Just to follow up on what Jerry said, the Genesys Pro (61 keys with out speakers), is not just an arranger but has a very powerful sequencer.
There is also an extensive sound editing capability. It has a quick sound edit where you can change filters resonance and so on. There is also another sound editing capability that goes in to the details on sound editing.
It is perhaps the easiest and the most intuitive keyboard to use.
Once you know what you want, the manual would direct you as to accomplishing your task.
You can create your drum tracks in the styles section so it can function as a drum machine.
When you are finished tweaking your sounds, it has 256 places you can save them to (call presets) and over 1000 memories.
It also has a sampler.
It may be on the pricey side but it is by far the keyboard/synthwork station/ arranger where you get the most for your money. There is also a module (genesys xp) that should be coming out soon so maybe you can wait for that.
