  • Pulse on Steroids: Russian Filter Upgrade for Waldorf Pulse

    The Russian Multimode Filter integrated in the Pulse - a Synthesizer on Steroid!

    The filter of the original Polivoks synthesizer built by Vladimir Kuzmin is legendary for its powerful and mangy sound. Nothing in the world is that fat! The new Virtual Music Russian Filter Upgrade is a faithful replica. It is a small circuit board, designed for installation in the Waldorf Pulse.

    The distinctive aesthetics of the Russian Filter under the control of a powerful modulation matrix make sonic dreams come true. With relatively little effort, this Filter Upgrade transforms the Pulse into a fantastic sounding analog monster that even outshines some famous vintage synthesizers.

    A very powerful Sound

    The Russian Filter Upgrade sounds like the legendary original. The sound is creamy and powerfully mangy. Higher oscillator levels produce juicy saturation effects. With stronger resonances, the filter begins to scream passionately.


    New Filter Modes 400 Russian Filter Upgrade - Signal Flow

    According to the Russian original filter, this Filter Upgrade offers low pass and band pass filter modes. The original Pulse filter still remains and can be used at any time.

    Filter Modulation by Oscillator 3

    Oscillator 3 can be used as modulator for the filter cutoff frequency. In that case OSC 3 level defines the strength of the modulation. Filter modulations in the audio range create spectacular effects in a simple way - previously impossible for the Pulse.

    Easy Operation

    The desired filter setting and the filter modulation by Oscillator 3 can be selected directly from the panel - a simple and quick process.

    Design and Manufacturing

    The signal path of the Russian Filter Upgrade is intransigently kept in the style of the 80s. The handmade production and the use of authentic components (NOS!) are our commitment to local workplaces and high quality. Therefore we are happy that we can offer this fantastic filter for the price of a Eurorack module!

    Installing the Russian Filter Upgrade

    500 Russian Filter Upgrade - Board installed

    The Russian Filter Upgrade is a fully assembled and tested circuit board which will be installed in the Pulse. The instrument remains unchanged in its appearance. For the installation, the Pulse is dismantled and soldering and screwing work is required (16 wires soldered on, two capacitors unsoldered and a conductor path cut). The detailed instructions make the installation clear.

    The installation requires basic knowledge in electronics. For those with a talent for technology, the installation should be done in 90 minutes. Otherwise, professional support is recommended. Alternatively, Virtual Music can take over the installation for you.
