Any note groups of 2 or more notes will have swing applied (that means if you enter individual 8th notes there will be no swing.)
To change the degree of swing tap on the rhythm and choose Change Accents/Swing, then slide the swing slider.
Tapping on the Swing: label will jump to the most common swing options.
You can change the swing while PolyNome is playing so you can hear the changes.
Watch this in action…
