ALISA 1387 is a compact monophonic melodic synthesizer, produced by Lubertsy EMI factory. It has a 3-octave keyboard, a modulation wheel, control knobs and regulators. The process of synthesis is performed with the 2 OSCs, 1 sub oscillator, noise generator, filter with ADSR, 1LFO, and wide range of modulation functions. The synthesizer plays a stable keyboard pitch thanks to quartz stabilization of oscillators.
ALISA consists of 7 main
sections - OSCILLATORS (called TONE GENERATORS), MIXER, FILTER with ADSR (called
FILTER CONTOUR), AMPLIFIER ADSR (SIGNAL CONTOUR), and OUTPUT section.
OSCILLATORS section has three subgroups - OSC 1-2 (called GENERATOR 1 and 2), and REGISTER (waveshape). Their parameters are the following:
- osc1: waveshape switch (pulse, saw, and square - can run simultaneously!), pulse width modulation (wave forms 1 and 2) levels;
- osc2: waveshape (saw/square), sync interval, sync on/off;
- register: 8'', 16'', 32'' and subharmonic; next - portamento on/off, level and global tuning.
MIXER section - osc's 1-2 levels, noise generator level.
FILTER - cutoff, resonance, filter vibrato, key follow.
FILTER CONTOUR - attack, decay, sustain release (called amplitude) also switched on/off.
SIGNAL CONTOUR - attack, decay, sustain (only on/off), release.
OUTPUT - main volume level, power on/off.
MODULATION section(left from keyboard) - mod depth wheel, mod purpose - osc/filter, waveform switch - saw/square, rate (called tempo).
On the rear panel, the CONNECTION
plugs are located:
- line out plug;
- power source - 220V/50Hz, cord plug, fuse;
- external run - osc control plug, input and output plugs, on/off switch;
- phones out (located below Modulation section)
The synthesizer may be successfully
used with music of various styles, as a solo instrument for live performances
and as an experimental device for studio or home work as well. It provides
the sound of original colour, has a considerable potential and well-developed
modulation functions, along with a handy modulation wheel. The synthesizer
provides warm, rich analog timbres; it is ideal for creating smooth leads,
fat basses, aggressive techno synths, percussion and much more
samples). ALISA-1387 is the most reliable and high-quality Soviet synthesizer.
