hello list,

i have been working very little with csound lately and i really feel i'm
way behind all its incredible new features. actually, i still have to
catch up with features that have been around for years now...

now i intend to do some csounding again, and i'd like to do things a little
different from the "old way" i learned so many years ago. but i have so
many questions, that i need the help of the list...

let's begin with a simplified example. suppose i have two tables defined
with ftgen, and their table numbers assigned to global variables gisine
and gicomp:

gisine	ftgen	0, 0, 65536, 10, 1
gicomp	ftgen	0, 0, 65536, 10, 1, 1, 1, 1, 1, 1, 1, 1

the tables are later used by an oscil.

the question is, how can i chose from the score which table i want to use
for each note? i know i could assign the tables to static numbers, but
that's what i don't want to do. i have lots of tables and i would like to
address them by name.

thank you in advance from an old newbie,


lj

Hi,

ftgen:

gir ftgen ifn, itime, isize, igen, iarga [, iargb ] [...]

you can set the table nuber with the ifn parameter, you don't need to leave it 0 (or if you leave it 0, it means csound will put the number. Usually 101 for first table etc):

gisine ftgen 1, 0, 65536, 10, 1

gicomp ftgen 2, 0, 65536, 10, 1, 1, 1, 1, 1, 1, 1, 1

instr 1

itable = p4

asig poscil 0,1,220,p4

out asig

endin

;and later in the score

; p4 - table number

i 1 0 3 1

i 1 + 3 2

best!

hi luis -

i indeed think you cannot do this. the reason is that orc and sco are 
two completely different languages; so any gisine and gicomp which are 
returned by the ftgen statement are simply "not understood" by the 
score. (this is a bit similar to the discussion about the t-statement we 
had recently here on the list.)

i think there was also a discussion whether strings could be accepted by 
ftgen as names, like this:
giSine ftgen "sine", 0, 65536, 10, 1

if this were implemented, you could write in the score:
i 1 0 3 "sine"

and in the orchestra:
instr 1
S_table strget p4
aSine poscil .2, 400, S_table
etc...
endin

meanwhile, i think you could do what you want with the Stray UDOs i have 
written (https://github.com/joachimheintz/judo/tree/master/strays). but 
this implies including a lot of UDO code. if you are interested, though, 
i am happy to explain more in detail what i mean.

best -

yes, i know, that would solve my "problem". but that's what i was trying to
avoid, i wanted to see if it was possible/easy to leave the table numbers
to be assigned dynamically by csound, and refer to them by names. it's not
only nicer on the score, i think it also makes the code more portable
and/or scalable. but apparently it's not so easy, so i'm ready to forget
it. or i might define macros with names assigned to numbers or something
like that.

best!

hmmm, i was suspecting that much, really... i actually spent quite some
time fighting with this before writing to the list. 

i might be completely wrong here (i haven't used the string opcodes much),
but i think that what i need is an opcode that is the opposite of strset.
that is, something that assigns a number to a string:

	strseto	istring, iarg

i'd need of course the complementary strgeto, only that it wouldn't return
a string but a number.

then i could write (i imagine) something like this:


gisine	ftgen	0, 0, 65536, 10, 1

	strseto	"sine", gisine

itable	strgeto	p4	; in the score p4 is "sine"
asig	oscil	1, 440, itable

does that make sense?

Maybe this is a good use case to support dictionaries as a new built in type?

Cheers,
Andres

Yes. Like python or lua.

like wow, python-like dictionaries in csound would be an incredible
addition. 

i still think though that a pair of opcodes symmetric to strset and
strget would be handy on many situations.
