Hey Rui, at the moment, i am writing a small DSSI plugin ... and as soon as i started, i ran into some problems, where i need your help: 1. I can start my plugin with "jack-dssi-host" without problems. It has 1 MIDI and 1 Audio input. When i load the dssi plugin into qtractor on a MIDI track, everything seems to work fine. But when i try to load it on an audio track, qtractor exits with a segmentation fault. Do you have any idea, that could help me? Du I need to write the plugin in a stereo-version? 2. The plugin also needs a GUI i've written in QT. This works fine, and qtractor does start the GUI. But the DSSI ports which are set by qtractor are not send to the GUI? Is there a special mechanism to load all the data for the GUI on startup? I think, the host (qtractor) calls something like an update-method? 3. My plugin has some control ports, and they all seem to work fine. But i do need a control port output at the plugin, so that a response can be sent to the plugin gui (which is also started fine by qtractor). So i created a control port as output of the plugin. Now, when i change the data of this port from within the plugin, the GUI and qtractor do not recognize that the value has changed. Do you know if there's such a mechanism? If my questions are to annoying for you, please do just forget them. But maybe you got the hint for me, that i am missing all the time ... Regards, gizzmo |
