Package: ardour
Version: 1:4.7~dfsg-1
Severity: normal

Dear Maintainer,

It is possible to set invalid balance values for stereo bus sends in ardour4.
How to reproduce: add a stereo bus and an audio track to your project. Add a "New aux send" to your audio track, open mixer window.
Click the 'Aux' button on you bus to show aux send's volume and balance parameters on the audio track. On the audio track grab
either the (L) or (R) signs to set stereo with or the center indicator and move it out of the channel strip.
You can set stereo width over 100% and L/R values below 0 and above 100  (eg: L: -70 R: 170 Width: 145%).
It will cause false stereo image rendering.
