[Csnd] triglinseg error, I think

The Csound Mailinglist

Hey hey,
I noticed some odd behaviour with triglinseg. I used it in one instr. If I call the instr again, the resulting envelope doesn't seem right. Here's the relevant code snippet, a demo file is linked below:
...
aEnv = triglinseg:a(kTrig, .5, .02, 0)
Full code:

It only happens once the instrument is called again. Is that a bug or am I missing something?

Best wishes,

Jeanette

yes looks odd for me, too.
i thought it might be an issue in re-using the same instance, but i don't think it is the reason.
perhaps you file an issue?

Hi again,
I shall do so, when I get the desktop out and log in to github.

For the time being I have used lagud to create the simple envelope, which works very well.

Best wishes,

Jeanette

Hello,
where do I find some information about the triglinseg and lagud? Are they csound7 opcodes?

Hi Luis, yes they are both Csound opcodes. You can find them here:
https://csound.com/docs/manual/index.html

If you scroll down a bit, all the opcodes are listed in alphabetical order.

P.S. they should work as of Csound 6.17 or 6.18.

Hi Scott,

thank you. It looks like I was looking at the wrong manual. This works:
https://csound.com/docs/manual/triglinseg.html

but this doesn’t:

There was a fix to these opcodes a while back, I’m not sure it came before the last release. Are you guys building from source?

I’ll take a look, it seems to be in the most recent version…

10

I guess it’s just that the second manual page link is not working: it points to csounds.com, and that is probably not updated with the latest release

Many thanks Rory! -- I do run a release version. The package as it is in the ArchLinux repos.

Best wishes,

Jeanette

I pushed a fix, and your sample csd is now working fine for me. Thanks for reporting this :slight_smile:

Hi Rory,
many thanks for the super quick fix and the swift replies!

Best wishes,

Jeanette
