| Summary | 0000221: pan information not read when loading session | ||||
| Description | Version : Ardour/GTK0.430.2 with libardour 0.714.0 when loading a old session with for example one track hard panned to left, the track is visually center panned. I am saying visually because in fact there is no sound until the pan control is changed to a new value. pans must be set to "0,0". Similarly, if a "send" is added to a stereo track, this send don't work when this session is re-opened. Here it seems that the pan information of the send is badly included in the session file. I have included an example of the XML session file where it can be seen that the pans of the send redirect are "0,0" | ||||

I have investigate a little more this behaviour. When a track is really left or right hard panned it work. In fact when the .ardour file contains something like pans="1,0" or "1.5,0" or "1.9,0.9" the signal is panned to left. It seems that there is somewhere a cast to integer of the pan value. That would explain why classical pan values ("0.xxxxx,0.xxxxxx") are read "0,0" !!! |

The bug was cause by the atof dependency to locale in the function IO::parse_pan_string in libs/ardour/io.cc. This simple patch correct the bug !! : > diff -B -u io.cc.old io.cc --- io.cc.old 2004-01-16 16:45:14.000000000 +0100 +++ io.cc 2004-01-18 15:47:59.000000000 +0100 @@ -1583,7 +1583,7 @@ pos = 0; opos = 0; pans.clear (); - + setlocale(LC_NUMERIC,"POSIX"); while ((pos = str.find_first_of (',', opos)) != string::npos) { pans.push_back (atof (str.substr (opos, pos - opos).c_str())); opos = pos + 1; @@ -1592,7 +1592,7 @@ if (opos < str.length()) { pans.push_back ( atof (str.substr(opos).c_str())); } - + setlocale(LC_NUMERIC, ""); return pans.size(); } |
