The **TBD-16** is a compact desktop audio DSP instrument powered by an
`ESP32-P4 <https://www.espressif.com/en/products/socs/esp32-p4>`_ (400 MHz dual RISC-V)
and an `RP2350B <https://www.raspberrypi.com/products/rp2350/>`_ (150 MHz dual Cortex-M33).
Plug in power and start making music --- no computer or Eurorack case required.

Proven Lineage
--------------

The TBD audio engine has been shipping in hardware for years across multiple form factors:

- **TBD-16** --- Current-generation desktop instrument by dadamachines
- **CTAG TBD Eurorack** --- The original open-source module
  (`upstream repo <https://github.com/ctag-fh-kiel/ctag-tbd>`_),
  commercially sold by
  `Instruments of Things <https://instrumentsofthings.com/products/tbd>`_
- **AE Modular TBD** --- Compact adaptation by
  `tangible waves <https://www.tangiblewaves.com/store/p149/TBD.html>`_
  (`wiki <https://wiki.aemodular.com/#/modules/tbd>`_)
- **Open-source core** --- Upstream repository:
  `ctag-fh-kiel/ctag-tbd <https://github.com/ctag-fh-kiel/ctag-tbd>`_

See :doc:`Custom Integration <30_custom_integration>` for details on building your own product on this platform.
