I sense you are a piano player - as I am - so what you probably want to use is the full keyboard set up. This works great for piano, electric piano sounds, and best with AI full keyboard setting. The accompaniment will be driven automatically by your playing across the whole keyboard, rather than split into lh/rh sections.
Chris is right about the connector, this is important, but the Maudio 88 MK3 controller fits the bill well, as do some others. The more expensive hammer simulated controllers, get to be heavy and expensive, and in order to justify the additional cost usually throw in many more complicated features you may not need. If you are a very advanced synth player, who loves all these features, this might be different, but piano players like my self and David Read on this forum find the semi weighted sound perfectly fine - and usually much better than the hundreds of bad pianos we frequently had to play in the past.
As a comparison, the typical 88key pro hammer simulated keyboard will weighs around 40 lbs and cost about $800. The semi weighted MK3 costs about $250 and weighs 13 lbs.
