Ohh lala! What a woman! She can play piano (while her hair falls in front of her face and still play it like nothing happens). Can take good pics. Can fly airplanes, and owns a cat! I think we were made for each other. We should marry Thursday next week. ;)
Out of joke, have you thought of playing with orchestra plugins to create realistic symphony compositions? These may require a PC, but you can create a whole orchestra that sounds like the real thing.
An acquaintance of mine used to do this, and the soundtracks he created were so real it fooled me many a times. I can't remember the name of these plugins, but there are several types made by a bunch of companies, some good, some are amazing. Some packages contain like 900GB of sound recordings that can be inserted into tracks, to create your own compositions. If this interests you I can try to find the name of the software package he used. You may find yourself glued to the keyboard all the time with this.
Keep it up
