Hi, On last csound cvs and UbuntuStudio 9.10 32b When i use duplex stereo with jack, i have the message : *** rtjack: input and output parameters are not consistent and csound stops. Csound jack in duplex mono is ok. Is somebody can tell me what are the new parameters to add to have a csound jack working as before? Thanks, René |

Hi Rene, I think John added a feature to have a different number of in channel than out channels recently, and I think to set the in channel number one uses: nchnls_i = x where x is the number of input channels. Could you try setting that value and seeing if that works? steven On Sun, Mar 21, 2010 at 4:14 PM, Rene Djack |

So is nchnls_i corresponding to the internal variable inchnls?

I am not sure as I only encountered nchnls_i in terms of the parser. I did a quick grep and in musmon.c it looks like it assigns the value to O->inbufsamps and otran.c has p->nspin set to p->ksmps * p->nchnls_i. John can hopefully enlighten us on this topic (perhaps better on the dev list if it is technical). On Sun, Mar 21, 2010 at 4:26 PM, Victor Lazzarini |

Previous;y top 5.12 the number on ins and out had to be the same. i added code to separate them, but it was not activated until after 5.12 Prelim=inary tests doid not show any problems, If nchnls_i is not set it is supposed to defai;t to nchanls but I anm not cerytain that this is checked in all cases I have never used jack (and am toytally unclear what it would do for me) so I ould nit have noticed ==John ff > So is nchnls_i corresponding to the internal variable inchnls? > yes Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" |

Maybe you should try testing with Jack. It should not be difficult to build and install it, then run jackd. You will need to then run -odac:alsa:playback_ -idac:alsa:capture_ or something like that (I forgot exactly the connection names to physical devices on linux) Victor On 21 Mar 2010, at 20:35, jpff@cs.bath.ac.uk wrote: > Previous;y top 5.12 the number on ins and out had to be the same. i > added > code to separate them, but it was not activated until after 5.12 > > Prelim=inary tests doid not show any problems, If nchnls_i is not > set it > is supposed to defai;t to nchanls but I anm not cerytain that this is > checked in all cases > > I have never used jack (and am toytally unclear what it would do for > me) > so I ould nit have noticed > > ==John ff > >> So is nchnls_i corresponding to the internal variable inchnls? >> > > yes > > > > > > Send bugs reports to the Sourceforge bug tracker > https://sourceforge.net/tracker/?group_id=81968&atid=564599 > Discussions of bugs and features can be posted here > To unsubscribe, send email sympa@lists.bath.ac.uk with body > "unsubscribe csound" > Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" |

Hi Steven, Magical, I just add nchnls_i = 2 and jack is happy and me too. Thanks a lot, René 2010/3/21 Steven Yi <stevenyi@gmail.com> Hi Rene, |

I guess this should be adjusted so that if nchnls_i is not present, it defaults to nchnls (otherwise we will have broken backward compatibility). Victor On 21 Mar 2010, at 21:23, Rene Djack wrote: Hi Steven, |
