The Sound of Shadows (SoS) is a voltage-controlled (VC) digital delay
module based around the PT2399 echo IC
was, by the way, originally designed for Karaoke equipment. 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, not just hoover
And remember: every instrument has its quirks and unexpected aspects,
so RTFM
