Being a Piper I am very aware of intonation issues.
I tune my pipes to a scale of just intervals. The problem comes when playing with 12ET instruments.
The lower the pitch of the other instrument the better, if the instrument is in the same octave, beets can be a serious problem.
This applies particularly to the low G (actually Ab) which is a 7/4 ratio and a lot larger than a 12ET tone down from the tonic A (Bb).

All the best PP
