[Ardour-Users] automatable tape-recorder like playback speed?

[. m u r m e r .]

aha! yes indeed! i was only using the percent field in the pop-up 
window, i didn't try dragging with the mouse at all. as you say, if i 
drag the region end with the mouse (and then of course set the 
'contents' to 'resample without preserving pitch' when the pop-up 
appears), *then* the pitch lowers. fantastic! so i guess it is indeed a 
bug, but one at least with a very simple work-around.

best,
patrick
