crossbeam is a high-fidelity FPGA-based digital vectorscope for Eurorack.


  • Lowest possible latency between audio inputs and display.
  • CV-controllable persistance and color.
  • HDMI output for projectors / external monitors.
  • Based on Lattice ECP5 FPGA, supported by open-source FPGA toolchains.
  • 128MBit SPI flash + 128MBit HyperRAM (for framebuffer and persistance)
  • 4 DC-coupled audio input channels, 192KHz / 32bit sampling supported with oversampling interpolation.

This module is still in development.

Aiming for release some time in 2024.
