The final jack connection setup which we are aiming for is shown in the images below. Since I am writing this away from my studio, I will use vkeybd to stand in for my real midi controller keyboard. I will use ardour, hydrogen and whysynth as the tools to be connected. ![]() Since I am far too shy to stand up and perform live in front of an audience, I will attempt to describe how to use the patchbay to implement a simple studio rig which I can use to record drums, keyboard track and a single vocal. When it is setup correctly, the patchbay provides automatic connection setup for jack-aware applications, maintains connections persistently through application stops (or crashes) and restarts, and allows for easy switching between different setups (eg from one instrument setup to another between songs in a live performance). It is not an explanation of how to setup jack, qjackctl or any other tools and assumes that you can already do that but I hope it will be useful to somebody nevertheless. This document is my attempt to share that understanding with those in the same position as I was. Now, thanks to various hints on the linuxaudio mailing list, I think I understand how it should work and how useful it could really be. They both seemed to show the same information and the patchbay was not very useful. When I started using qjackctl I couldn't understand the difference between the patchbay and the connections window. You've done, in just a few paragraphs, what I've failed to do in all those four years QjackCtl's Patchbay has been around ) Cheers. ![]() ![]() Thanks Simon, for this excellent piece of work. Because of that, he has written a brief guide to using the patchbay and the document is here first released into the wild, hoping it will turn out to be useful to someone in the quest to make amusing noises at home. Fielding writes that after quite some time, and reading between the lines of various posts on the linuxaudio-user mail list, he has finally understood how the QjackCtl Patchbay works and what it is for.
