Threeler VCF from Ian Fritz and

The Threeler VCF created by Ian Fritz is an interesting filter design. Utilizing a 3rd order design with 3 single pole filters in various combinations the Threeler is able to give a large variety of filter types. A mode select switch gives us 4 options of slopes. the first row consisting of Low pass configurations, the second row consisting of band pass , the third is a reversed order bandpass  and the bottom row consisting of high pass filters. we are give 3 simultaneous outputs at a time (giving us access to different stages of the filter.) CV is available to control filter cut off, frequency modulation and resonance. The Filter also tracks volt per octave nicely over quite a few octaves which gives us access to a nice sine oscillator.

Available now as a PCB, Panel PCB, full Kit and as a completed module from or on their Synth release club ( a module renting/leasing program.

Writeable QuantizerbartonUwq03-800x800

The writeable Quantizer(WQ) is an interesting module in that while it can function like a traditional sequencer, it is anything but traditional. What sets the WQ apart is that this quantizer doesn’t come with preset 1/12v divided scales like most quantizers do. Instead the WQ allows users to store voltages into a user defined “scale” and then quantize incoming voltages to those stored voltages. You can use traditional scale values and write those voltages to a traditional scale but what is the fun in that? Continue reading
