The Kreuzung was conceived as a companion device to the
FloriVoxTron, with its case dimensions precisely matching the top of the
FloriVoxTron for seamless integration. Its primary purpose is sample playback,
but it also offers an extensive array of sound modification modules, including
a looper, modulated filtering, bit crusher, and more.
From a hardware perspective, the Kreuzung is generously equipped. Sample playback is handled by the Robertsonics Tsunami sample player, while effects processing is managed by three Daisy Seed Patch SM modules. The main control unit is a Teensy 4.1 microcontroller, and the LCD interface is powered by a Raspberry Pi Pico.
A unique challenge in this project was designing the front
panel. Departing from my usual scientific layouts, I opted for a design
inspired by orbital patterns. Although the layout remains mathematically influenced,
it features fewer straight lines, creating a more organic aesthetic. The opaque
discs on the panel illuminate in different colours to indicate their status,
and each wooden knob in a column controls the corresponding parameter.
The Kreuzung includes eight performance control panels. Each
panel is equipped with two sensors and one control: a backlit pressure sensor
that can be assigned to nearly any parameter, a chromed touch switch, and a
small knob that serves as a lag control for the pressure sensor. This
configuration provides four control points per panel, generating four
assignable signals for flexible parameter control within the Kreuzung.
Currently, I am refining the firmware for the main MCU, focusing on communication with the LCD MCU to display parameter values accurately. My goal is to have the final machine fully operational by mid-2026.
