I know mine isn't an arranger, but my Roland synth has a "chord memory" which probably doesn't operate as they did on arrangers, but this is a very useful tool when recording, and greatly helps when I want to free both my hands up from chords so that I can focus on splits and solos.

My chord memory not only has tons of presets, but I can record user chord sets as well.
