Synthrotek DIRT Filter Now Available

synthrotek-dirtSynthrotek has announced that it has released the DIRT filter – a module that allows for distortion, mangling, wave shaping and other caustic and filter like effects.

Here’s what they have to say about it:

DIRT is our new 4HP low-pass filter / effect for the Eurorack modular synth platform.

Inspired by one of our favorite ‘noisy’ filters, the DIRT is an unapologetic filter / effect that produces interesting and unique effects via the Bias knob, accessible from the front panel.

It’s not a traditional filter; it’s an effects module with filtering, ring mod effects, wave shaping and even outright brutal harmonic distortion.

DIRT likes to square things up a bit, so throw in a triangle, sawtooth, sine or other wave forms for different style effects. Even plugging a guitar (using an external amplification module) into the DIRT produces some great sounds and heavy distortion.

Koma FT201 Step Filter Review

Sonic State’s Edd Butterworth takes a look at the Koma FT201 Analog Filter / 10-Step Sequencer – a voltage controlled vactrol state variable filter, combined with a 10 step sequencer.

The FT201 is capable of providing ultra low and high frequency filter effects, which are controllable with an on-board infrared expression controller, which lets you create filter sweeps by moving your feet or hands over the pedal. Continue reading

Zynaptiq Unfilter Removes Filtering Effects

Zynaptiq has introduced Unfilter, an adaptive tonal contour linearization effect plug-in for Windows and Mac that lets you remove the effects of filters, including comb filtering, resonance, or excessive equalization – effectively linearizing the frequency response of a signal automatically.

Unfilter can also copy a detected filter response and apply it to another signal, or export it to disk as an impulse response file (WAV), and can perform mastering grade adaptive, free-form, and graphic equalization. Continue reading
