Research document documenting feasibility, architecture, and hardware constraints for running two independent DSP chains (guitar + bass) simultaneously on RPi 4B with Focusrite 2i2.

Key findings:

  • Dual chains with Feather NAM models are feasible
  • Standard NAM models require LV2/NeuralAudio compiled backend
  • Existing Channel enum in types.py provides groundwork
  • Recommended: approach A (two AudioPipeline instances)

See: docs/dual-channel-architecture.md
