Kaiku. It is unfinished. I'm stuck. A lot of help needed! Don't use
seriously. Not all important controls are in GUI.

Kaiku is now GVerb plus multitap, but will improve to different
structure which I have already designed. I will complete the reverb
code if the problems will be fixed.

(1) Need better GUI. Control envelopes on time-axis for
a few features. GTK2 and/or OpenGL. We discussed about the
great amount of callbacks used in my GTK code years ago but
I did learn nothing ;-)

(2) Preset system. XML files.

(3) How to run a Jack application in an editor as a non-realtime
plugin?

(4) Kaiku should start as unconnected Jack application.
Or connected to Alsa or Jack ports given as command line options.

(5) My computer is only barely running Kaiku in realtime, and that
after I reduced the multitap delay complexity. I have not taken
speed-ups from LADSPA-GVerb.

Uh oh. The code has unused old code as well. Some experimental GUI
stuff. Ignore them.

I only would like to have a Lexicon quality reverb. Designing
and coding such a reverb is a huge task, and it won't help if
I spend years with basic software engineering tasks which any
Joe programmer could complete easily. My private Lexiclone
has several algorithms of which only GVerb has been turned to
open source within four years.

I'm not a reverb designer or DSP engineer either, and I'm not
sure do I want be one. I started figuring out the reverb business
with zero DSP knowledge, and only because we did not have
a quality reverb -- I wanted to change the situation.

Could we collect $$$$$ of money and hire Dattorro or any other
qualified effect guru to design quality open source effects for
us? Blender was purchased for $100,000, right?
