Well, a MODX ain’t no arranger! But an SX900 has eight freely assignable inserts, and a Genos has 28!
So yes, Korg got some catching up to do.
Not even a Nautilus is an arranger (maybe a submarine?). So, although a Genos can only use a theoretical maximum of 12 inserts in arranger mode (1 for each 8 acmp parts + 1 for each 4 right hand parts), the current Korg arrangers have even more to catch up!
With our software, on the same Yamaha hardware, you can use more Inserts, up to 16, and even 2 per part (16x1 or 8x2). A thing that builtin Yamaha firmware cannot do.
