    Hi there

    After installation, dssi-vst works fine, but "vsthost any.dll" (for instance) launches jack with basic parameters that are not those from -jackd, so I can't use it for playing. Where can I find configuration files for vsthost ?

    stanlea,

    The vsthost does not explicitly start the JACK server: it just uses the jack_client_open mechanism to connect to a server. If no JACK server is running, this will cause the JACK client library to start a new server according to the contents of your /etc/jackdrc or ~/.jackrdc configuration file. If a server is found to be running already, no new server will be started.

    This mechanism is exactly the same as is used by most modern JACK applications, there really is nothing unusual about vsthost. You can override it by setting the JACK_NO_START_SERVER environment variable to 1, though that probably won't do anything useful in this case (it would simply make vsthost unable to start if no server was already running, since vsthost cannot run without JACK).

    The answer really is to make sure JACK is already running before you start vsthost, perhaps by using qjackctl or similar.

    Thanks for your answer, bq

    but I found the cause : I had just made a "make install" as su in the terminal and jack was called with the .jackrdc found in the root directory, which is not set with good parameters. A beginner's error, no more.
