 Re: [Csnd] Re: Re: Re: Re: Re: Deferred size not possible with GEN23?
Hi, Maybe it would be nice to review which opcodes can accept power of two tables which currently don't. Cheers, Andrés On Tue, Jul 22, 2008 at 7:16 AM, Victor Lazzarini < Victor.Lazzarini@...> wrote:
It's not about not knowing the size, but the fact that the tables are
non-power-of-two (deferred tables are always like that, even if they
are power of two in the end).

I just found that the documentation of GEN01 says you can only use deferred sizes with loscil units (probably just loscil and loscil3). I suppose it also applies to GEN23, although it is not mentioned there.
It's not intuitive. You'd think that the tables are read before the sound of any note is created, so the tablesizes should be known when they are needed.

Hi Mark -
as you said, this error is due to oscil, not to gen23. When you use the statement
gi_test ftgen 0, 0, 17, -23, "text.txt" (instead of 0 as size)
it works. Size=0 or any table length (also not 2^n or 2^n+1) works with poscil, or with the tab opcodes.

Here is a minimal example in attachment, based on your code, but with ftgen, although that makes no difference. I noticed that if I delete the note in the score, there are no errors, so the error is most likely generated when the table is used with the oscil opcode. The file test.txt contains 17 values, so it includes a guard point as required by oscil. CSound actually prints out that the table contains 17 elements, so reading in the file seems ok.

Subject: [Csnd] Deferred size not possible with GEN23?
Hi,
Now I ran into another problem with GEN23: the documentation says that if the specified size is 0, the size is determined by the number of values in the textfile. This would make what I want to do a lot easier, but when I try it, I get the error "deferred-size ftable 1.000000 illegal here".
I've had the same problem with GEN01, but then I could solve the problem by first determining the size with the filelen opcode. I don't know of a similar workaround for GEN23.
