Bools: Start and Length Wrap display 1

(for anyone stumbling upon this, the thing above is the beginning
of a GUI thing to show active steps on a 16x step row, with variable
start and length, where the led display will eventually show the
block of active steps, and wrap around at the front of the row when
total length exceeds 16)
oh, so i need a comparator + switch now..

here's the old version:

seq start position and length display with wrap

comparing this approach to KlangManipulation's method with
a DH Patch Array 'thru' daisychain..still have to figure that
one with a rebuild in 1.0x ..
>it only allows nudging one step each way at a time
>requires transport run to be on.

this one can be operated continuously with faders/knobs for
start and end - how it ends up operating: call length 'end'
and use start to shift <L/R>

GUI Int could be good for this since #2 relies on 0-15 count.
then find a way to combine with something like #1 for logic
state of leds.

why would you do this? the LEDs aren't just the display, they
are bools thru lines, and part of the sequencer's gate logic.
it seems like a lot of cables but it's really simple and direct
once it runs, running on limited value range: 0/1
this is just a stage of something that is in bits, it could be done
the old way but i want to do it all GUI-side.

RH LogicGates2 is interesting because it is the bool in/bool out
version (the other one is GUI Int, maybe worth another look*thinks*)
and is a (hehe) 'versatile' basic gate: it can do all the basic gates:
AND/OR/NOT/NAND/NOR/XOR/XNOR(not in that order) eg: 6 gate functions ,
operated by GUIList. -perfect, you'd think, but i've found a way to stop
it selecting atm, i think it is a 'bring module to front' situation: it
loads defaulting to first list item -

not just that: RH LG2 also offers left and right pins for:
GUIFloat/GUI Int/GUI Text , as well as both-sides output for GUIBools
(inputs are left side, as are inputs to the DH logic sems.

<-digression-> in fact i find the original way of working with GUIbools/float/
text/int/list perfectly logical - regarding direction flow of signal/data - :
once you get your head round it, it becomes second nature. hence my
unreasonable fear of 1.1+. i'd say, re: SE development, get it working under
the bonnet, racing machine, and then take it back to basics, offering classic
style and the latest presentation. just my personal perception. resources and
time needed etc. but from the occasional 1.2 notices from Jeff, you get the
feeling some progress is being made. the question of you can have either this
or that seems to have been sidelined because of demand for both: 64bit and..
ah, no: it was about VST3 support. the other request has been Mac export.
so whatever VST3 is...
would you really worry about that as a SE user, when you can find a way to
connect most things anyway?<-digression over->)
