Analogue Solutions SY02 Multimode Filter w/ VCA – Korg MS20 Clone Filter Module

February 23, 2012 · Posted in Uncategorized · Comment 

The beating heart of the VOSTOK MATRIXSYNTH!

The SY02 is as close a clone of the MS20 filter as is possible without digital modeling. It uses the same circuit design. It uses all the same components, except for 2. 1 of which will not affect the sound, the other has been superseded by a part that is essentially the same. In all other respects they are the same.

Not all MS20s sounds the same, and for the same reasons not all Filtered Coffees or SY02s will sound identical to each other or the MS20. Reasons could be trimmer setting variations, component tolerances, but these are the consequences of buying analogue! We believe that the FC and SY02 do sound like MS20 filters, if you don’t it must be imagined!

Controls

Input Level
This sets the input level of the audio signal into the filters.

HPF CV
This sets the level of external CV that affects the HPF cut-off. Set at minimum, the external CV has no effect, set at maximum, the external CV has full effect.

LPF CV
This sets the level of external CV that affects the HPF cut-off. Set at minimum, the external CV has no effect, set at maximum, the external CV has full effect.

Initial Level
This sets the initial level of the VCA. It applies a voltage to the VCA that opens it up. Set to maximum, the VCA will pass signals through at full volume. This would be the normal way of using this control. As the control is turned to minimum, the level of the VCA decrease finally to zero. In this case, an external CV is used to control the VCA level (such as an envelope signal).

HPF Cut-Off
This control sets the cut-off frequency of the HPF. As the controls is increased, more lower frequencies are filtered out (only high frequencies are allowed to pass through).

HPF Resonance
This alters the resonance of the HPF. Set to maximum it will self-oscillate producing a continuous sinewave. In this way the SY02 can be used as a VCO.

LPF Cut-Off
This control sets the cut-off frequency of the LPF. As the controls is increased, more higher frequencies are filtered out (only low frequencies are allowed to pass through).

LPF Resonance
This alters the resonance of the LPF. Set to maximum it will self-oscillate producing a continuous sinewave. In this way the SY02 can be used as a VCO.

Volume
This sets the final output volume of the SY02.

Sockets

VCF IN
Audio input to the filters.

HPF CV
External CV input to control the HPF cut-off frequency.

LPF CV
External CV input to control the LPF cut-off frequency.

VCF Audio Out
This is the audio output from the VCF

VCA IN
Audio input to the VCA

VCA CV
External CV input to control the VCA level.

VCA Audio Out
This is the audio output from the VCA

Analogue Solutions Telemetry (Mini Vostok) Analogue Synthesizer

February 21, 2012 · Posted in Uncategorized · Comment 

Here’s a look at the Analogue Solutions Telemetry (mini vostok) synthesizer.

http://analoguesolutions.org.uk/v2/telemetry-mini-vostok/

This video features various sound types from the Telemetry synthesizer, each within a musical context (beats added). All synthesizer sounds come from the Telemetry and all of the sounds were tweaked live in the video, and recorded direct.

Given the vast open-ended nature of Telemetry (pin matrix, patching), the sound possibilities are immense and virtually limitless. If you want to go nuts sonically, Telemetry is for you!

The video is roughly 10 minutes and barely scratches the surface.

Some sounds were sequenced or played live via MIDI, while others were triggered via the Uewerkuer “Ice Machine Sequencer” [ Oberkorn MK3 ].

As usual, all patches, music, and tunes are 100% original.

Enjoy.

Analogue Solutions VOSTOK MATRIXSYNTH v2 – Modular Suitcase Synth Demo

January 23, 2012 · Posted in Uncategorized · Comment 

Here’s an extended look at the Analogue Solutions Vostok MATRIXSYNTH synthesizer.

This demo features a variety of sound types and sequences (traditional and non-traditional) demonstrating the Vostok’s sound palette and variety of timbres. All sounds, with exception of the obvious acoustic drums (used for context), are created on the Vostok using either traditional patching or the pin matrix — or a combination of both.

Sounds are being driven by either the on-board sequencer, MIDI sync (via GATE to CLOCK), or direct MIDI connection to a controller keyboard.

Emphasis for this video was more traditional synth sounds (basses, leads, sequences) as there are plenty of non-traditional (fx, ambient, noise) sound demonstrations on YouTube. The filter section at the heart of the Vostok was also a focal point of this video and is tweaked extensively for the various sound types.

Also, see the Telemetry (mini Vostok) in action at the following link:

KEY FEATURES OF VOSTOK Pure analogue voice circuitry. Suitcase style design. 22×22 matrix pin panel. Rugged Steel construction. Quality chrome catches and cool steel spring handle. Stuffed full of electronics. No front panel space is wasted. Joystick, retro-VU meter, MIDI, jack socket patch points, more, more, more!
