Ok, got it working in Qtractor: - In Qtractor I've created four tracks with corresponding buses: Formant Synth (1 channel), Carrier Voice (1 channel), Vocoder (2 channels) and Vocoder Mix (2 channels) - All tracks output their signal to their corresponding buses, except for Vocoder Mix which outputs to the Master output buses - Then I've loaded the vocoder LADSPA plugin into the Vocoder track. Input 1 of the Vocoder bus is the carrier and input 2 is the formant - After that I've made the following connections in Qtractor's Connections window: http://linux.autostatic.com/images/2010-07/vocoder-connections.png Best, Jeremy _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/listinfo/linux-audio-dev
