<p>SpiritManager, I understand the spirit of your advice but I am not going to use MIDI recordings. I am using virtual instruments - that is, plugins. These are sampled instruments which, to an unitiated ear, sound exactly the real thing. I will definitely record myself playing my piano compositions. I have access to a Yamaha C3 Grand where I work, so I will have at least one beautiful (real recording). For the harp piece I may be able to find a harpist, it should be easier than arranging an ensemble. I am keen on displaying a sense of knowledge about my instruments of choice - so the performance aspect is very important. If a piece can’t be played comfortably or with the proper expression it is a lost effort.</p>
