Is there any Zynthian API?

There is an incipient OSC API based in the CUIA but it’s not explicitly documented. Basically you can call any CUIA using OSC in the port 1370 (UDP).

You can get a list of the currently implemented CUIA actions in the source code:

It’s pending to document in the Wiki the CUIA API using MIDI and OSC, but it’s quite new and still changing too fast, so better to wait a little bit :wink:

Kind Regards,
