Volume Of Samples

If I load a sample on renoise and cooledit/soudforge/etc… I notice that renoise volume is lower.

Im sure that renoise lower the sample play level in some dBs.

How can I set renoise for get same volume as on external editors?

(I always have tracks/master channels renoise volume slidders to 0dB)

Adding a gainer on the mastertrack?

I have tested and renoise volume is -6dB (not sure… any developer can tell me if thats true?)

So if thats ok… adding a gainer on master channel at +6dB all should sound fine now?

yes, samples are -6dB by default, to leave room for overgaining.

A lof of VST instruments have that level by default, by the way
