Squeak, I think you can get enough drum /bass variation with Roland's top of the line arrangers[G1000,VA and G70] to handle Hip Hop..
Roland styles can easily be edited to have different pattern for every segment of a style if you need it that way..Also, you can change to any downbeat of the next measure ,to a new style.
Many drum kits are suitable without edits.
And you can EQ to handle any situation..[-12 to +12]..

The workstations are properly named..You have to work pretty long and hard to acheive results that still don't compare with an quality arranger..

I had a Triton Studio 76, and the only decent sequence tracks it could create were sparse Hip Hop type things...I couldn't [didn't want to] use it.

My Roland XP80 was better[I liked the sounds better than Korg]...but it couldn't do the job that my G1000 did..

Squeak, I know you have worked with the lower priced arrangers..Have you had the chance to work with SD1, G1000/VA/G70, Genesys etc...?

I think they are head and shoulders above the entry level keyboards that I am aware you owned in the past[PSR550, WK3500]..

If you are going to compare the workstations[non arranger workstations], we need to compare them to the Arranger workstations..
