Montage after the render procedure help please

Montage done but in the render section how can i keep the volume level as i rendred each track alone ?
after the render procedure my montage track sounds very distorted
please help !!!

I guess you have changed the Master Section level by mistake?

My guess would be the track level (left to the audio montage waveform) is changed by mistake.

This used to happen to me now and then. Luckily, PG has included a setting to not allow the changing of the track level by the scroll wheel on the mouse. I think that when zooming in near the start of the montage, I would accidentally move the track level, and usually found out the hard way.
