|Platform||Librazik 3 (Debian 10 based)||OS||Linux||OS Version||(any)|
|Summary||0008646: looping can make the time cursor going backward while the sound is played forward|
|Description||When the speed control have been used to play backward, loop playing make the time cursor going backward from the loop beginning while sounds are played forward in a apparently random speed. The loop playing stop when the cursor reach the project beginning.|
|Steps To Reproduce||- open a project with audio track(s)|
- place loop markers. beginning of the loop must not be at project beginning and should be placed in a noticeable place ( beginning of an instrument part for example)
- place the time cursor anywhere except at project beginning.
- use the speed control to play backward and release it
- click "play loop" button or press the "L" shortcut. The cursor goes backward while the sound is played forward with a speed that depend on the previously used speed on the speed control
|Additional Information||Reproduced in the last official demo version.|
I join a project for convenience
Loop goes backward_2021-03-31_163244.ardour-session-archive (169,045 bytes)
An additional step to reproduce this: Play backwards first, with vari-speed dial in "wheel" mode. Ardour remembers the previous speed and resumes playback with the given speed.
However transport-control is backwards, but playback buffers have forward data.
You can work-around this by resetting the speed to 100% (context menu of the vari-speed slider, or shift+click).
||@x42, i don't need your additional step to make it happen. I mean, i make it happen with vari-speed set in sprung mode. I'm going to test your variant thought, i just experienced a crash few second after have been tryed it once,|
||I guess you have previously rolled backwards (ardour remembers this in your local prefs). When you press play (no loop) which direction does the playhead move?|
when the varispeed is in sprung mode doing:
- open the project (i tried to use my archive but i don't know how to open it)
- set varispeed to a negative speed and release it (playing stop when i release the mouse button)
at this step two possibilities:
one, I "loop play" : the cursor goes backward, sound played forward, and i didn't noticed before, the varispeed goes back to the previous negative speed
two, i do a normal play : the cursor goes forward, sounds are played forward and speed is 100%
i found another bug, probably related and more annoying, i'm going to publish it

In Session > Open file-picker dialog you can select session-archives. They are then unzipped to the default session folder.
Alternatively you can use `tar xvJf the-archive-file` - the files are really LZMA compressed tar archives.
