the select tool

lets you select and move (transpose or move in time) some of sounds in your piece.

In all cases, holding the shift key while dragging locks the current pitch. This means you can move sounds earlier or later without risking changing their pitch. Finally, dragging the selection when the pitch snap or time snap buttons are switched on will automatically make all the sounds snap to the current grid. This can be useful if you want to automatically transpose a piece in a different scale, but can sometimes have undesired effects of detuning some of the sounds.

hint: you can deselect all the sounds by clicking on the background and drawing a very small rectangle that doesn't intersect any sound.
