Hey all, I'm currently trying to fix the reverb in Luppp and I'm running into a rather strange bug: I have an array of floats that is used to set the plugins parameters: its called controlBuffer. The following code connects the ports to the addresses of the float buffer. The crazy thing is: The print outs before & after the connect ports are different! I don't understand how this is possible, but perhaps I'm missing something LADSPA. cout << "Decay: " << controlBuffer[4] << " Wet: " << controlBuffer[8] << " Dry: " << controlBuffer[9] << " preDelay: " << controlBuffer[10] << " highDamp " << controlBuffer[5] << endl; descriptor -> connect_port ( pluginHandle , 0 , buffer ); descriptor -> connect_port ( pluginHandle , 1 , buffer ); descriptor -> connect_port ( pluginHandle , 2 , &outputBuffer[0] ); descriptor -> connect_port ( pluginHandle , 3 , &outputBufferR[0] ); descriptor -> connect_port ( pluginHandle , 4, &controlBuffer[4] ); descriptor -> connect_port ( pluginHandle , 5, &controlBuffer[5] ); descriptor -> connect_port ( pluginHandle , 6, &controlBuffer[6] ); descriptor -> connect_port ( pluginHandle , 7, &controlBuffer[7] ); descriptor -> connect_port ( pluginHandle , 8, &controlBuffer[8] ); descriptor -> connect_port ( pluginHandle , 9, &controlBuffer[9] ); descriptor -> connect_port ( pluginHandle ,10, &controlBuffer[10] ); descriptor -> connect_port ( pluginHandle ,11, &controlBuffer[11] ); descriptor -> connect_port ( pluginHandle ,12, &controlBuffer[12] ); cout << "Decay: " << controlBuffer[4] << " Wet: " << controlBuffer[8] << " Dry: " << controlBuffer[9] << " preDelay: " << controlBuffer[10] << " highDamp " << controlBuffer[5] << endl; Example Output: Decay: 4.7685 Wet: 0.70709 Dry: 0.696707 preDelay: 50 highDamp 0 Decay: 1.5 Wet: 0.25 Dry: 1 preDelay: 0 highDamp 5000 The problem is that the reverb plugin doesn't react to my input parameters, but just processes based on the 1.5, 0.25 wet, preDelay 0, and highDamp 5000 *all* the time, and there's nothing I can do about it. Am I doing something fundamentally wrong? I've tried connecting the ports every process(), once, and then leave them. I've hard coded values, it seems to make no difference.
