Description:

The S-2000 is not merely a new repackaging of old designs. It is a revolution, and a game changer. Metasoni does not make

“clones” of “vintage” gear, so you will find the S-2000 to be completely different from any other musical instrument you have

ever used. It is capable of simulating some classic “vintage” synthesizer sounds, but because of the numerous quirks of

vacuum-tube electronics, it is able to do very much more than that.

Unlike ordinary analog synths, the S-2000 has an all-tube signal path. It is a basic yet fle ible path: Operator 1, which can be

used as a bandpass filter but is more likely to be used as a voltage-controlled oscillator, feeds directly into Operator 2, which

is an identical circuit. Its output goes into the VCA, where an envelope is imposed on the signal.

All the controls to the left of Operator 1 are the CV effect controls. The S-2000 has three “contour” or envelope generators: C1

controls the VCA envelope, and has rise and fall (attack/release) controls. C2 and C3 are transient, or “attack/decay”

envelopes. They can be used as LFOs by activating their REPEAT switches. The speed of the repetition is controlled by both the

rise and fall knobs, so they are used as LFOs with variable duty cycle. The built-in ribbon controller is a standard

SpectraSymbol 400mm industrial position sensor, requiring only a very light touch to activate.

There are three LED indicators on the panel. The VCA tube lights up when C1 is triggered, and the lamps ne t to the controls

for C2 and C3 show their operation. Power is indicated by the tubes themselves, they have hot cathodes that give a slight

orange glow. (Note: it may be difficult to see, especially in bright light. Do NOT assume a tube has gone bad just because you

can't see the hot cathodes.)

Please don't be intimidated by the numerous knobs and switches. They are all there for good reasons, and will

make sense as we go along.

Controls and interfaces:

The S-2000 panel is divided roughly in half, with the CV controls on the left and the audio path controls on the right. First we

start with the audio section.

The path is very simple: operator one feeds directly into operator two, which feeds directly into the VCA.

The secret of the S-2000's fle ibility is in the controls for the operators. A basic setting for the controls, seen above, will be

the starting point.

What the operators do is highly dependent on the RESONANCE controls, so their settings are important.

TUNE controls are self-evident, they are usually set to 12 o'clock for most uses.

DRIVE controls the amount of drive level into the ne t stage; they interact with each other and affect the filter effects and

distortion somewhat.

AUDIO MAIN LEVEL is self-e planatory, and the switch ne t to the output jack determines the mode of the VCA envelope. Set

it down to use only the C1 contour to control the envelope, set it up so that C1 is mi ed with C2, making an ADSR envelope

effect.

The CV section controls the audio section, but is independent of it. The three “contour” generators are basic attack-release

(C1) or attack-decay (C2 and C3) types, which trigger when the ribbon is pressed. A sample-and-hold “freezes” the pitch CV

made by the ribbon when it is released, if CONTROLLER FUNCTION is set to the left. This allows the pitch to be constantly

varied by dragging your finger (or a stylus) up and down the ribbon. If CONTROLLER FUNCTION is set to the right, the

sample-and-hold opens only briefly upon first ribbon pressure, so the pitch is kept so long as the ribbon is held down, but

remains the same even if your finger is moved up and down the ribbon.

The REPEAT switches, when set to the right, turn C2 and C3 into low-frequency oscillators (LFOs). The speed is controlled by

both the rise and fall knobs, allowing for a slow rise and fast drop, or vice versa, or even audio-level signals if both are turned

down.

To begin:

First, set all the CONTOUR controls fully DOWN, counterclockwise. Set the switches for them as shown above. Set the audio

controls as shown on the previous page, and note that RESONANCE control settings will vary with individual S-2000s and their

installed tubes. So you might have to adjust the RESONANCE knobs from the settings shown, to get best results.

Plug in the AC power adapter. The one included (if any) is a “universal” type, and will just need added plug adapters to allow

its use anywhere on earth. The power inlet for the S-2000 is a 2.1mm coa ial jack, center positive. The S-2000 needs 12 volts

DC (not AC!), as clean as possible, at 1.5 amps for initial power-up, and 600 mA thereafter. If you need to replace the power

supply, any type capable of 12 volts DC at 1.5 amps minimum will work.

