** ISSUE ** The large panner window (edit from the menu or double click) Should be labelled the same as the track that it is from. |

ISSUE -- fixed in 3.5-256-gabb75d4 Panner default-values need rework. Invalid default values when panner-type changes. Switching to balance -> 2in2out, retains position from balance but (previously set) width can be invalid. current workaround: "reset" 2in2out. Similarly moving from 2 to 3 channels should retain the position relative to previous speaker setup (currently a 90deg shift is needed) Shift-click reset on automation-sliders for elevation and azimuth does not correspond to "reset" for VBAP, either. |

VBAP Panner GUI - the 'Diffusion' spinbox should be replaced or removed Pptions: * allow to drag speakers to set diffusion (but what if diffusion == 0, no handle) * replace it with a slider * or replace it with a dial Current issues with the spinbox (and why it should go): - numeric-entry is not supported in spinner -> global keyboard grab - spinner is integer only - rounding is not identical to automation-faders - it looks ugly Maybe actually the complete VBAP GUI should be re-done. currently there's no negative elevation, either. |

Issue -- fixed in 3.5-256-gabb75d4 If the stereo panner is edited and it's changed to equal power stereo, this causes the equal power stereo panners width to go outside of the box and be uneditable. |

ISSUE - fixed in 3.5-262-g79b56b1 (PS. also affected stereo-panner width) Strange behavior with vbap diffusion automation. Observations - You can use the slider on the automation track to go from -100% to 100% diffusion but when you draw in the automation, it only covers 0% to 100%. If you use write mode, it will show allow you to write automation from -100% to 0% but this automation goes out of the automation lane boundaries, which must be why it can't be drawn in. I am using the master branch so not sure if this is just an issue there or also with the cairo canvas branch. |

ISSUE - fixed in git-5396459667 If a stereo plugin is added to a mono track, the panner changes to equal power stereo. Right clicking this doesn't give you the option to change to stereo balance, like normal stereo tracks do. If the session is restarted, then you can right click and change between the panner types on mono tracks with stereo plugins but this doesn't happen unless you restart the session. |

ISSUE - Stereo width of aux bus sends is infinite if track panner is changed to stereo balance. Steps to reproduce - Add a stereo track and bus Add an aux send to the bus Change panner type on track to stereo balance Double click on send The aux send panner will be set to equal power stereo. If you change the width of the panner, you can go past 100% and there appears to be no limit. |

@Leatuspenguin regarding comment 0015579 This only relevant for linked-panners (right click on the send > send options > link with route; the default for new sends can be set in Edit > Preferences > Solo/Mute > Routing options). There are various known similar edge-cases. When the panners are linked, the panner on the send is /slaved/ to the one on the route itself. It receives the same value but cannot influence nor constrain the range. If the 'master' panner does not have a "width" control, "width" is unlimited for the 'slaved' panner. This is a tough, non-trivial issue and likely a wont-fix for the foreseeable future. An other variant (also with linked panners): Mono track 1 in, 1out. but a send to a stereo-track: The send's panner is not constrained. A workaround would be to not allow panner-linking if the types are different.. |

TODO: Disable panner on master-bus by default. |

Use degrees (rather than percent) for stereo panner & VBAP 100% means: both channels are 180° away from the actual panning position. Instantiate to 60° width, which translates to 100% stereo, and makes sense for vbap. |
|
|
**ISSUE** race condition? When panners are linked: remove aux send, recreate -> channel panner is reset. |
|
|
automation is broken (and has been for at least two years): write, touch, and manual all work as expected, but on "play" the sound is muted altogether. update: turns out the relevant function (distribute_one_automated()) is not implemented in vbap. "touch" only works on the first invocation, any subsequent run mutes the audio, too. |

the width and position parameters for the 2in2out panner are mutually dependent and will influence each other's range of legal values. that creates lots of hairy issues with hand-drawn automation, midi controllers and so on. rgareus suggests to make width := percentage of legal range. e.g. if position is all to one side, the image is mono even if width==100. probably the sanest option. backwards compatibility of existing sessions?? /me thinks the 2in2out concept is broken anyways (will only work correctly for pan-potted stereo or XY, not for any spaced microphones, which are used by most sample libraries). should be a special case rather than the default. stereo balance is a safer default unless the user knows exactly what s/he is doing. |

added screenshot to demonstrate problems with value interdependence. the automation was created by moving the panner faders in the editor window with the mouse, one at a time (no concurrent editing). |

here's a series of screenshots to demonstrate the comb filtering from reducing the width with the 2in2out panner: http://stackingdwarves.net/download/comb_filtering_demo/ (see README for explanation of the test setup) |

When i open new session, all stereo panners can be moved out of the box - signal can be amlified thousands of times (as long, as i can move the mouse left or right). When i switch type of the panner to stereo ballance and then back to equal power stereo, it works OK. This issue is from 3.5.308 until now. |

re comment 15686: I cannot reproduce with 3.5.357. open ardour, create new session, add 1 stereo track. Panner behaves just fine (there was an issue earlier in 3.5.3XX) possibly relevant settings: (here) * Preference > Solo/Mute > Link Panners is enabled (default) * Preference > Audio > Auto-connet enabled outputs to master * No monitoring section in session Do you use any control surfaces? Midi bindings? Do you still have this issue with the 3.5.357 release? |

0015687: You're right - in NEWLY created session, i don't have this issue. This is probably something strange in the concrete session definition. I thing, you can forget this issue. Ardour - compiled yestarday from git. Screenshot - http://pedro.propsychology.cz/panner.png forget it, sorry. |
