16 bars on a step sequencer is a crazy expectation, there's a reason almost nothing caters to that. Each step should count, a step sequencer is something that is programmed, usually for basslines and rhythms. Sounds like OP want a piano roll on all synths. Again, unrealistic. He should buy MPC Live and be set for every synth that will ever come out instead of experiencing perpetual disappointment. Not to mention the plethora of synths that have no sequencer at all - suddenly they are unlocked with the MPC's sequencer which is more than up to the task since it was actually built for this purpose.
