th along bottom and 1 up)

To control filter: (use cont16 output of MIDI)
Patch into CUTOFF FREQUENCY jack (7th along bottom)
Set RH orange switch for section to ON
Set EXT MODULATION INTENSITY knob to approximately 8

To control volume: (use cont7 output of MIDI)
Patch into VCA 1 CONTROL jack (17th along bottom and 1 up)

GENERAL INFORMATION ABOUT MIDI CONNECTIONS

Any MIDI IN should be connected to a MIDI OUT or a MIDI THRU similarly any MIDI OUT should be connected only to a MIDI IN and any MIDI THRU should also only be connected to a MIDI IN.

MIDI OUT is the signal from the synthesizer (or drum machine etc.) that is to be sent to another instrument. MIDI IN is a received signal that contains MIDI information from another synth, and MIDI THRU is an exact copy of information arriving at the MIDI IN socket. This allows several instruments to be connected together.

If you want to wire your own MIDI cables the following information may be useful.

1. Although a 5 pin connector is used, only two connections plus an earth connection are required.
2. If you look at the din plug from the wiring side you will see that the pins are numbered. From left to right (or clockwise) these are 1 – 4 – 2 – 5 – 3.
3. The pins numbered 1 & 3 are not used.
4. The screen (earth) is connected to pin 2 (centre pin)
5. Pin 4 of one plug should be connected to pin 4 of the other
6. Pin 5 of one plug should be connected to pin 5 of the other
7. You should now have a working MIDI lead
8. It is preferable to label one end of the cable MIDI IN & the other end MIDI OUT, to avoid confusion.
