Do not exclude the Ketron Products, SD5, SD1 Plus (soon to be replaced with the AUDYA), the older models X1, and also the older Solton (Previous name)...
Also, they are one of the 2 ONLY manufacturers that still make Arranger modules like the Xd3, SD3, Midjay and the older models X1m, MS40.
Consider this also, some of the Guitar players I know (Phoenix area), have retrofitted their guitars (as long you use steel strings) with a Midi pickup and that way they control their Ketron/Solton modules, basically I know of two pros, one is a lead guitarist, he plays the leads and embellishments(like the right hand), and his wife plays the chords (left hand), the other entertainer, she is a rhythm guitarist and singer, so, with the module and a pedal option they control real time the Intros, fills, variations, ends, etc.
A few entertainers in the Valley still use the MS50-60-100 besides the X1s, etc.
The advantage on this type of setup, is that you control it in Real time, and do not depend on restrictions on length of the songs ( if you need to cut it short or make it longer). Changes of key on the fly, changing the style of the same song and give a different feel, etc.
I think is good to keep all your options open, Hope it helps.
