The Holland Synthesizer Model SM2000 is a 3U
Euro format* monophonic modular synthesizer. This is truly an
aerospace quality musical instrument, designed for the most
discriminating musicians, studios, and producers. The system
uses a backplane that carries control voltages, triggers and
audio signals to and from the various modules, however all patching
can be overridden from the front panel. All jacks are Switchcraft
1/4" for ruggedness. The SM2000 is designed to be a standalone
system, but being modular in nature allows for a high degree
The standard system contains the follow modules:
Triple Voltage Controlled Oscillator/ Mixer Module. Each oscillator
has six waveform outputs that can be mixed together. A fourth
mixer combines the outputs of the three oscillators and an external
signal source. Adjustable PWM and linear modulation. Coarse
and fine tuning on each oscillator and a master tune for all
3 tracking together.
Noise generator featuring white, pink, red and infrared sources.
Multimode Voltage Controlled Filter. Has 8 outputs. Low Pass,
High Pass, Band Pass and Band Reject (Notch). Each configuration
has a 12dB and 24dB per octave mode. Four overlapping ranges
with adjustable damping and manual frequency control.
Dual Envelope Generator. Two independant envelope generators
tied to the same trigger. Time at each stage adjustable from
1 millisecond to 18 seconds. Level attenuators for each output.
5 overlapping time ranges, and manual trigger. LEDs track stages
through envelope. Generates true linear envelopes.
Dual Log Voltage Controlled Amplifiers. Produces log output
with linear input. Unheard of 118 dB dynamic range. Input and
output level controls and CV attenuators. Manual offset controls
for ease of setup and maximizing dynamic range.
MIDI to CV and Trigger Interface.
Control Voltage Processor. Takes in a control voltage and produces
a copy and an inverted copy. Allows user to control offset,
gain and slew rate. Also has two outputs for adjustable, attenuated
versions of the outputs.
Multiples, Voltage sources and Attenuators. Has 3 four point
multiples, 4 adjustable DC voltage sources and 2 adjustable
Low Frequency Oscillator. Oscillator has two selectable ranges,
high for modulation, and low for filters and amplitude modulation.
Output waveforms are sine, triangle, square, pulse, positive
ramp and negative ramp. Also has controls for tuning and fine
tuning, pulse width, PWM attenuator, and two output level controls.
Fixed Filter Bank. This module has 12 resonant filters spaced
musically at about half octaves. Each filter has 10dB of boost
and cut. The highest and lowest filters are shelving type.
Buss Access, Power Monitor and Headphone Amplifier. Includes
4 volume controls for the audio output busses, and output jacks.
Also includes jacks for the 4 trigger outputs and 4 control
voltage outputs. Headpone output with level control. Power keyswitch
and LED power indicators for each voltage.
*Our modules are actually much more compliant
to Euro format than most other manufacturers. The Euro format
(which is technically called DIN 41612) specifies that modules
will be a minimum of 160 mm deep and use a 96 pin connector
to get power and signals to and from a backplane. This is far
too expensive for most manufacturers. We adhere to the majority
of this mechanical specification, except for our backplane which
is optimized for audio signals. Therefore, our modules are too
deep to fit in our competitors racks. We also use higher supply
voltages and different power connectors than most other companies.
However, our audio inputs and outputs, control voltages and
triggers are compatible with most other Euro format synthesizers.
