Introduction In the beginning, there was the knob… And the knob was good. Great, in fact. You could just reach out and grab it. Turn it left. And turn it right. Interact with it in realtime. And there were knobs of all kinds. Knobs for changing the attack and release times of a sound. Knobs for setting the cutoff filter and resonance. And knobs for controlling many other aspects of analog synthesizer sounds.
perform and listen to music. Global design standards ensured that music hardware and software products made by different manufacturers could work together seamlessly. But alas, digital did not create a perfect world. on the panel. A collection of six rotary Sound Control Knobs are irresistible to the touch—and provide instant sonic results when turned. Between the Sound Control Knobs, the clearly labeled panel switches, and the back lit LCD, the current status of the CS1x is always crystal clear.
CS1x MAIN FEATURES The CS1x is specially designed with an intuitive, interactive user interface through lots of dedicated panel controls and sound editing features which can easily be manipulated in realtime during performance. Main features include: • 6 Sound Control Knobs for direct access to key parameters of the currently selected voice as you play, and 2 Scene memories for instant recall of specified Sound Control Knob positions.

THE CS1x AT A GLANCE MIDI THRU OUT IN Rear Panel ! MIDI MIDI IN, OUT and THRU terminals let you connect other MIDI devices such as a MIDI keyboard, tone generator, sequencer, or computer with a MIDI cable. (Set the HOST SELECT switch to MIDI when using the MIDI terminals.) MIDI IN is for input of MIDI data. MIDI OUT is for output of MIDI data and for data dumps to another CS1x or MIDI data storage device.
GETTING STARTED Setting Up Your CS1x The Control Synthesizer CS1x literally comes ready to play right out of the box. The CS1x With An External Sequencer Connect the supplied PA-3B DC power adaptor to the CS1x's DC IN connector on the rear panel. Then connect the adaptor to the nearest electrical outlet.
Connecting The CS1x To A MIDI Data Storage Device Macintosh If you have an Apple Macintosh not equipped with an external MIDI interface, perform the following operation: You can also connect the CS1x with a MIDI data storage device, such as the Yamaha MDF2 MIDI Data Filer in order to "bulk dump", or save a User Performance ("1 Perf" setting) or all the User Performances and Utility parameters ("All" setting) to floppy disks. 1. Set the HOST SELECT switch to Mac. 2.
Switching On The Power And Producing Sound Playing Arpeggiated Chords Take a moment and try out the Arpeggiator function, which creates automatic arpeggios based on the chords you play. First select a Performance with a fast attack, such as a percussive type sound. (Note: The Arpeggiator function only works in Performance mode.) Once all connections have been properly made, you're ready to switch on the power and start having fun with the CS1x. 1. Turn the volume of the CS1x to its minimum position. 1.
How The CS1x Generates Sound Oscillators, Filters And Amplifiers In order to better understand what's actually happening to the sound as you turn the Sound Control Knobs or modify other parameters, it is helpful to first take a look at the key components which make up the physical nature of sound. Synthesizers rely on three key electronic components to imitate the soundwaves of musical instrument voices, as well as create entirely new sounds.
CS1x Synthesis The secret behind the CS1x's exceptional quality sound is its ability to create rich and complex sonic textures in Performances, which are made up of Layers of up to four AWM2 voices—either sounding simultaneously or mapped to various note and velocity zones across the keyboard.
CS1x MAIN OPERATING MODES The CS1x has two main operating modes: Performance mode and Multi Play mode. The chief distinction between each mode is as follows: AMP EG VOLUME • Performance mode is primarily for realtime performance of Layers. It has six menus of Edit parameters. ATTACK RELEASE ASSIGN 1/DATA CUTOFF RESONANCE ASSIGN 2 2 MW/FC 1 FILTER • Multi Play mode is primarily for multitimbral playback of up to 16 Parts when external MIDI devices are connected. It has one menu of Edit parameters.
Basic Basic Operations In Operations In Performance Performance Mode Mode PERFORMANCE PLAY next to the Performance number, to indicate that the edited sound has not been stored. Performance Play mode lets you select a Preset or User Performance for realtime play. • Offset AMP EG and FILTER parameters to change the shape and tone of the sound as you play by turning the Sound Control Knobs. • Press the PERFORMANCE button to enter Performance mode (if you're in a different mode).
Performance Structure Storing User Performances Storing your own User Performance is a quick and simple operation. Preset Bank User Bank 128 Performance 128 Performance 007 006 005 004 003 002 001 1.

Following is a description of each function in the various modes. In Performance mode you can choose from 128 Preset and 128 User Performances. A Performance consists of a maximum of four layered sounds (voices). The Performance Edit function lets you easily edit each Layer within a Performance. The various parameters give you the flexibility to create a vast variety of sounds. Entering Performance Mode ● Selecting a Performance Press the PERFORMANCE button.
