Project questions
How does Tang Nano 20K process audio?
CELESTE receives the PCM1808 signal and runs effects in the FPGA; PCM5102 provides 48 kHz output. The web interface changes patch parameters and routing.
Does USB carry audio?
In this firmware, USB carries control and telemetry. Audio enters through Line-In; HDMI displays instrument state and parameter values.
Does the free plugin require an FPGA?
The native plugin processes audio on the computer. Tang Control integrates hardware control; the plugin page provides an MP3 demo, Windows/macOS downloads and installation instructions.
