Vertical pinch not working in wave Editor

[seachord]

Have just purchased Auria, and and going thru the various tutorials. Running on an Air2/64G with iOS 9.0.2

Currently I can't seem to control the vertical size of the tracks with a two fingered pinch. Horizontal works fine - just wondering this is is a current 'issue' or I've missed something. Vertical pinching is just plain ignored/non-responsive.

There needs to be more than one track present in the editor. Are you trying to pinch vertically with only one track?

No - there are two stereo tracks. Both the same clip imported via audio paste.
I just took another look - the two stereo tracks fill the iPad Air screen, and won't scale down. I've seen vids where there are many more tracks showing.

That's as far as you can zoom out with only two tracks. The more tracks you have, the more you can zoom out. Zooming in should be possible though in any case, up to the point where one track completely fills the screen.

Ok I guess what is happening is Auria is filling the screen with the two tracks. I added two more (for a total of 4) and the tracks get smaller, and vertical sizing now works/makes sense.
