Apart from the low trigger point, the Numa works perfectly as a controller for the module. With some slight differences, all the knobs drawbars and buttons do as they usually do, plus if you select the split button with octave up, it gives you another octave for the lower manual on the reverse keys.As the Numa has the KeyB engine, you just select that option on the screen. There are over 70 parameters selectable from the screen so you can fine tune everything to suit and save with one button press. Unless Diversi are suppying one, there is no power unit with the module ,so you would have to add that to the price.
