Eliminate the keyboard altogether since your already creating tracks on the computer with VST, DAW, BIAB, etc,.....which with the right VST's can create the Best sounding Pianos, instruments, etc, and just sing to your backing tracks using a laptop etc, save money too no need for an arranger,...a Genos is not needed to do this at $5000.00+. Good luck.
I still play a piano type of sound with the track... so I still need a keyboard. Also, I need to keep everything in front of me. As I’m selecting the song, I talk to the crowd or tell stories. At church, I talk while transitioning from one song to the next. While I am without a “gigging” keyboard, I am using an iPad and my Roland FP-50. The output is ok in the iPad but there is no parlance control.
We all know you should be able to get the Genos for below the $5000 mark. Plus, selling the Pa4X, Motif XF, and my Roland VP-770 gives me enough funds to have choices.
Mac laptop... audio interface... keyboard to hook into Mainstage... $3300. For $700 more... I can get a Genos and get the arranger functions as a bonus.
