Description
The Vostok may at first glance look like an EMS clone, but it is not. It may share the matrix panel and suitcase style design, but thatメs where the similarities end. The Vostok has far far more features packing a powerful amount of modular synthesiser power into one small suitcase.

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メ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
