 Even though the instrument was awarded numerous prizes for innovation it was difficult to operate due to its limited display capabilities, which made adjusting the tonal qualities of a sound a tedious trial and error process.Given the very high price of the instrument (around 5000 USD) many people felt that manipulating a wireframe model of a sound only by ear did not allow for the amount of control necessary for such a complex operation.However, combined with a sample editor, the included Modelmaker software & MIDI control via sequencing, this difficulty can be somewhat rectified, albeit without the aid of the 3D image of the model.
