1) Introduction  ^

Congratulations on buying the Korg MS-10 Synthesizer.

This instrument has been engineered and manufactured using the most advanced techniques known today, and features the same unparalleled technology utilized in Korg's revolutionary Polyphonic Synthesizers, the PS-3100 and PS-3300.

With reasonable care, it will provide years of high quality and reliable use with unsurpassed stability, versatility and longevity.

Please read this manual carefully to get the most out of your MS-10.

4) Normal Setting  ^

This diagram illustrates control positions for the Normal Setting. In this setting, all modulation functions are disconnected, producing a basic, unmodulated tone.

This Normal Setting is the foundation on which you will build when creating sounds with the MS-10. You will find it useful to be able to return to this setting whenever you start a new patch. Therefore, it is recommended that you memorize these control positions for greater efficiency of operation.

6) About Patching  ^

Setting up a patch is one way to control the MS-10 more effectively. Patching involves using such outputs as the control wheel in a creative way to control various synthesizer functions. This greatly increases the sounds and effects that are possible.

To get the effect you want, follow these steps:
(1) Where (VCA, VCF, VCO, etc.) do you want the effect and what kind of effect do you want?
(2) What kind of control signal do you need for the effect?
(3) Which section of the synthesizer will generate that kind of control signal?

If you don't put your thoughts into this order before you start connecting patch cords from one jack to another, it is not possible to get the kind of sound you are looking for.

Even if you just use the internal patch without external patch cords, these same rules apply. When you want a certain sound, break it down into its elements of pitch, tone color (timbre), volume, and envelope (volume change over time). Then put these elements together by using the various sections of the synthesizer.

Remember that the keyboard generates both a control voltage and a trigger signal every time you play a key. In other words it acts as a control knob and a switch.
Make maximum use of this and other less obvious possibilities for sound creation. The more techniques you know, the more freely you can make music.

7) Upgrading your system  ^

[asterisk] The SQ-10 Korg Analog Sequencer can easily be used along with the MS-10 for some interesting results.
Here are just two examples. (Refer to the SQ-10 owner's manual for more details.)

(1) One simple idea is to set up the SQ-10 to produce a different pitch and tone color in the MS-10 at each step. Then use the internal clock of the SQ-10 to run through the steps. This results in automatic control of the MS-10.

(2) For performing live, another effective way of using the SQ-10 is to set up a patch so that the SQ-10 advances one step and changes the tone color every time you play a key on the MS-10.

[asterisk] Two MS-10 synthesizers can be used together to increase the richness and depth of the sound.
- connecting two MS-10's

Connect patch cords from the KBD CV OUT and TRIG OUT of the MS-10 on the left to the VCO CV IN and TRIG in of the MS-10 on the right. With this arrangement, both synthesizers operate together when you play the keyboard of the one on the left. But if you try to play the right hand keyboard, nothing will happen because it has been disconnected by the patch cords in the VCO CV IN and TRIG IN input jacks. So decide which keyboard you are going to use before you set up the patch.

Using separate amps (or left and right stereo channels) for each synthesizer gives a better effect.

You can also try setting all the controls at the same positions for both synthesizers and then varying the pitch slightly on one of them. This can produce a phase effect or jet effect. This can be effectively used both on the stage and in the recording studio for multi-track recording.

[asterisk] There are many ways of using other equipment with the MS-10. But the simplest way of upgrading your system is to use a lot of patch cords. It's also the cheapest. So stock up with plenty of Korg Patch Cords. The teachings of Doctor Korg remind us to consider what we want and how to go about getting it before plugging patch cords into every hole we see. But if you run out of jacks you can always buy or make a junction box.

8) Caution  ^

(1) On the MS-10 front panel are five small rubber plugs which cover internal adjustment trimmer controls. Do not change these control settings. They have been adjusted at the factory to give optimum results. Changing their setting will result in performance deterioration, and possible harm to the instrument.

(2) Pay attention to the voltage indications (0~+5V, -5V~+5V, 5Vpp, etc.) in the patch panel and their relationship with the block diagram and signal flow chart. The patch panel itself is arranged in a flow chart to make things simpler.

Note that if you connect a -5V~+5V control signal to a 0~+5V input, nothing will happen during the -5V~0V portion of the control signal. It will only operate from 0~+5V. So always consider both the output and the input and whether the signal is analog or digital, the latter represented by [ground].
