If the style doesn't do what you want it to do, change it, Lucky...

If there are too many parts, mute them. If the dynamics are squashed, turn off the compressors. Turn up the drums, turn up the bass. Force yourself to compete with them (like you would a real drummer!). If they aren't good enough drums, import some samples (if you have Korg or Yamaha or Ketron, etc).

Push comes to shove, if all I've got in my hands is a Yamaha, I figure I can probably beat it into shape... Maybe not the same shape as my Roland, but I can make it work for me (I even push bass and drums on my G70 compared to factory settings, and turn off all the compression... it's a disease, all this smashed up sound we are getting used to ).

But you are right, 90% of it all comes from playing it. Everyone has heard genius on a Casio, and rubbish on a T2, etc.. It's not the gear, until you are already playing at the highest level.

It's ALL you...
