Hey Seth,
For most of my music, I like to play in C Minor – that’s just because that piano scale is most comfortable for me, and I can improvise easily.
EDM benefits from what is called syncopation. It when your notes play off-beat, yet are still on beat!
In addition, sound selection is a big part of one’s sound, and also makes mixing easier.
In terms of style, do you mean what VSTs would I use?
