Hi
I can't answer your question.. but this email has answered one of mine,
and I have successfully edited my asound.conf file to be able to do what
you are doing.. recording in through discrete channels and outputting
though discrete channels..
Maybe someone on the ardour list can answer us both by confirming that
this will allow multichannel recording on ardour (a possible solve to
the question I think you are asking)
cheers
Allan
P.S I'm still working on a way of then combining my Delta66 with my
intel8x0 (built-in to MOBO) so that I can use the stereo out of the
intel8x0 for monitoring while using the outputs of the Delta66 for
channel recording. (i.e. sending output into the mixing desk to use
outboard processing gear or for external mixdown of tracks)
cheers
Allan

Hi, I've been playing a lot with bristol synth and really love it. So
much so that I've been trying to 'Jackify' it. Actually, I'm pretty
much done, but can't figure out the internal audio format. Its
interleaved floats I think, but not normalised to [-1,1]. If any of
the developers are here could you help me out? I can hear noise, but I
need to tune the maths. TIA.

This synth has a mainboard running Linux inside :)
Seems like not only Stanton (Final Scratch) is relying on
Linux in the pro audio world these days ..

Hello
A friend and I have made a VST plugin as a college project, and would
like to open source it, and possibly port it to other plugin APIs. We
are considering the GNU GPL for our licence, which has lead to this
question: Does VST count as a special exception of being "anything that
is normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies the
executable," or should we follow the suggestion about [1]controlled
interfaces in the GPL FAQ?

Hello. I found an interesting paper on intervention schedules.
The author Curtis Abbott worked at Lucasfilm and the paper
is only one of the series of papers written by them.
Their system had multiple DSP processors and multiple control
computers with automation. We are doing similar real-time system
in software.
In any case, the paper is at
"http://www.funet.fi/~kouhia/abbott-ischedules.tar.gz"
for a couple of days only as I'm not the copyright owner.
Anyone has the following papers. These are also related to
my search on prior-art for so called Gigasampler patent.
IMHO, we do not need prior art for caching (and keeping) the
first part of each audio clip to memory, but there are people
who are willing to weaken their open source software volunteerly.
