Problems with the bouncing echo

mic, 2011 04 20: The "bouncing echo" is simply an echo with a sweeping delay. I called it a bouncing echo, as in its simplest case it is similar to a bouncing ball. If you let a ball bounce the time between each two bounces will get smaller and smaller. You can set up the bouncing echo so that the delay between each two repetitions gets progressively smaller, which is pretty much like the bouncing ball. However, the bouncing echo is much more complicated than that. You could have, for example, you can have slowly decreasing delay that suddenly reverts and starts slowly increasing. This sounds almost like driving while accelerating by a ball that bounces at a constant speed.

The screen for the bouncing echo has two graphs. The bottom graph is not that important. It simply shows the impulse response of the effect - how the sound repetitions are spaced and how they decay. The top graph, which I call the "sweep graph", shows the delay sweep of the echo. Each point on the graph is a repetition at which the delay begins to accelerate, decelerate, etc. The whole point of this graph is that it should allow the user to add points or to select and move points to create the sound effect.

The problem was that the sweep graph didn't actually allow the user to add or move points. This was fixed and uploaded on April 20, 2011 with version 2.2.1 of Orinj.