Connect the output to an amplifier or mi er, so you can listen to the S-2000. Press the ribbon somewhere at the bottom; you

should hear the pitch of Operator 1. Moving your finger up and down the ribbon should change the pitch. (If you hear no

pitch, adjust RESONANCE on Operator 1 until you do.)

Now try adjusting Operator 2's RESONANCE, to hear its filtering effect. Once you get the optimum filter sound, adjusting TUNE

on Operator 2 will give the classic synthesizer “wooooow” effect. Turn up the C2 CV LEVEL knob, so the C2 contour varies the

filter tuning; then adjust C2's rise and fall controls to hear the filter being swept automatically. Now it's a synthesizer!

Note that you will hear a click when pressing or releasing the ribbon. This is typical of pentode tube VCAs, and is NOT a

defect. If it bothers you, adjust C1's rise and fall controls slightly to minimize it. Also note that releasing the ribbon can have

an effect on the pitch when C1's fall control is turned up: this is an odd imperfection of the ribbon controller, and is normal.

Adjust C1 fall for the best desired effect.

Suggestions for use:

Inputs and outputs:

The main audio output is a 1/4” (6.3mm) standard phone jack. Output impedance is 1000 ohms and will drive a 600-ohm load

easily. (It will NOT drive most headphones or a loudspeaker directly.)

CV and gate outputs from the ribbon are accessible from the 1/8” (3.5mm) front-panel jacks at all times. The CV varies from

1.5v to 7v, and the gate is 0-10v.

The CV and gate inputs (1/8” (3.5mm)) can be used by switching the CV/gate selector switch. The main CV affects both

operators simultaneously, and can be varied from 1.5v to 10v for more than 3 octaves of pitch/filter range, also tunable with

the front-panel tuning knobs. The ma imum pitch range of the two operators is from less than 10 Hz to more than 3 kHz. The

Gate input requires 0-10v DC voltage to fully open the VCA. Note that it only affects C1, and does not trigger C2 or C3.

The audio input feeds into operator one, so that both operators can be used as bandpass filters in series. Or, the resonance on

either one can be decreased so that it passes the signal, so only one operator is used as a filter. Plugging an output into this

jack will change the resonant behaviour of Operator 1, so if its use as a pure VCO is desired, leave this input unconnected to

e ternal gear.

If you wish to hit certain pitches easily, we recommend marking the locations on the ribbon using a permanent marking pen,

and then playing the ribbon with a stylus (a ballpoint pen with the cap left on is perfect). This will allow the careful musician to

play in tune with other instruments, while still having the freedom of pitch bends, small or massive. Be careful not to change

the tuning of Operator 1 so your scale is not upset.

By setting Operator 1 to oscillate and Operator 2 to also oscillate, and detuning them, some primitive FM and sync sound

effects can be realized. This is unknown territory, especially if C2 and C3 are used as audio oscillators to inject more signals

into the operators. All of these effects will cross-modulate and interfere with each other, in ways that are difficult to predict

and impossible to emulate with solid-state electronics, allowing for massive areas of new sound effects for e perimentation.

Technical:

The vacuum tubes in this version of the S-2000 are two 6GH8/6U8s and one 12AW6. Despite not being made anymore, they

are among the most commonplace NOS tubes in the world, and are easy to find. They are run VERY conservatively in the

S-2000, and will be e pected to last many tens of thousands of hours, so stop worrying about “constantly” replacing them. If

you require a set of replacement tubes and can't find them locally or online, contact a Metasoni dealer for spares.

“Tube rolling”, trying different tube types in the sockets to see if they sound different, is NOT recommended. The VCA tube can

be replaced with several types of pentodes or pentagrid converters having 12v heaters, but you are unlikely to notice much

difference in sound anyway.

Note that a 5-volt “TTL-level” gate signal is NOT enough to gate the S-2000's output. You will need 10v to open it.

The connector for the ribbon will accept any of the SpectraSymbol “Softpot” series of ribbon position sensors. They all have

the same pinout. Softpots come in lengths from 25mm to 1000mm (one meter). By making up a suitable cable and mounting

base for the 1-meter Softpot, it will give ma imum resolution of pitch control. (Note: this is an advanced modification and

should only be attempted by e perienced technical personnel.) Any further modification of the S-2000 requires advanced

understanding of the circuit. There are a few changes that are possible, but we normally do not recommend them.
