Default 1/2 tempo MIDI stretch?

So I started the track at double the tempo 120 that it should be and I mapped out my drums, but when I switch to 60 and stretch the MIDI items in half, it gradually falls off tempo. Why is it doing that?

It starts fine and slowly gets off tempo by a large amount at the end.

Still trying to shrink a MIDI item uniformly instead of tight on one end and loose on the other.

don't what happened to your midiitem

gradually transition tempo in midi items can be achieved when using tempomarkers.

I took all the tempo changes out and it still has the gradual thing going when I shrink it down.

I assume by "stretch the MIDI items in half" you mean you ALT+dragged one edge until the MIDI item was half its previous length.

I'd bet good money that you just went over/under half. For example, you go the right-edge of your clip, grab it, the measure indicator there says "16", so you drag it back to "8". All good, right? No, you just turned 15 measures into 7 and it's going to drift off tempo.

One way to be sure you've got it exactly in half is to watch the "speed" indicator in the tooltip and make sure it lands on exactly 2. In most cases this should also correspond to a snap location on your grid (unless you've done something funky, like have a partial measure).

Very interesting. I'll have to try that.

How about

SWS/FNG: Time compress selected items by 1/2
SWS/FNG: Expand selected media items by 2
