| I have a Pentium-200 running windows'95, with a SB Awe64. I downloaded
the file:
ftp://ftp.maths.bath.ac.uk/pub/dream/platforms/pc/Csound 3.47beta.zip
and read the tutorial. I read the FAQ too. What I read seemed straight
forward, but it still
left some unanswered questions. I made the files "intro.orc" and
"intro.sco". I copied from the
tutorial, so for "intro.orc" I have:
sr = 20000 ; audio sampling rate is 20 kHz
kr = 500 ; control rate is 500 Hz
ksmps = 40 ; number of samples in a control
period (sr/kr)
nchnls = 1 ; number of channels of audio output
instr 1
kctrl line 0, p3, 10000 ; amplitude envelope
asig oscil kctrl, cpspch(p5), 1 ; audio oscillator
out asig ; send signal to channel 1
endin
and for "intro.sco" I have:
; a sine wave function
f1 0 256 10 1
; five notes at once
i1 0 3 0 8.01
i1 0 . . 8.03
i1 0 . . 8.06
i1 0 . . 8.08
i1 0 . . 8.10

With these files in the same directory as my csound exe's, I do a:
csound intro.orc intro.sco
and for output I get:
SFDIR undefined. using current directory
Then it prompts me to view the graph, and then displays that ok. Then
it says
something like:
0 errors in performance
49 2048-byte soundblks of shorts written to test.
I check, and there is indeed a new file named "Test", but without an
extension.
The next instructions in the tutorial say to do this to hear the output:
play test
That gives me:
Bad command or file name
To verify, I see there is no "play.exe" or anything of the sort in any
of my
directories.
The command:
csound -o devaudio intro.orc intro.sco
writes it to a file "devaudio" instead of directly to my soundcard. I
read that
my Csound module has to include user access to the audio output device.
Anyone know how
this works on a PC with a sound card?
Here are my questions:
1) Is there an install procedure for the PC, assuming I want to run it
from
the command prompt in my DOS window? Do I have to set path,
environment
variables, etc?
2) Why can't I do the "play Test" command? Am I missing a file, or is
that
command only valid on Unix?
3) How do I set up my user access to my soundcard so that "devaudio"
will work?
4) How do I convert/save my music I generate to a WAV file?
5) Why does running csound.exe at the command prompt make my monitor
screen
go about 50% dimmer until I reboot my machine?
CSound looks really awesome and powerful from what I have read so far.
I am
willing to go through the effort of learning it, as I'm sure it will be
worthwhile.
If anyone can help me by answering some or all of these questions, it
will be greatly
appreciated.