● Edit Procedure Quick Program Change Press the QUICK PC (Quick Program Change) button in the numeric keypad to fix all the numbers except the first digit of the Performance number in the LCD. By pressing a button in the numeric keypad (0~9), you can quickly select the Performance numbers within a group of ten by changing the first digit of the Performance number. The hundredth and tenth digits will be shown as bold characters to indicate they are fixed.
NOTE You can also use the numeric keypad (0~9) or the Data Entry knob to change the value. NOTE To exit Performance Edit mode, press the PERFORMANCE button again or the PROGRAM [-]/[+] button. You can enter Multi Play mode directly from Performance mode by pressing the MULTI button. NOTE To change the value for all four Layers at one time, hold SHIFT and press the Parameter Value UP/DOWN button.
■ PERFORM LEVEL To start the Arpeggiator, press the ARPEGGIATOR button to turn it on. A [▼ ] mark will appear in the LCD above the word "ARPEGGIATOR". NOTE This sets the volume of each Performance. To turn the Arpeggiator off, press the ARPEGGIATOR button again. TYPE: Sets the type of arpeggio. You can choose from 30 types. For details about each type, see the Arpeggiator Type List in the "Data List" book.
■ PERFORM NAME (Performance Name) NOTE If you select EFFECT OFF in the Variation Type menu, the layers which have the VARI SEND function set to ON will not sound. When you don't want to use the Variation Effect on the layers, set VARI TYPE to Thru. This lets you select the Category and name the User Performances using up to eight letters, numbers, symbols and characters. 1. Use the Parameter Value UP/DOWN button to move the cursor to the position at which you want to enter a character.
Common Edit 2 (applied to all Layers) ■ MW (Modulation Wheel) This row provides functions and parameters which are common to all Layers in a Performance (except for "Portament"), including the settings for realtime controllers such as the Pitch Wheel, Modulation Wheel and Foot Controller. This sets the control parameters of the Modulation Wheel. There are three parameters: PMOD (Pitch Modulation), FMOD (Filter Modulation) and CUTOFF (Cutoff).
■ FC (Foot Control) ■ PORTA (Portamento) This sets the parameters controlled by a Foot Controller connected to the FOOT CONTROLLER jack on the rear panel. There are three parameters: FMOD (Filter Modulation), CUTOFF, and VARI EF (Variation Effect). This sets the Portamento function. Portamento continuously changes the pitch from one note to the next, thus letting you glide the pitch from one note to the next. There are two parameters, SWITCH and TIME. Values can be set for each Layer.

It is possible to assign up to four parameters from 28 types. It is also possible to set the sensitivity (control range of the knob) for each parameter. The parameter assigned to the ASSIGN2 knob as the default differs depending on the Performance selected. 1. Select the Layer.
Layer Edit 2 (independently applied to each Layer) VOLUME The functions in this row provide parameters which are essential in creating a voice, such as AEG (Amplitude Envelope Generator) and LFO (Low Frequency Oscillator). The parameters can be set for each Layer in a Performance.
FMOD (Filter Modulation): Adds a cyclical change to the filter cutoff frequency by applying LFO frequency modulations, to create wah-wah type effects. Larger values widen the range of cutoff frequency change. Settings: AMOD (Amplitude Modulation): -31 ~ +31 PMOD (Pitch Modulation): -63 ~ +63 FMOD (Filter Modulation): -15 ~ +15 WAVE: Saw, Tri , S&HTr, Elem SPEED: -63 ~ +63 PHASE INIT: Free, Retr, Elem WAVE: Selects the LFO frequency signal used for modulation.
Attack Time ■ PEG (Pitch Envelope Generator) Decay Time This sets the PEG (Pitch Envelope Generator). The PEG lets you shape how the pitch of the voice changes over time, from when a key is hit, then released, and how the sound decays. There are six parameters: INIT LEVEL (Initial Level), ATK TIME (Attack Time), ATK LEVEL (Attack Level), DCY TIME (Decay Time), REL TIME (Release Time) and REL LEVEL (Release Level).

■ PAN NOTE The value of some Layers may forcibly be changed when using the Variation effect. This sets the panning (the left or right position in the stereo spectrum) of each Layer. Different pannings can be set for each Layer, thus providing for a richly textured stereo image (for stereo output). NOTE For more information, see page 47. ■ FILTER This sets the filter parameters for each Layer. There are two parameters, CUTOFF and REZ (Resonance).
■ POLY/MONO ■ Tips About Performance Mode This determines whether the voice in each Layer is played monophonically (only one note at a time) or polyphonically (up to 32 notes at a time). • In Performance Mode, you can use a Performance (voice) and 12 Parts (Part 5~16) for Multi. Though the receive channels are set in the factory as shown in the illustration, you can change the receive channels using RCV CH (Receive Channel) in Utility Mode.
