Hello list,
I've been going through the options available in qjackctl, and also
the options mentioned here: http://www.djcj.org/LAU/jack/. I've
noticed two options:
soft mode
-a (ASIO support)
What's odd is that neither option is mentioned in the other's doc.
For example, I cannot find a reference to ASIO support in qjackctl.
Likewise, I cannot find an explanation for soft mode in jack's doc.
Two questions: what is soft mode, and is ASIO support still supplied
and useful? One additional question: is there a place that provides
comprehensive explanation of jack's features and how to use them?

Here's an incredibly simple trick I discovered to synthesize incredibly
hard and groovy snare sounds... The typical THWACK that just makes the
crowds move.
You need nothing more than a noise source, one (yes one!) band pass
filter and a flexible envelope.
Hook up the source and your envelope and tune your snare with the band
pass filters cutoff frequency and bandwidth (also known as CF and Q-factor).
Then set up your envelope to have a "knee". If the volume graph for your
typical snare envelope looks like this:
| \
| \
| \
| \
|_______
Make it look like this
| \
| \
| \
| \
| \
| \
|_______________
The psychological effect is that the listener is 'punched' towards the
knee with great force, and then gently released, constantly keeping him
or her in that gentle musical trance place, while still being an
extremely man-moving sound. It's great to help induce that 'dance
trance' we pop musicians are all looking for for our shows.
Actually, you can get the same effect with an extremely strong
compressor; however, with this little trick you do the same thing and
use no extra CPU power.
Carlo
PS: ZynAddSubFX is a great way too implement this; use a Free-Mode
envelope and add an additional 'point' for the knee.

One very big reason for adding the soft mode was that alsa stopped
processing for a significant amount of time when alsa was not set to
ignore xruns. I don't know if that behaviour has changed now though. But
at least back then, soft mode made sense because you could get away with a
few xruns without hearing anything.
And because of this, it does makes sense to set softmode in realtime
mode, in case you are occacionally or continously close to running at 100%
cpu usage.
Hi again peeps,
So I've been having a ton of fun messing around with the various
sequencers, synths etc. available.
However, I've come against a wall, it looks kinda like this:
I want to be able to record a real instrument into Ardour (can already
do this) and then apply some LADSPA effects to it. *However*, some of
the plug-ins I'm using have two inputs, such as signal difference
plugins etc. and Ardour can't handle them. I've tried using omsynth
for this, but my poor Athlon 2000+ can't seem to handle om and Ardour
at the same time.
So if anyone has any suggestions as to how to proceed, they'd be most
welcome :) In particular, I'd prefer a graphical solution with a
Debian/DeMuDi package available.
Thanks!

Greetings:
My publisher, Bill Pollock, has been gently pressuring me to commit to
completing the 2nd edition of The Book Of Linux Music & Sound.
Unfortunately I'm in a precarious position to commit myself to the work.
The first book nearly wiped me out, I'm not sure I can sustain the
effort to bring the next edition to light. Nevertheless, I'm still
interested in seeing this book through to completion. So I have some
questions for the community :
1. Is there a real need for another book such as the The Book Of Linux
Music & Sound ?
2. If so, would I be wise to ignore the 2.4 kernel series ? (It would
make it easier to ignore material re: OSS/Free)
3. Would anyone be interested in co-authoring the book ? I've
considered offering some chapters to certain people on these lists, but
the issue of reimbursement gets sticky WRT royalties and other
compensation. I made very little money from the first book, but money
wasn't the true reward anyway, so perhaps there's a way to turn it into
a community-based work.
4. Is anyone else already working on such a project ? I don't want to
duplicate efforts.
Btw, this is the last hurrah for this project. If I don't take it now
I won't be taking it on at all. I have a life, it's pretty full, and
committing to this edition would be a major disruption. I can guarantee
that it would be the last book I'll ever write.
I look forward to your comments and advice.
Best regards,
dp
