Baudline (http://www.baudline.com) is a fantastic viewer that does fft
cascade. I've used it for a couple of years, and it is great for figuring out
how different sounds "work", and it has an oscilloscope-type display as well.
I finally started making my pet music project and realized I need a
drum synth to make some cool sounds. psindustrializer is good but also
need some tr-909-style sounds. I remeber from my old windoze days I
used a nice piece of software called Stomper. Does anybody know any
software for linux with comparable capabilities? Or we need to write
Stomper does not work under wine :(
I had a couple of articles on drum synths. Check
I built the circuit in a00*.jpg at the time when this article
was fresh. The article b00*jpg mentions an earlier article.
I will check that out at library.
Hmm.. I coded a drum synth for Commodore VIC-20 at the time.
VIC provided an audio chip with three oscillators, noise,
and a common volume if I remember correctly. What I did was to
modulate osc pitch and volume parameters with a fast and accurate
(compared to Basic) assembly code. The drum sounds were assigned to
the keys. This was about 1984, inspired by Yamaha's digital RX drum
synths, not by analog drums.

Such "LAD Gems" doc would be much needed here too.
(For audio dsp gems, take a look at "musicdsp.org".)
I would appreciate if somebody would take a look at
Ardour and document best gems found there. E.g., the GUI
and audio thread separation and start up sequences.
Likewise for Linuxsampler and one of its GUI frontends.

Can anyone give me any examples of Free audio software being used by
Anywhere where it performs better, or simply doesn't cost two or more
body parts to use?
Quick answers get bonus points.

Regret to report I am having problems loading firmware for my multiface
again. This time I have the pci card in a 32-bit system running FC4 with
a recent 2.6.12 kernel and alsa from 1.0.10rc1, including
alsa-tools-1.0.10rc1. The error is:
Hammerfall-DSP: wait for FIFO status <= 0 failed after 30 iterations
Hwdep ioctl error on card hw:1 : Input/output error.

If Linux can't solve your computing problem, you need a different problem.

The site has a nice table of working setups, but no user emails. I'd ask

AFAIK, usb cards impose 48kHz (96), 48/3 buffer setup to please
everybody in the chain.
Jackd needs buffers to be power of 2, and usb-audio - multiples of 1ms.
> we consider the 192 kHz more as marketing gag :)
That's to compete with Fireface.

I meant light laptop. Better less magic 2.2 kg, where most of light but
powerful enough laptops are. Possibly with external CD.
And with price around $1500 in Russia.
Acer TravelMate 3002 looks good, has fast cpu, but shared video mem.
Sony VGN-S480 is cool (nv6200) but $2100. At least it exists.
The thing is, I can't afford 2 laptops - a powerful one and a light one.

Great! Are you using nvidia binary drivers?
Another set of questions for experienced Linux Audio Users.
Mainly it's related to laptop performace.
It seems the choice of video system for modern laptop consists of two
1) dedicated high performance controller (nvidia/ati) with closed source
2) shared memory controller (intel) with open source drivers
People on Windows forums (no choice for Apples) prefer dedicated
controller (with own video memory) because shared memory video degrades
performance and increase latencies (they say, and in windows).
I suppose, under Linux the things are different, because minimal
possible latency is directly related to interrupt processing: closed
source drivers have arbitrary interrupt paths, surely are written to
maximise video performance and thus, should play a bad role in latency.
Moreover they cannot be fixed. Open source ones at least can be fixed.
Or I am completely wrong and shared video memory makes it bad on a
hardware side (locking pci bus, for example)?
So, the question is: what to choose, integrated intel solution or
ati/nvidia one (in this case, nvidia is preferred, because of driver
P.S. As a target system, imagine laptop with RME Cardbus.
