| Yes, David hits you people again with his restless questions..
It has been 4 to 5 years now (I was 17 - 16 years old then) that I"ve been
explicitly interested in experimental ambient & electroacoustic computer
music. During those years there is an odd thing that
kept capturing my attention : scientific soundengineers and researchers are
in most cases also
somewhat interested in spirituality....
My question is : is this true or false ?
(for me personally it is true)
David.

Hey there,
How can I let Csound calculate the amplitude of a score ?
I have an instrument that performs 5 times with (almost) same starttime at
different pitches, in
order to create a rich harmony. To do this I have to state the instr 5
times in the score file, each
for one pitch. But the problem is together they sound to loud and have lots
of samples out of ranges.
(I can calculate the overall amp manually...yes...but...)
Is there a way to calculate to final amp of a bunch of instruments at score
time and adjust the
amp of each instr at k-time ????
The files are named "brass" but actually they use a wgbow opcode. never
mind.
David.

Is thee proper documentation of the CROSS2 opcode ???
It is mentioned in the manual, yes, but does not say what the arguments
mean...
The manual says :
asig cross2 ain1, ain2, ilen, iovl, iwin, kbias
Cross synthesis between the two audio signals. (New in Csound 3.47)
I guess ain1,ain2 are the carrier and modulator waves...
- ilen = lenght ?
- iovl = ?
- iwin = ?
- kbias = ?
p.s. : can someone briefly explain how basic (kraftwerk-ish) vocoding is
done ??
I think it is done by filtering out a few harmonic partials of a wave
(someone talking) and use them to
control the volume of the according harmonics of the signal to be vocoded .
wrong ? right ?
David.

Hey,
would you *pleeeze* just paste & copy the scores
and orcs into your mail?? I fear: if attachments are used
generally, people start sending binaries, sound files,
Lady Di jpegs, complete csound sources, or those of other
programs and what else. If people are forced to use plain
text they are forced to concentrate on the important part,
which is good, I think.
Possibly, there are also people out on the list
whose mailers don't know much 'bout MIME types.
You can use "ftp" with your MS IE to transfer files.

Hi,
Is it possible within an instrument to extend the duration of a note? I am
designing a pipe organ instrument, for use with a MIDI file, and I would
like the release portion to begin after the specified duration.
And where can a Mac binary for CSound 3.47 be found?
Thanks,
Brandon
PS I would love to hear any pipe organ instruments that anyone has
designed.

You can set p3 inside an instrument. For example
p3= p3 * 2
in an instrument, will give you a durations for that instrument's notes
that are twice as long as that given by the score. I do this kind of
thing often.

I am no tester or whatever of the SHARC card. In fact I have

I would also like a hint about the SHARC card performance

If you are using MIDI in realtime, it is possible to use the opcodes
'xtratim' and 'release', new in 3.47 version (see the manual for more
details and an example).
If you use deferred time with score-triggered notes, it is very simple:
symply add to p3 the time of relase within the orchestra:
instr 1
....
p3 = p3 + releasetime
...

I have never really found this sort of comparison useful. Sure, if the
Pentium II could be used ~exclusively for sound generation, it might
well prove ~very fast, but in all instances I am likely to encounter, it
is saddled with running Windows95, NT, or whatever, and managing a huge
and demanding display subsystem. The SHARC card has, I trust, minimal
operating-system overhead, and can just get on with it.
