Sounds like you had a very productive weekend!
I have Csound 3.49, (only recently) mounted on a 7200/90 PPC, 48Mb RAM, OS 8.1
and work exclusively in the non-real-time area.
Is there a way of reading data into a function table directly from a
pre-existing external ASCII file ?
If not, would you add it to your list please ?
Merry Winter Solstice to you,
Bob Douglas

Hello, and Merry Christmas, Happy Solstice, and
Happy Humbug to All,
I am an M360 troglodyte now in Csound.
All goes rather well except I have found that the
logical operators: '||' for logical 'or'
and
'&&' for logical 'and'
are rejected as illegal by the compiler.
These apparently have been changed from the codes in
the 1993 Manual in my possession.
On another topic, I noticed that the "soundin"
MACRO only is able to fetch a file typed "AIFF".
When I ask for it as a "WAV" file, it can't find it, so
something I'm doing is wrong.
Enough for now, and Luck to all,
Jeff Hall

Most timing things in Csound run at k-rate not a-rate. Unless your timings
are always exact multiples of a k-frame you'll find inaccuracies. Try
running with kr=sr and see if the problem goes away.

re
GEN23
This subroutine reads numeric values from an external ascii file
f# time size -23 "filename.txt"
The numeric values contained in "filename.txt" (which indicates
the complete pathname of the character file to be read), can be
separated by spaces, tabs, newline characters or commas.
Also words that contains non-numeric characters can be used as
comments since they are ignored.
All characters following ';' (comment) are ignored until next
line (numbers too).

It goes, in this example program (now tempo is 134.955), but unfortunately
it does not fix the problem in the real program. I still cant run two
instances of the sequencer instrument in synch... But Im using odd timings,
which might lead to some sort of round-off problems. I'll replicate the
situation in this example program, to see if that has something to do with
it.
Thanks for the tip. I really was implicitly assuming an a-rate timing, and
it was good for me that you pointed that out

Thanks Rasmus. I wasn't actually after a GEN that read into a function table
from an audio file, because that has been possible for some time with GEN01.
GEN23 is perfect for my needs because it reads in from a plain ASCII text file.
