The S1 is a semi-modular, analogue monophonic synthesizer. It is easy to get started with since it is pre-
patched for optimal use of its sound producing possibilities and eliminates the need for external connections
between modules during use. Each module can be disconnected and used separately, e.g. to control or be
controlled by other instruments. This flexibility enables and simplifies experimentation with creation and
reproduction of sound.
We can mention some important features of the S1:
* Three oscillators with seven basic waveforms
* Ring modulator
* Noise generator with two three noise shapes
* Low pass filter with selectable 4 / 6 poles and quasi band pass mode
* Multi mode filter with selectable 2 to 6 poles and three modes
* Wide range envelope generators
* Master amplifier with build-in overdrive stage
* LFO with seven basic waveforms and wide rate range
* Extensive modulation of, virtually, all synthesis parameters
* Build-in MIDI to CV/gate converter with 16-bit resolution
Several parameters can be voltage controlled by external signals and, simultaneously, control external devices
by the build-in MIDI converters voltage outputs (see Rear Panel). The S1 is a stand alone instrument and the
possibility with patching and integrating it into an external modular (or semi-modular) synthesizer makes it
extremely flexible.
Introduction
4
Connections
Power; Connect the included power cable with a 115/230Vac outlet.
BEFORE YOU TURN ON THE MACHINE, BE SURE TO CHECK THE VOLTAGE SELECTOR POSITION
ON THE REAR.
AUDIO
Connect the INSTRUMENT OUTPUT of the S1 to your audio system. Use a single-ended or balanced
output cable, depending on what your audio system has to offer. For best audio performance, use the
balanced output. Please refer to your audio systems instruction for reference.
MIDI
If you want to play the S1 via MIDI, connect S1's MIDI IN to the MIDI OUT of your MIDI controller.
Select the corresponding MIDI channels on both the S1 and your MIDI controller.
All MIDI functions of the S1 are explained in detail later in this manual. Please also refer to the instructions
of your MIDI system/controller.
CV/GATE
If you want to play via CV/GATE equipped devices, please use the ANALOGUE INPUTS on the S1 rear panel.
Connect S1's CV IN to the CV OUT (1 Volt/octave) of your analogue sequencer or keyboard and connect
the GATE and/or Trigger or S-Trigger to the appropriate output of your analog controlling device.
