MOTM

a) I can always make it 3U wide but it will be more $$ (say from $299 to 
$359, still less than others out there).

b) I can make it dual with more features. So maybe it's a dual (2U) versus 
quad  (3U) issue. One advantage of the 3U wide is I can use the same 
encoder/display scheme as the Cloud Expander (6 programmable parameters at 
once in the display).

c) I understand that people change the scale via CV all the time. But, and 
this is an important thing to consider, is it changed *precisely*? Or do 
people "just want it to change" every so often, and not care *exactly* what 
scale is used, just to it's "not the last one".

Because this implies 2 things:

1 - the scales are in the 'correct' order
2 - you are somehow feeding a "target voltage" in there and picking out the 
*exact* scale of interest

What I will bet is that people just want some sort of *change*, that moving 
*specifically* from ScaleA to ScaleB is not the intent, but rather "boy this 
sounds neat if I have change to a different scal ever so often". The reason 
I bring this up is how the HW/SW is implemented. If you are implying that "I 
like to *sweep* through" a certain MiniWave bank/set of scales, saw with a 
sawtooth LFO or whatnot, that is very different than "just hop over to 
something different".

The other implication is being able to have a "scale librarian" (why I 
prefer the USB model) because then you can re-order the scales/banks around 
to your liking. You *need this* in order to 'sweep through' a scale set in a 
given sequence. Otherwise you are at the mercy of how the scale ordering is 
done at the outset.

Many people like this MiniWave feature, but I suspect they just "throw" CVs 
at it an see what comes out :)
