Hi, you could use Ctrl+Alt+e on the sample file in the browser to double or halve the BPM. However, this probably wouldn't help when playing a sample from the sampler slot.
You can try different sync settings for vdjsample files.
Mallmuzik/sample files/sample bank editor
Press 'O' to open an existing bank.
Press 'Shift+O' to change the slot settings. (This only works if the file is in .vdjsample format.)
Tempo Play Mode: Sync Start
