I have had my Korg pa1x for close to 13 years . It's interesting the way I have changed the way i have used it over the years . I used to use the style element 40 percent of the time (using out the box and custom made styles ) sequencer 30 percent and straight keys 30percent . Never used the sampler and still don't . I did tweak and modify sounds and effects a fair bit to replicate the sounds on the cds or you tube clips of songs I was asked to teach the choir .
Back then I was choir musical director and so at rehearsals ,having an "instant band " always on time , always in sync and flexible enough to accommodate a wide range of music in any key was really a great advantage .
Now many years on I have slowed down my choir work and now only arrange and compose and perform . I use the sequencer 40 percent of the time , and play straight keys ( on my stage piano and Korg arranger ) 40 percent of the time and use styles for quick sketch pad work the remaining 20 percent .
But the amazing by thing is how comprehensive and adaptable the arranger keyboard has been for any and every environment I have found myself in . Whether that is in the studio recording , performing live , or just doodling with musical ideas . The only reason I can see the market dying is that people like me don't buy arrangers very frequently . I certainly hope the market continues . I have benefited from it greatly .
