Analogue-sequencer

I own and Oberheim Xpander, and am stunned when I read accounts of it
being a tough synth to program, or that it is really awesome but the
interface is awkward.  The interface on the Oberheim Xpander is
absolutely wonderful - it has a huge amount of parameters and almost
all of them can be modulated, and you can literally get from anywhere
to anywhere in just two button presses.  Just two, and for most moves
just one!  So you can be adjusting envelope 5's decay and be on the
filter cutoff or vco tune in just one button press, or be on LFO 3's
frequency in two.  This means that after spending a couple days using
it you are super fast at moving around - it becomes like typing.. it
really does. So lots of parameters, but very easy to navigate.  

On the flip side I used to own a Waldorf Microwave XT and no matter
how long you used it, and despite the many, many knobs, the interface
I found difficult for two main reasons.  To really edit it, ie: add
any modulations etc you had to go via the menu system, and this meant
multiple button presses cycling through parameters and if you pressed
the button fast you risked scooting past the parameter you wanted to
edit and having to re-press the button many times to get back there. 
Always a different number of button presses to get there depending on
where you were starting from etc.  Modulations were in matrix format
which is not as intuitive as having the modulation attached to the
parameter like in the Xpander where you simply press the button under
the parameter and the up to five modulations sources for that
parameter instantly display and can be adjusted.. and etc..  So it was
powerful, and in time you could get a lot programmed, but because this
process was slower, you could never hope to really perform adjustments
of these more deep (is modulation routing really that deep?) aspects
of the synth because you could never be perfectly sure as to how
quickly you could get an adjustment or addition to the sound done.

How does the P3 with all its many parameters and capabilities rate in
this category?  Do people find they get really fast moving around in
it or is it always a very conscious step by step process to add and
adjust tracks.  

I really do appreciate you time and help on this.

thanks,
Greg.
