The included sizes for the Tenor patch in Originals Drumline is 14", 10", and 6". One can easily emulate other tenor drum sizes by adjusting the master tuning by 2 to 4 semitones in a second plugin instance.
In the example below, one instance is set to the standard tuning while a second is increased by 3 semitones. As the patches increase in pitch, this gives an emulation of smaller tenor drums as a result, shifting the 14", 10", and 6" drums to 12", 8", and 4".
Note: Holding shift and dragging the master tuning control will allow for finer adjustments.
