Most Eurorack modules ask what you’ll do with their fixed feature set. This one asks what you want the hardware to become.
Tiliqua by apf.audio is an open-hardware, FPGA-based audio and video multitool designed as a fully reconfigurable playground for digital signal processing. Behind its 6 HP panel sits a Lattice ECP5 FPGA (LFE5U-25F-6BG256) paired with 32 MB of PSRAM, giving you the horsepower to run ambitious custom instruments, processors, or video experiments entirely in the rack. It offers eight high-fidelity, DC-coupled audio channels at 192 kHz (four in, four out), so you can patch anything from precision CV generation and analysis to multichannel spatial audio and complex feedback networks.
High-speed USB (host or device) lets Tiliqua talk fluently to computers, controllers, and other USB gear, while two PMOD-compatible expansion ports open the door to custom I/O and future hardware add-ons. A built-in debugger, support for multiple stored bitstreams, and a bootloader for on-the-fly selection mean you can swap personalities mid-set, turning the same module into a synth voice, a multi-effect, or a video generator in seconds. Developed around a Python-based DSP and Amaranth HDL workflow, it’s engineered to make FPGA-based audio and video design drastically more approachable, whether you’re prototyping your first digital module or building an entire open ecosystem around a single, remarkably flexible piece of hardware.
