jConvolver with Jc-gui

• 1. With the Jack audio server running, start Jc-Gui (Multimedia -> Multimedia -> Jc-Gui)

  2. Click on 'jconvolver settings' (this will open the jConv Settings window, you may need to drag the window to the center of your screen)

  3. Click on the 'Open file' icon (the folder image)

  4. Navigate to your reverb wav files and select one by clicking on it

  5. Click on Open (the folder icon) [if your text is white on the light blue background, just look closely at the screen to see the text]

  6. Wait for the wav file to be loaded. You should now see it in the preview window.

  7. Don't worry about the other buttons and dials, those are for tweaking the reverb

  8. Click on Ok to close the Jconv Settings window

  9. Now click on the 'run jconvolver' button

  10. After a few seconds (or a little longer with the older computers) the 'run jconvolver' button should turn bright green, indicating that jconvolver is loaded and running

  11. Take note of the wet/dry slider above the four dials above the buttons that we have used

Now we need to connect the output of the fluidsynth soundfonts to the reverb, and connect the reverb to the speaker outputs. We will do this in the Jack Control Audio Connections tab:

• 1. Right Click on the Jack Control icon on the bottom right hand side of the Menu bar

  2. Select 'Connections' from the menu

  3. Click on the 'Audio' tab at the top of the Connections window if it is not displayed by default

  4. Select a jOrgan fluidsynth jack output from the left hand side, then select the jconvjc port on the right hand side and click on the Connect button

  5. Do the same for all the other fluidsynth ports that you want connected to the reverb

  6. Now select the 'jconvjc' port on the left hand side and select the 'system' port on the right hand side, and click on the Connect button to connect them [This connects the fluidsynth outputs to the jconvolver input stream, and the jconvolver output to your speakers]

Now play the organ, and use the wet/dry slider mentioned above to get the right about of reverb mixed in to the audio stream.
