And for those wondering, no, there is no relation to this site. Matrixsynth in this case stand for the matrix modulation patch bay. The site got it's name from my alias, matrix, and the Oberheim Matrix-6, my first synth. I registered the matrixsynth.com domain name back in 1997, long before the Vostok Matrixsynth.

"The Vostok combines the patch panel convenience and all-in-one instrument approach of the EMS Synthi with the with the open-system nature of eurorack modular. The module selection in the Vostok is second to none as far as versatility and economy.

The Vostok has far more features packing a powerful amount of modular synthesizer power into one small suitcase.

This Vostok is in perfect working condition and only used in the studio.

Matrix Patch Panel

Utilises the EMS VCS3/AKS style patch panel, but with an with increased 22x22 connection size. The matrix panel gives the patching versatility of a modular without the need for confusing & front-panel interfering patch cables. It's the neatest & most versatile method of creating patches.

External Patching

Matrix panels alone do not allow interfacing with external synthesizers & signals, so the Vostok also provides a full complement of front panel jack socket patch points for additional internal & external patching & interfacing.

All circuits are totally analogue with the exception of the MIDI interface.

Utility Modules

Mixer: CV / Audio Mixer. 6 input with Normal and Inverse output
Signal Meter: The meter input is taken from the mixer output
Multiples 1 and 2: 2 multiples, each is 4 way
Adaptor 1: 6.35mm / 3.5mm jack socket converters
Adaptor 2: 6.35mm / 3.5mm jack socket converter wired into the matrix board

Control Modules

MIDI to CV Converter: CV1 (pitch) / CV2 (controller) / Gate / Accent / Legato, MIDI Thru, channel select, manual trigger
Joystick: 2 way joystick controller
Sequencer: 8 step CV & Gate analogue sequencer, range switch, manual step

Audio Modules

VCO1: Saw / Square waves, Pulse Width, Glide, Sync
VCO2: Saw / Square waves, Pulse Width, Glide, Sync
VCO3: Saw / Square waves, Pulse Width, Glide, Sync
Noise: White noise source

Voltage Controlled Multimode Filter:

2 Filters based on Korg MS20 circuitry. Independent Cut Off and Resonance for Low Pass Filters and High Pass Filters. The VCLPF and VCHPF combine to produce a 3rd filter type, Band Pass

Voltage Controlled Amplifier:

VCA wired in series with the VCF output. With 1/4" jack audio output.

Ring Modulator: AC ring mod

CV Modules

EG 1: ADSR envelope generator, Norla/Inverse output, Repeat function
EG 2: ADSR envelope generator, Normal/Inverse output, Repeat function
VCLFO1: Ramp, Reverse Ramp, Square,Triangle waves, Voltage controlled frequency
VCLFO2: Ramp, Reverse Ramp, Square,Triangle waves, Voltage controlled frequency

Sample & Hold:
S&H with Slew

Matrix Patch Panel

Utilising ムEMS VCS3メstyle patch panel with 22x22 connections. The patching versatility of a modular without the need for confusing & front-panel interfering patch cables.

Lead Patching

Jack socket patch points provided for additional internal & external patching & interfacing.
LEDs:13 of them! 4x7 segment wavetable display

Dimensions

Dimensions shown do not include feet/handles/catches/corners pieces. Complete closed case: 10-13/16"H x 17-3/8"W x 7-7/16"D Lid depth: 2" inside (enough to leave in patch leads)"
