Rackmount stereo multimode resonant filter with DJ live features released at the end of the nineties with other effects like Warp Vocoder - The Filter Factory is multimode filter with LFO, distortion and envelope follower functions.
Overview
Rackmount Main panel is pretty simple: no display, 9 buttons and 7 knobs.
Rear panel terminal connectors:
- Midi interface
- Midi channel selector
- RCA stereo main out
- Jack stereo main out
- RCA stereo signal input
- Jack stereo signal input
- switch for input between phono and line impedance / RIAA
- 2 CV controller for filters cutoff
- pedalswitch input for bypass.
Voice
filter factory is basically split into 4 macro sections:
1- Buzz Distortion
2- Stereo Filter
3- LFO
modulation
4- Mixing section.
1 Buzz
special distortion can be added to the sounds with 2 parameters:
-
BUZZ is the amount of distortion and
-
TRIM is the relative gain.
2 Stereo Filter
2 indipendent resonant filter each with 2 poles (-12dB) each - can be set in multimode:
- low pass at 2 poles
- low pass at 4 poles (mono)
- high pass at 2 poles
- notch at 2 poles
- band pass at 2 poles.
The frequency cutoff can be controlled also by external CV tension.
3 Lfo
a single modulator with variable depth, 7 beat divisions, syncable to tap tempo or external Midi clock;
It features 5 shapes: positive sawtooth, negative sawtooth, triangle, square and random.
Modulation can be set also to special Envelope follower mode.
4 Mixer
this section allows final signal settings:
- EFFECT MIX balances between dry and wet
- BYPASS the function speaks for it self (can be assigned to external switchpedal).
Midi / Memory
all functions are mapped to Control Change #
It is possible to save a sound configuration using Midi sysex dump since there is no memory for storage.

Review
OK: -a lot of tweaks- interface, big knobs-price - 2CV
NOT : - resonance -sometimes too aggressive / unpredictable
"budget machine, often out of controland unpredictable, but double CV control is a very nice touch! OK I am not a fan of electrix product, I prefer Moog and Sherman filter stuff, however the factory can be interesting at fair price (no more than 150€) . "
