The System 100 on
the recordings consists of eight components, 2 x Synthesizer 101, 1 x Expander
102, 1 x Mixer 103, 2 x Sequencer 104, 2 x Monitor Speaker 109. Each component
is relatively self-sufficient with its own power supply and housing. It was
Roland's idea that someone would start out with the Synthesizer 101 and add
on to it piece by piece.
Synthesizer 101
This is a self-contained semi-modular synthesizer with a 37-note (F-F) keyboard.
It features an ADSR, LFO, Portamento, a VCO (with pulse width modulation and
a tuning knob marked in Hz from 10Hz to 10kHz), white or pink noise, an audio
mixer (with sliders for VCO, Noise, and External Input), a high-pass filter,
a low-pass VCF, and a VCA with input for LFO. There are also buttons for auto-glide
and manual-glide and an A-440Hz tuning oscillator. All of this in 21 sliders,
five knobs, 14 mini-jack sockets, seven switches, and three 1/4" jacks
(for headphone and high and low outputs).
Expander 102
This is essentially a keyboardless Synthesizer 101, with a few exceptions. It
was designed to sit upright, behind the 101. Instead of glide controls, the
102 has a sample-and-hold module with variable lag time, and instead of noise,
the 102 has a ring modulator. The 102 also features weak and strong sync inputs
and a mix cascade jack socket instead of the tuning oscillator.
Mixer 103
This was a simple 4 X 2 mixer/amplifier, featuring panning, mono F/X send and
return, VU meters, a built in reverb, as well as separate left and right speaker
and line outputs. It was designed to sit to the right of the 101.
Sequencer 104
The 104 is a 12 X 2 step sequencer, featuring variable gate time, series or
parallel configuration, switchable ranges, and buttons for Start, Continue,
Stop, and Step. It was designed to sit to the left of the 101.
Speaker 109
Actually a pair of 16cm 3.5W speakers in angled boxes, designed to sit at either
side of the 102.
Roland had apparently
intended to design more components for the System 100 but chose, instead, to
put their efforts into designing the modular System 100m.
