Oakley Modular

The Journeyman is a 6HP, four-pole, dual-mode filter module featuring a unique, non-linear discrete circuit inspired by 1970s Japanese Traveller filters [1]. It offers switchable -12dB/octave...

The 6HP wide Oakley Classic VCA is a new version of one of my first Eurorack modules. This is a voltage controlled amplifier module inspired in part by a classic vintage design, the ARP4019...

This is a high quality single channel voltage controlled amplifier designed around an all discrete transistor core. It is based on the 4019 sub-module which is found in the classic 2600 semi-modular...

This is a 10HP wide four pole multimode filter module capable of -24dB/octave low pass, -12dB/octave low pass and +/-6dB/octave bandpass outputs simultaneously. The filter core is based on four...

The 10HP wide Oakley Croglin Voltage Controlled Filter (VCF) is based around two low noise ‘Sallen-Key’ filter circuits that operate either together or against each other. The cut off...

The Oakley Discrete Ladder Filter (DLF) is my reworking of the classic 1960’s low pass filter module. Inspired by the circuits of the 904A filter and CP3 mixer, the DLF combines them into one...

The 14HP wide Oakley Dual VCO, or DVCO, is two traditional sawtooth core voltage controlled oscillators in one module sharing a single common 1V/octave input. Each oscillator features a sawtooth...

The 6HP wide Oakley Envelope is an easy to use four stage envelope generator with switchable looping mode. The ADSR is operated by a traditional gate signal, but can also be triggered by slow rising...

The 8HP wide Oakley Sound Human Voice Module (HVM) is an all analogue audio signal modification unit that replicates some of the sounds made from a classic electronic keyboard first seen and heard in...

The 6HP Oakley Sound MOSPhaser is a six-stage, 1970s-inspired phaser featuring five variable all-pass filter stages that utilize a single 4009UBM CMOS IC for simplified, matched-component...

The 6HP wide Oakley Sound Eurorack Multimix is highly useful mixer module that can be used to process both control voltages (CVs) and audio. It is based on the original ‘Stooge’ version...

The Oakley SVF is a 10HP wide two stage multimode filter module capable of high pass, low pass, band pass and notch output modes. All four outputs are available simultaneously. The module is a stand...
