Filters

Notes: The Vermona Filter Lancet is a compact but versatile stand-alone multimode filter for your desktop. It's the right weapon against static sound and boredom and made for any kind of audio signal. The filter section itself has 3 modes: low-pass, high-pass and band-pass. The last one works with a slope of 12 dB per octave whereas low- and high-pass are 24 dB filters.

You can give the filter some extra punch with the Balls knob, known from Kick Lancet. It pushes low and high frequencies of the signal before being filtered. And of course the resonance is self-oscillating.

Other than the filter section of Mono Lancet, the Filter Lancet is not based on (Moog-) cascade circuitry. It was inspired by the filters of the Vermona M.A.R.S. respectively DAF-1 and Action Filter.

Without modulation the Filter Lanced would still be a good filter but kind of boring. So it is equipped with a LFO, an envelope generator, an envelope follower and a CV/pedal input. The LFO has 2 frequency ranges and goes up to 250Hz - that's fast. At low frequencies the LFO can be re-triggered by gate- or audio signals. It has sample & hold and five waveforms: saw up and saw down, square, sine and triangle.

The envelope generator can be triggered by the input signal or an additional audio signal as well as by a gate voltage. If triggering it via gate it works as an attack-sustain-release envelope. With audio triggers its mode is attack-decay. The envelope follower transforms the contour of the input signal into control voltages that can serve as modulation source.

The LFO modulation intensity can be set separately from modulation intensity of envelope generator and envelope follower on the VCF- as well as on the VCA section.

The Filter Lancet features a drive circuit right in the input section to add subtle shades of overdrive up to solid distortions.

The Filter Lancet is packed with useful features. It's a great and powerful addition to any synthesizer including Mono Lancet with or without Modular Dock. But Filter Lancet also is designed for stringed instruments. It creates standard effects like WahWah and tremolo with ease and even adds a palette of extraordinary sounds to any effect repertoire.

Notes: We have to admit being more than a little proud when thinking of the Action Filter's history. Twelve years ago we made the first version of this still popular stereo-filter with no end in sight. It still is built upon the same basic principle: ACTION!

Neither MIDI nor control voltage decide about filter sweeps and cues but you. Action Filter demands and supports your intuition and creativity. Reign over frequencies and rhythm instead of being a victim of technique.

What remains?

Like its predecessors, Action Filter 4 consists of a high-/lowpass filter-combination per stereo channel. Together, these either work as bandpass- or notch-filter with variable bandwidth and individual resonance per filter.

What's new?

Unspectacular but a spectacle nevertheless: Beside the mandatory RCA in- and outputs, Action Filter 4 is equipped with 1/4"-jacks. In addition, the FILTER MODE switch made it to the unit's front, labeled as STYLE.

Who is the Action Filter 4 dedicated to?

... of course for all action heroes! With jack- and RCA-connectors, Action Filter 4 is best suited for the DJ booth as well as for studio applications. You can use it to process full tracks or add that "certain something" to individual audio tracks. Emphasize or kill specific frequency bands and - on top of it - have lots of fun actively playing with frequencies! Simply: ACTION!

The Sherman Filterbank 2 Rack Analogue Filter and Distortion Unit is rack mountable unit with an ADSR generator, an FM input, a VCA overdrive and a ring modulator. The Sherman Filterbank is a powerful analogue filter and distortion unit that is equipped with a large frequency range and strong tube overdrive characteristics.

Easy to use, this unit is suitable for use in studio processing, compatible with editing sound sources, effect mixing and expanding modular systems. With the Filterbank 2 comes five extra switches and two extra LEDs, as well one pedal input jack on the back panel. The pedal input allows foot control of freq1 and bypass/effect switching. A 3-way switch on the input stage allows Hi boost and Hi cut.

WHAT'S NEW ABOUT THE SHERMAN FILTERBANK 2:

There are 5 extra switches and 2 extra LEDs, and on the back panel there's one pedal input jack. A reworked front-panel lay-out and the grey metal colour.

- The pedal input allows foot control of freq1and bypass/effect switching. You can rewire an old wah (because they have a switch on board) as shown by te diagram in 'extra stuff'.
- 5mm big green LED indicates "Effect on" on the FB 2
- 3-way switch on the input stage allows Hi boost as well Hi cut (both boosting high frequencies at input)
- Another 3-way switch allows "Sensitrig" (which makes the triggering twice as sensitive for, e.g. clean string pad filtering) and "Limit", which leaves the filters more "breathing room" for self-oscillation if the input stage is extremely overdriven.
- 3-way switch has 2 general transpose functions: +1 Octave and + Quint which works nice with monophonic signals, and has a specific dirty character.
- 3-way switch for the really powerful and quite revolutionary "Tracking" function - a monophonic pitch follower that tunes filter 2 to the incoming pitch, and makes filter 1 slave of filter 2 via the harmonics switch. E.g. in position 2, filter 1 will be pitched one octave higher than filter 2, but still following the pitch. This extra switch activates the "tracking" in a normal or deep "track low" position, with stunning basses as result.

- The "revolutionary" aspect of this function is that never before any similar system enhances "on the spot" harmonics and creates new harmonics with fat analog circuits.
- An extra white LED indicates when the tracking system is "locked on".
- At last there is an 3-way function switch in the LFO section, allowing saw-tooth wave shape OR AR retrig : this forces an LFO restart from the AR trig with pumping grooves as unavoidable result. If you want to receive a new brochure, please ask your dealer first.
