A first release of Yass is now avaiable at
<users.skynet.be/solaris/linuxaudio>.
Yass is a 'scrolling scope' jack client. It has been
hanging around in prototype form for some time. This
is a first beta release.
Main features:
- up to 32 channels,
- variable scrolling speed,
- configurable trace colors,
- automatic gain control,
- very light on CPU use.
Enjoy !

Thanks!
Got one problem though: high CPU load (I'm not kidding). At small window
sizes everything's fine, but when it exceeds a certain size (a little
less than fullscreen on my machine), CPU load immediately goes up from
~5% to 100%, drawing starts to lag behind, and X becomes very sluggish...

How much is fullscreen or your system ? This looks like insufficient
pixmap space on the X-server.
I've noticed another lock-up problem: yass stops scrolling and
takes 100% CPU. Happened once here after many hours of running.
The two may be related.
Here is the real .yassrc:
% Configuration file for Yass
% Everything in this file can also be put in a system-wide
% configuration file '/etc/yass.conf'.
%
% Instances started with -name NAME will read '~/.NAMErc'
% instead of this file.
%
% The same options can also be put in '~/.Xdefaults', and
% will then apply to all instances started by the same user.
% Default number of channels and connections.
% Modify as required

Fullscreen would be 1280x960, problems start at roughly 1000x900 or
something. But even at somewhat smaller window sizes, just slightly
resizing the window causes an increase in CPU load for up to a few
seconds. Drawing then lags behind for a while, but eventually catches up,
and CPU load goes back to normal.
An then, when I increase the window size a little more, somewhere it
reaches the point where it just never catches up, and eats 100% CPU
indefinitely.
