I'm Nicolás Ocampo, I'm a composer, music and audio producer (editing, mixing and mastering), and academic copyist received at the Facultas de Bellas Artes, Universidad Nacional de La Plata, Argentina.
It would be to make an arrangement / reduction for piano of those three songs, no problem but we would have to establish well the length and complexity of the midi arrangements, since that will depend on the cost.
The midi arrangement can be basic (melody and accompaniment as small as possible) or it can be complex (all the superimposed voices and melodies arranged for the correct typing of a pianist). In both cases the midi will be written so that a pianist can play it with two hands
