| Summary | 0001855: Crash on Playback of Automation Data | ||||
| Description | Ardour 2.0.5 When you are playing back automation data on a track, and touch a fader, or several faders, that are on playback only mode, ardour crashes with an error about witing to port mcu: 0Success which I am fairly sure is not the right port;) Touching the fader in my case is necessary as for some reason, not sure if it is ardour or not at this point, some of the strips do not get updated like they should upon startup and do not update until they are modified. I tried switching automation to manual, and did the same procedure of touching all my strips upon startup, and did not have a crash, however when switching back to playback mode on the automation, it crashed again.

Ok I am going to have to take a look at this myself it seems, as I can't work any more on this session until it is fixed, SVN just crashes on startup. The console message is as follows... MackiePort::connect_any already connected MackiePort::connect_any already connected Surface: couldn't write to port mcu: 0SuccessSurface: couldn't write to port 0Success Copied over by hand, so while I was careful in my typing there may be a typo in there somewhere.

Uh yea I just realised I forgot to mention that the faders I reference are on the Mackie Control Universal Pro, so not in ardour itself. Though that is probably obvious from the error message;) Seablade |

Added some code to further reduce bytes that result in no change to the surface control, and an explicit check for write overflow which doesn't throw and exception. |
