KXStudio : Applications : Catarina

Catarina is a Patchbay test app, created while the PatchCanvas module was being developed.
It allows the user to experiment with the patchbay, without using ALSA, JACK or LADISH.
You can save & load patchbay configurations too.

The Interface

A screenshot follows:

The 'File' menu and 'Project' toolbar provides actions related to projects: the common new, open and save.
The 'Patchbay' menu and toolbar allows you to control what's inside the canvas. You can add/remove groups, add/remove ports and manage connections.
The 'Canvas' menu and toolbar gives you control over the canvas zoom. The menu has actions for printing and saving an image of the current canvas.

As with all the Cadence tools, you can hide the toolbar via 'Settings' menu, and also configure Catarina.
The configure dialog looks like this:

You can change the theme used for the canvas (more on that below) and wherever or not to use bezier lines (will use straight lines if off).
Fancy Eye-candy has 3 states:

  • Unchecked (None): no eye-candy;
  • Partially (Small): applies drop-shadow to the boxes, this is the default;
  • Checked (Full): box drop-shadow, fade-in/out animations and line glow;

(Note: Full eye-candy currently is EXPERIMENTAL, and will make Catarina crash at random times. The cause of the crashes are under investigation).

You can also enable OpenGL for the canvas (so the entire 2D space is rendered in the GPU, which makes big projects render much faster) and Anti-aliasing.
OpenGL is experimental within Qt4 itself, and will not work properly on all systems.
Anti-aliasing has 3 states:

  • Unchecked (None): disable all anti-aliasing;
  • Partially (Small): applies only to the lines, this is the default;
  • Checked (Full): apply anti-aliasing everywhere;

Settings will be applied as soon as you press 'OK', no need to restart Catarina.
