Depending on what's required I work alone or with different producers at the music production stage. This enables me to bring in skills when I feel they're required but keep things simple if I think that's how the track should go. If another producer is required or suggested, the fee for that producer may be different from mine.
I can produce music in traditional styles, or opt for more electro assistance to taste. Cubase and Omnisphere are my two greatest tools, but I also enjoy working with a wide variety of software and sounds.
