Dengizich, I'm also not a fan of Internet-dependent software, or any hardware that depends on a PC, tablet, etc., for full functionality.

Regarding Diki's post on the previous page... he's suggesting that you record the notes that trigger your chord changes to an external sequencer--either a DAW or a hardware sequencer. Quantize them, delete any false notes, and save as a Standard MIDI file. Then, play that SMF back INTO the arranger on the Note To Arranger "NTA" channel. (This are the MIDI channel(s) the BK-9 uses to control its style engine.) This approach will give you perfectly-timed chord changes with no glitches. With the external MIDI controlling the style, you'll still be able to trigger fills, variations, etc. Heck, you could even change to a different style mid-song! This approach frees your left hand from slavishly playing chords, so you can work the bender or comp with both hands if you have the skill to do so.

I have no doubt that this would produce a highly-professional result. The only downsides I can think of are that it's no longer 100% "live," so spontaneity is reduced (not sure how much that matters to you.) I also suppose if you mess up the part you're playing live, if your vocalist is late, etc., the MIDI driving the style will be like a runaway train; it might be hard to regain your place in the music. Features like Mark and Jump could provide a safety valve.

As I've stated before, I'm not a musician-- I'm a gadget geek who likes music. I perceive a spectrum of interaction from passive to active. For example: you can listen to .mp3s (passive). You can launch pre-recorded audio clips. You can play over a "canned" SMF. You can let a MIDI drive your style, as Diki describes. You can play "chords" (with one or more fingers) to control the style in real time. Most interactive would be two-handed piano, or perhaps a two-manual organ with bass pedals. There is no "best" approach. Only your goals and preferences, limited by your personal ability (and time to practice!)

A couple more clarifying comments... Am7 and C6 are comprised of the same notes. On Roland arrangers, even in Pianist 2 mode, the sixth chord is ONLY recognized in root position. You might force the display to show C6/E by sending MIDI to the NTA with an E bass on a different channel. However, I suspect the style will play back exactly the same as it would if you turned on Bass Inversion and pressed EGAC. In other words, the bass track(s) would play in E, and the remaining accompaniment tracks would play some combination of the four notes.

I have indeed devised a way using MIDI Solutions modules to make Bass Inversion a MOMENTARY function (as available natively on Roland's FP-series pianos.) It's on while the pedal is held down. I don't have to press a second time to turn it off. So it's very easy to use in real time for the odd slash chord, while playing other chords in any convenient inversion. I've observed that my beloved "one-finger" Major chords in Intelligent mode always trigger the root bass. This makes songs with slash chords easier to play, even if you leave bass inversion on the whole time. Also, one-finger Majors don't glitch or produce false notes; there's never a problem with notes added late because you only have to press one key! Remember, no one works harder than me at looking for the easy way out! :-)
