Like the original Numa Organ, Numa Organ 2 version uses exclusive modeling technology (without samples) and is a pure organ, without pianos, music, synths or other sounds of any kind. Its controls look identical to those featured by the predecessor, but got a more compact package. It is made of metal. In addition, like the original, Numa Organ 2 offers 3 multitimbral parts: upper, lower, and bass pedals, which interact via MIDI channels 1, 2 and 3 respectively.

The 73-note keyboard is excellent and fast in action. Dynamic Touch has 3 modes: on, off and blinking, which correspond to the MIDI control of only internal sounds/only external sounds, or both. The instrument has knobs for adjusting the effect of overdrive, reverb, key press which remind of Korg CX-3 from the 80's. A small drawback of Numa Organ 2 is that in addition to selecting different models of the organ, it is not possible to change any settings.

By the way, as for the models, Numa 2 has several kinds of organs that can be selected by holding the Sound/Preset button until it starts blinking, then pressing one of them. Three models cover B-3, A-100, C-3 organs, and each of them sounds fantastic. Numa Organ 2 is very similar to its predecessor in capacity, "breathing", and in the quality of voices, even if they are mixed together.
In addition, in this version you can find a church organ and 3 transistors of combo-organs. The basic sound of them is quite authentic, but each model of the organ in the instrument uses Hammond 9 drawbars. With this organ, you can reproduce convincingly the compositions of such bands as The Doors and Animals.

Compared to Numa Organ 1, the second version features more obvious improvements of the overall audio authenticity. It is more open and less boisterous. The overdrive behavior was improved as well. In the original version it was more effervescent-like, but in Numa Organ 2 it became warmer bringing that tube feel.
