| Hi list,
thanks for the information about venice.
Before I travel I introduce the new version 1.1 of hYdra,
the editor for adsyn files.
It got a new spectrumeditor which can global adjust the volumes of the
harmonics which results in a filtering of the adsyn sound.
Also new is a native Win95 version which is dramaticly smaller as the 16 Bit
one and should be prefered.
Both can be found at

I have been working on creating a script that would enable a variety of
possible "patches" for a MIDI device. The igoto command and
conditional branching seem like they would be a large part of that. Here
is a script I put together as a test of the logic of igoto and conditional
branching (some of the comments wrapped in this email, but you can still
tell what's supposed to be a single line.) Trouble is it won't work:
The orchestra, "split.orc":
sr = 22050
kr = 441
ksmps = 50
nchnls = 1
instr 1
ipch=p5 ;if I integrated
MIDI into this, this would read "ipch=pchmidi".
if ipch<=8 igoto below ;jumps to the
"below" section if the key is below middle C
if ipch>=8.01 igoto above ;jumps to the
"above" section if the key is above middle C
below: a1 oscil 10000, cpspch(ipch), 1 ;produces a sine
wave for pitches below middle C
igoto sendit ;jumps past the
"above" section to the output statement
above: a1 pluck 10000, cpspch(ipch), cpspch(ipch), 0, 1 ;produces a pluck
for pitches above middle C
sendit: out a1 ;output, reached
by the igoto in the "below" section or reached naturally by the "above"
section
endin
And the score, "split.sco":
f1 0 1024 10 1 ;typical GEN10 sine function table
i1 0 1 0 7.06 ;chromatic scale from F# below middle C to F# above middle
C
i1 + 1 0 7.07 ;7.06 through 8 should output as sine waves
i1 + 1 0 7.08
i1 + 1 0 7.09
i1 + 1 0 7.10
i1 + 1 0 7.11
i1 + 1 0 8
i1 + 1 0 8.01 ;8.01 through 8.06 should output as plucks
i1 + 1 0 8.02
i1 + 1 0 8.03
i1 + 1 0 8.04
i1 + 1 0 8.05
i1 + 1 0 8.06
e
When I run this using Gabriel Maldonado's RTSound 1.8, a variation of
Csound 3.46, in conjunction with Riccardo Bianchini's WCShell95, I get
"This program has performed an illegal operation and will be shut down."
When I run it using Winsound, I get "INIT ERROR: pluck: not initialized."
I've tried all sorts of combinations, and it seems that when it skips over
a signal generator (which I guess it never TRULY does) it gets screwy.
Does anyone have experience using igoto? Any suggestions?

In fact, using igoto in this way, to skip the initialzation stage of an opcode,
will hardly ever produce satisfactory results (I can't see why one would ever
want to do it), and in this case, means that memory required for the delayline
is not allocated. On a performance pass, igoto is a no-op, and the opcode is
reached, whereupon it tries to access the unallocated memory. Without the error
traps, (many of which I added to Winsound myself, having found just this
problem!), the operating system will protest as you describe.
Are you using the latest version of RTSound? I would have thought these bug
fixes will have have been added by now.

Dear all,
Have you read Qian Chen's message on "Why Csound"? Is it true that we do not need to modify the Csound code and generate sound file on different platform?

I have experimented with using conditionals to check some variable and
change the output accordingly. I did this in another script where I
calculated a dozen possible outputs, and the "out" statement was changed
according to the value in my "patch" variable. I wanted to jump around
the initialization stage of the opcode because I figured by doing so, I
could calculate only one output signal and send it out, rather than
calculate a bunch and then choose one. I thought igoto would be an
efficient way of doing this. Would I be correct in assuming that this is
not the case? It seems from what you said, Csound doesn't work quite like
a typical programming "language" where you can jump around pretty much at
will without worrying much about memory allocation. Is it (paradoxically)
easier to create several signals and then output only one? I've done THAT
successfully, but it seems to my mind to be rather inefficient, especially
when dealing with more than 4 or 5 signals. Thanks for your help!

I want to be able to control which opcodes it reads and which it skips
through MIDI or some other real-time outside control, as in the split
keyboard example. Only one possible output at a time would be active, so
the other possible output(s) would be skipped. I didn't include any MIDI
commands in my example for the sake of simplicity.

You ~can~ use jumps, but try kgoto or plain goto. Actually, I can't think of any
'typical' programming languages which allow you to 'jump around at will', when
that means trying to access data you haven't created! Unless you have a lot of
processor-intensive opcodes in your instrument, it will indeed be more efficient
simply to run everything, and choose the output you want. In any case, the
initialization stage is rarely demanding (I can't think of any example of one
that is), so to avoid runtime costs, you are better off using kgoto or goto to
skip runtime calls to that opcode.
There should be no problem, or course, if you are simply choosing between
alternative versions of the same opcode at runtime.
The fact that there are three levels of Csound execution - initialization,
krate, and arate, each with its own form of jump, is one of the biggest sources
of confusion, especially for users who are familiar with general programming
languages, where a jump is always a jump. In Csound, a jump is only sometimes a
jump!
