Any idea why? If you look closely you will see that neither the treble nor the bass portion of the deviation curve is perfectly flat. It is just more noticeable in the bass. This is so because the tuning curve is continuous and it gradually transitions between the bass criteria and the treble criteria. If you are going for 4:1 double octaves in the high treble and 6:3 octaves in the low bass, then somewhere in the middle you will have beatless 4:2 octaves. Rather than trying to adjust the deviation curve to be perfectly flat all the way across, just try to adjust it so that it is flat at the extreme ends. Robert Scott Real-Time Specialties
