Analogue Solutions Tereshkova synth is modeled afdter the Vostok but it lacks the pin matrix patch panel and the VU meter. With the Tereshkova, instead of the Matrix panel and VU meter you get an extra LFO, 2 VCAs, 2 Multiples.
Like the Vostok, the Tereshkova 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.
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
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
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
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