In Multi Play mode you can play up to 16 Parts using an external MIDI sequencer. This mode is mainly used when the CS1x is used as an XG-compatible tone generator or as a data input device in a computer music system. You can use any XG voice from the 480 normal voices and 11 drum voices. When playing back from or recording to an external sequencer, you can use the Multi Part Edit function to edit the volume and effect of each Part. External MIDI Sequencer Editing Procedures PART 1~16 1. Select a Part.
● Description of Each Function NOTE It is also possible to change the Program number quickly by using the Quick Program Change function, the same way as in Performance mode. For details, see page 21. ■ BANK This lets you select a Bank. Various normal voice banks containing up to 128 normal voices, a bank with different drum voices (kits), plus SFX banks are available to choose from.
■ PAN REV SEND (Reverb Send): Determines the send level of the Reverb effect. This sets the panning (the left or right position in the stereo spectrum) for each Part. Different pannings can be set for each Part (for stereo output). CHO SEND (Chorus Send): Determines the send level of the Chorus effect. VARI SEND (Variation Send): Enables or disables the output of the Variation effect.
■ POLY/MONO This determines whether the voice in each Layer is played monophonically (only one note at a time) or polyphonically (up to 32 notes at a time). Generally, Polyphonic mode is selected to generate multiple sounds at one time. There are cases, however,where it is more effective to select Monophonic mode, such as when using a bass sound, brass sound, or an analog synthesizer sound.
In Utility mode you can set the CS1x system and MIDI parameters. CS1x NOTE Other parameters will appear in the LCD when you press the other Parameter Value UP/DOWN buttons. Continue setting the other parameters. CS1x MIDI SYSTEM SETTINGS MIDI SETTINGS MASTER TUNE KBD TRANS VEL CURVE VEL FIX TRANS CH RCV CH DEVICE NO LOCAL BULK DUMP ASSIGN CONTROL CHANGER NUMBER NOTE Press the PERFORMANCE button or the MULTI button to exit Utility mode and return to each respective mode.
■ VEL CURVE (Velocity Curve) Hard: This curve is designed to increase the volume level with a stronger playing style. This is suitable for people with a strong key touch. The velocity curve set here determines the way the CS1x's tone generator responds to playing velocity when the VEL FIX parameter (see below) is set to OFF. The following six types of curves are available: VOLUME Norm (Normal): The velocity is in proportion to the strength (how hard you play the keyboard).
■ RCV CH (Receive Channel) ■ BULK DUMP (Performance Bulk Dump) In Performance Mode, this sets the MIDI receive channel for controlling the CS1x with an external device such as a MIDI sequencer or computer. This lets you send Performance data from the CS1x in bulk to another CS1x or to the Yamaha MIDI Data Filer MDF2. This is convenient for backing up, storing, or managing your important Performance data.
■ ASSIGN CTRL NO (Assign Control Change Number) Assigning the Controllers 1.Move the controller on the panel to which the Control Change Number is to be assigned. The parameters of the controller will appear in the LCD. This lets you assign Control Change Numbers to controllers such as the Modulation Wheel or Sound Control Knobs. This is mainly used to control external devices connected via MIDI. NOTE The main function of the Sound Control Knobs will not be changed.
In Store mode you can store edited Performances or Scenes in the CS1x's internal memory. To enter Store Mode, you must first be in Performance Mode. 3. Press the ENTER/YES button. “Sure?” will appear in the LCD. NOTE You cannot enter Store mode from Multi Play mode or Utility mode.
Selecting a Scene First select the Performance to which you have stored a Scene. Then press the SCENE 1 or SCENE 2 button to select the Scene. The LED by the button will light to indicate that you have activated the Scene settings. 1. Set each Sound Control Knob to your preference. AMP EG ATTACK RELEASE ASSIGN 1/DATA CUTOFF RESONANCE ASSIGN 2 Each Sound Control Knob will be disabled when a Scene is selected, and you will not be able to change the parameters using the knobs.
You can reset all of the settings in the CS1x (Performance, Scene, System and MIDI settings) to the original factory (initial) settings. NOTE Executing this function will replace all of your existing data. As such, always store your important data to an external device such as the Yamaha MIDI Data Filer MDF2 beforehand. Turn the power of the CS1x off, then, while holding the 7, 8, and 9 keys on the numeric keypad, turn the power back on.
The CS1x features three independent digital effects units, Reverb, Chorus and Variation, which can be applied to the voices in a variety of ways to provide a wide range of sound processing capabilities. In Performance mode you can choose the Reverb, Chorus and Variation effect types, as well as set additional parameters for the Variation effect.
