Estradin 230 is powerful monophonic 3'osc synthesizer produced by Estradin military radio plant in 1985 in Zhitomir city. Synth has 4-oct keyboard (F-C) with velocity sensitivity assign to vibrato effect. For live performance there is a wheel which provides pitch shift (called glissando). Synthesizer is based on 3 VCO (OSC-3 can work as the modulator), 1 VCF (lowpass 24dB/oct) with ADSR, 1 VCA, LFO, noise generator (white/pink), portamento(glide), memory. It has an EXTERNAL INPUT allowing to use FILTER and GENERATORS with OTHER INSTRUMENTS such as guitars, synths, etc! Estradin 230 consist of 5 main sections - OSC'S, MODULATION, MIXER, FILTER and AMP (called Contour).

OSCILLATORS section:
- osc 1,2,3 registers - 2", 4", 8", 16", 32", Low Frequency
- osc 1,2,3 waveshape select - triangle, sawtooth, reverse sawtooth/ramp wave, square, two different width pulse waves
- osc frequency - freq 1..3, freq 2, freq 3 -linked to keyboard pitch on/off
- modulation on/off switch

MODULATION section:
- portamento on/off, rate;
- mod mixer knob: balance between modulated by OSC3 and noise, depth amount;
- vibrato on/off, octave shift to 1/2
- pitch wheel (glissando)

MIXER section:
- osc 1,2,3 on/off, level
- ext input level, on/off
- noise generator level, on/off
- noise mode switch: white/pink

FILTER section:
- mod on/off
- cutoff, resonance, brightness
- attack, decay, sustain, release
- keytrack on/off

AMPLIFIER section:
