DIY Kit of the Sound Of Shadows module. Build documentation here. The Sound of Shadows (SoS) is a voltage-controlled (VC) digital delay module based around the PT2399 echo IC. The SoS is essentially two separate modules: a delay and a voltage-controlled amplifier (VCA). The focus of the SoS was the delay while the VCA was thrown in because half of an LM13700 IC was unused, so the VCA is very basic. As with all f(h) products, the SoS was engineered towards maximizing functionality while keeping cost as low as possible. If some aspects of the unit seem awkward, it is most likely due to this. The goal is to make unique, useful, enjoyable, and affordable instruments. And as always, make sure you read the manual! Especially with the quirky ones.
