Hi all,
I'm practicing with Cabbage to easily create a simple VST to use with an
external sequencer (e.g. Live, etc.).
I followed some examples from FLOSS Manual and, thanks to these ones, I
simply compiled an oscillator, with ADSR control, triggered by a MIDI
keyboard. Of course the project works correctly unless for the fact that,
when I trigger a MIDI Note, the output is a little bit noisy, particularly
during the attack phase. Now, I'm working on Mac OS X with a built-in sound
device (Core Audio), but the issue occurs also running the same project on
Windows with an external device (ASIO); so I don't think this is a sound
device related issue.
Then, what is the source of this issue? Can it be due to an inappropriate
"sr" and "kr" or "ksmps" value?

I attach the original .csd project and a sample recorded by CsoundQT:
Simple_Oscillator.csd
  
Simple_Oscillator.csd.mp3

Which version of Csound and what version of Cabbage. There seems to be
something funky going on with the OSX build. I can play your example
here without any problem with the audio. I'll check it on OSX later
and get back to you.

I didn't know Cabbage was so old :)
Pretty realistic sounds.

Something's got the funk, but I think it's the latest release of
Csound. I'm taking this over to the devs list. Btw, I can't install
the latest Csound on OSX, but the latest Cabbage with Csound6.00.1
works fine there.

I'm working with Csound v.5.19.02 and Cabbage v.0.04 (pre-beta version).
So, I gather that the actual "ksmps" value is enought and it's not the
reason of this issue, isn't it?

It does sound like a ksmps/stair-stepping issue.  Could you try using
ksmps=1, or using an a-rate envelope?

Ok, so it's unrelated to the issue with the latest Csound6. In that
case you can try Steven's suggestion?

Hi,

I was wondering if anyone can help me with some csound code for what
would make a good irreversible real-time voice changer?

Josh

Perhaps you could provide a little more info?

Yes, it was a sampling issue: I solved using an audio output from "masdr"
(originally I thought this opcode doesn't allow an a- output but only a k-
output). And as you can see, there are no more spectral components now
except for the two sinusoids reproduced. Thanks a lot, as usual.

Do you want the output to be understandable?

I would experiment with pvanal, killing some bins and moving some of the 
others.  Killing bins is irreversable; mixing bins also
==John ff

... but killing bins is ethically acceptable, as long as it's for a good cause

Guys, I don't know if you realized it but you are merging two different
arguments in the same thread on Csound forum...
Is it maybe due to a wrong e-mail reply?

John is obviously still struggling with his new mail server! Seemed to
fork with his reply.

Look at the nabble thread.

from here (using offlineimap to get my messages, and mu4e to browse
them) all "Noisy attack..." and "Irreversible real-time..." messages
appear to be mixed in the same continuous thread.

However, do not misunderstand; I mean I pointed this out not for my sake but
for the sake of the Csound users that - maybe in a future - will look for a
similar topic.
Best regards.
