Description

The Recursive Machine is a portable, battery-powered, semi-modular synthesizer / noise machine from THC, the designer of the popular TTSH and 73-75 DIY projects. Recursive Machine features 2 VCOs, 1 VCF, 2 VCAs, 2 LFOs, a mixer and an effects section with distortion, digital spring reverb and 2 x PT2399 delays. The synth has a pre-wired signal path but this can be changed or expanded by patching. For example, VCA 1 and Delay 1 are controlled by LFO by default, while LFO2 affects VCA 2 and delay 2. The oscillators feature frequency modulation (FM) and other components such as the filter, distortion, and reverb have CV inputs for modulation. Another highlight is that the synthesizer is battery operated and includes a built-in speaker, so it can be used anywhere as a portable noise machine!

This is the latest PCB revision with the switch footprint changed from a rocker to a 3-way bat (SP3T ON-ON-ON) – so the filter is now HP/BP/LP. The reverb has the feedback mod permanent, so the blend knob now controls feedback.
