My pleasure, Bobby. I too tended to hold onto an arranger through several model changes, preferring familiarity and mastery over a few minor additions each new model.

My whole arranger path has been only three instruments . G1000, G70, BK9. Over 28 years!

If you are willing to dig in, there's several ways that the already good styles can be improved. Firstly, virtually none of them use any of the 3 MFX insert effects! So that can make a vast difference. One of my favorite things is to replace distorted guitar sounds on the rock styles with clean guitar sounds, then run them through a proper MFX amp sim and dial up the crunch to about right. Now, just like a real rock guitar, the distortion is affected by what the guitarist is playing, not prebaked into the sound.

This works for live guitar work too... use the SN Jazz Guitar into an amp sim MFX, change the Chorus send effect into an echo (which you can make tempo dependent, so you can use the patch on a variety of tunes without editing the delay values) and the rock your brains out..!

Another well hidden function is the Key Audio feature... if you have a good audio loop library, percussion stuff, breakbeats, electronic stuff etc., you can import those .wav's to your USB stick and use them rather the same way you'd use multipads on a Ketron, or Yamaha/Korg. You can't use pitched loops (guitar strums, horn lines etc.) because there's no pitch tracking. But there IS a basic tempo adjustment so you're not stuck at one tempo using them.

If you're missing some of that SD1 'live drums' flava, this feature can bring some of it back. It's a bit clunky to use as the main drums (but the BK9's are very lively anyway) but for adding authentic percussion or modern breakbeat electronica to a style, absolutely killer!

Don't ignore your Control sliders... from adjusting MFX parameters on the fly (like phaser speed or echo depth) to playing around with synth sounds' resonance and cutoff for a modern 'knob twiddler' solo style, they can help you squeeze a lot of variety from one setup.

And lastly (for now), make good use of the fact that you can change Performances on the fly without interrupting the sound. Need more than one Performance to really nail two different sections? Not a problem. Almost seamless switching. If you DO hear any kind of hiccup it's almost always the MFX for a Part resetting.

If you plan your transitions, what you can do to bypass this is go from a lead sound on say UPR1 on one Performance to the next lead sound being on UPR2 on the next Performance, that way you don't hear the MFX clear its registry.

I've got songs I use three or four Performnces for, but with 999 entries in the Perf. List, you never feel restricted!

There's an amazing depth to the BK9, but little of it is at the surface. You got to dig a bit! 🎹🤩
