Summary0002556: Cannot draw midi notes. Ardour crashes on mouse button release.
DescriptionUsing the pencil midi tool crashes Ardour when drawing midi notes.

ardour-3.0: libs/evoral/src/Note.cpp:41: Evoral::Note<Time>::Note(uint8_t, Time, Time, uint8_t, uint8_t) [with Time = double]: Assertion `length() == l' failed.

But only when the midi track is zoomed out vertically using the scroomer.
Steps To Reproducecreate a new midi track. Create a new midi region with the pencil tool. Use the scroomer to zoom right out. Draw a note with the pencil tool.
TagsNo tags attached.

Hmm, doesn't seem to be fixed, I'm still seeing the same issue.

added a crash log file. I can't really give any more accurate reproduction instructions. It happens by following the instructions I've given already. If I do figure anything new out I'll let you know.

I had the same bug today. Ardour3 revision is 4647, just from SVN.
To reproduce it I have to:
- Create new project
- Add midi track
- Arm it for record
- Move transport somewhere from zero.
- Press record and play.
- Record silence on that track to create empty MIDI clip
- Stop recording.
- Try to draw anything inside with a note tool.

And I get the error described above. No zooming required.

By the way, for some strange reason playback doesn't start if transport is in zero position. If I move transport, playback and record works, but if I move transport back to sero, I press play or record, buttons are pressed, but cursor doesn't move and time doesn't go. Can anyone reproduce this?

Thank you, agorka. At least somebody knows what precise means ;)

I have reproduced this once out of clicking in literally hundreds of notes (the one time I wasn't in the debugger, naturally).

Does this happen regularly / every time? What are your snap settings?

I tried it four times, and each time ardour crash when I try to put the very first note. My system is Ubuntu Jaunty, I compiled Ardour3 with SYSLIBS=yes FREESOUND=1, because without syslibs I get error somewhere in gtk toolbar.
My resolution is 1024x600 (I try linux on a netbook for now), and Ardour window behave very crazy, jumping after every mouse click, so I have to put it somewhere off the screen enges to be able to click anything.
I have no midi ins/outs on this netbook so track input & output is disconnected.

I tried few times more now, and I was able to put 2-3 notes, and on the next one it crashed. Once it stopped responding after pressing add on new track dialog. Dialog disappeared but Ardour didn't react on any mouse clicks.

Snap was set default to beat. When I changed it to beat/16, I was able to add a few more notes, but crashed again.

And can you test the problem with transport I have?

I want to know what length() and l are at that point. When it crashes:

print length()
print l

lincoln

It is fainling at assert(length() == l); of the Note constructor.

looks like since it is comparing doubles were one (length()) is the result of an operation (off_event.time - on_event.time) and the other parameter is the passed in length value, that there is a precision issue?
