AJH SynthMatrix VCF Vintage 16 Mode Filter + VCA

AJH Synth Matrix VCF

The Matrix VCF from AJH Synth is an analog multimode filter with a daringly vast range of sixteen total filter types, taking inspiration from the acclaimed Oberheim Matrix 12 to help you sculpt sounds without limits. Adding a full four-pole, all pass phaser mode to the original fifteen filter types from the Matrix 12, Matrix VCF brings uncompromising versatility to any Eurorack system. All your favorites are here – high pass, low pass, band pass, all pass, and notch – each featuring multiple implementations with varying poles, as well as combinations of multiple types in a single mode. Lined up in a glowing LED-menu of spectral shaping delights, modes can be selected by hand or directly controlled via the provided CV input.

Sure, with sixteen filter types this would easily be one of the most versatile filters in Eurorack, but why stop there? The onboard P-Vox resonance distortion circuit, inspired by the uniquely saturated filter core in the famed Soviet synth. This circuit alters how resonance behaves in each mode, introducing a richer character and ensuring self-oscillation in all filter modes, essentially expanding the total filter types to a whopping thirty-two modes. In addition to a dedicated 1V/Oct CV input, Matrix VCF gives you comprehensive control over filter frequency, with an attenuated frequency CV input and both 1/3 and 2/3 scaled CV inputs, perfect for keyboard filter tracking and more.

Adding the final sprig of zest to this feast of filters, AJH Synth has included an onboard VCA, providing a deeply powerful yet compact voice when paired with an oscillator and envelope. Whether you're a dedicated Matrix 12 fan or simply appreciate filter freedom when patching, the Matrix VCF from AJH Synth is a fantastic addition to any system.
