Seems that all companies have been concentrating on different parts of the arranger in the last few years..
Roland have been concentrating on creating cheaper good sounding arrangers.
Yamaha has been concentrating on top knotch solo voices
Ketron has been concentrating on creating top A styles.
Korg has been concentrating to add more controllabillity and tweakabillity
Needles to say that i'd love to have seen an arranger with all of these abbilities but the 4 big brothers in arranger land have not done that for me in the last 10 years ever since my PSR 9000/ GEM WX2 Combo.
Lionstracs is a good compromis that needs some/ a lot of tweaking when it comes straight out of the box but in the end the styles of Q-ranger can sound almost as good as an Audya. There will be even more controllabillity and tweakabillity as on Korg. IT has great solo sounds espescially with the right VST's installed, maybe not as easilly playable as Yamaha's SA2 sounds, but comming close. They are not cheap, but i think they offer a lot of buck for the money. While there is a lot of content created for Lionstracs my biggest worries are that styles programmed by semi-pro's like tastenpoint will never get the same level as styles programmed by Yamaha's and espescially Ketron's pros.
So for now my bet would be on Lionstracs. But somehow i hope that a new Korg arranger will bring us audio styles, Karma compatibillity, DNC2 sounds, even more controllabillty(free assignable knobs) and a special mode to operate VST's and Sequencers/programs on a remote computer.
If Korg can do this, they have a winner workstation replacing both M3 and PA2X pro.
I am not expecting anything TOTL arranger from Roland soon and Yamaha T4 and Ketron Audya have clearly missed my target...(tough both sound astonishing when compared to my PSR 9000).. they are not TOTL enough arranger.
