IIRC I did change the length of the clips by using the mouse. What I definitive know is, that some clips with offsets will have this effect: When I e.g. change the length of a note by mouse, while the grid is set to "beat", the note length won't snap to the grid, but for some ticks beneath the correct position. >> When in use with SynAddSubFx, Hyrdogen and JAMin sometimes the JACK >> connections were not correctly restored after an application crashed, was >> opened again and the song was loaded again by Qtractor.
