Mmm, I think there is a bug here :</div>

No matter what you type in the "percent" field, the stretching will use the mouse to choose the new pitch.</div>
<div style=" margin: 0px; font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; background-color: rgb(255, 255, 255)">

</div>
<div style=" margin: 0px; font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; background-color: rgb(255, 255, 255)">
That is : if you drag the right part of the region to twice the original size, the frequency will be divided by 2 (which is what we want in this case, could you try that ?</div>
<div style=" margin: 0px; font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; background-color: rgb(255, 255, 255)">
If you just click the region and edit the "percent" field, as the mouse hasn't moved the right margin of the region, the pitch will stay the same</div>
<div style=" margin: 0px; font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; background-color: rgb(255, 255, 255)">
If you "free drag" the right margin to anywhere between those two positions, the frequency will be adjusted accordingly.</div>
<div style=" margin: 0px; font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; background-color: rgb(255, 255, 255)">
<br>
</div>
<div style=" margin: 0px; font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; background-color: rgb(255, 255, 255)">
That sounds like a bug, can you confirm that ?</div>

i'm running ardour 5.12.0 on a macbook pro (el capitan). maybe it's a <br>
version issue?<br>

thanks for helping me sleuth this!<br>
