musicforyourday, Bill... I doubt you'd be into the same stuff I tend to do, and my sequences tend to be VERY minimal. I try to play as much as if I were in a full band with no tracks, so the files tend to be mostly bass and drums and maybe some rhythm guitar...

Not what most people prefer.

musicforyourday, I would start to spend a LOT of time working with your older files and the Makeup Tools, especially the drum kit edits, the new guitar and bass sounds, with especial attention paid to adjusting the velocities up or down to make the Tone get the most out of the different velocity samples, then adjust the volume to re-balance it. Also, you can get some great results using the per-drum EQ... Toms and side-sticks sound much better with a bit of boost from mid or low band EQ.

Don't forget you can now, instead of using a wanky sampled distorted guitar, you can change the sound to a clean guitar, and then run it through a variety of amp simulators and distortion effects to get a far more realistic rhythm guitar. Plus this, when you use the new Dynamic Arranger, these guitars hit the amp harder or softer depending on how you play. This can sound amazing, if you dial it in right. And you have THREE MFX insert effects JUST for the Song or Style Parts! That means you can have different amps on different guitar Parts, so they don't clash...

There are a ton of possibilities in the BK-9. I am getting some fantastic results with some of my older files and styles, and I haven't even scratched the surface yet.

Just do yourself a favor, and either turn OFF or at least dial down the Mastering EQ and Compressors... Try to get the sound you want from the style or SMF itself, and leave the Mastering stuff just as slight smoothing or room compensation usage. On the whole, I find the factory presets a bit too aggressive, and you end up with an overhyped, slightly squashed sound. Maybe that's OK for you, but I'm trying to get the MOST dynamics out my arranger, not the least!

Hope this helps.
