Electrix Filter Queen

A half-rack analogue filter from the Electrix line, with an envelope follower, an LFO and an expression-pedal input. On my table now.

The Filter Queen is a half-rack analogue filter from Electrix, the performance line IVL Technologies made in Victoria, British Columbia, around 1999 to 2002: a resonant filter with an envelope follower, an LFO and an input for an expression pedal, made to be played rather than programmed.

I use three of the Electrix boxes now: the Filter Queen, and the Filter Factory and Mo-FX. I never used the Repeater, the looper in the line; two people I played with did, Brandt Passalacqua and Gregory Cage.

The lineThe Electrix performance line, from IVL Technologies in Victoria, British Columbia, around 1999 to 2002: the Repeater, a four-track loop sampler; the Filter Queen, a half-rack analogue filter; the Filter Factory, a full-size stereo analogue filter; the Warp Factory, a vocoder; the Mo-FX, a tempo-synced multi-effect; the EQ Killer, a three-band isolator. The line was discontinued in 2002.

All three nowadays, and I have a lot to say about them.

On my table

The three filters sit with Kyma and the Continuum. What each one does in the chain is mine to write.

My thoughts

The line is as the Electrix units are documented; which of them are on my table is as I said on September 26, 2026.
