Hey everybody this is Sauraen. In the last year we've accomplished quite a lot on our
MIDIbox ASIDITY project [sorry guys, it's too funny, I'm not going to overwrite the defaults!]
%uh from a single break for running as Egypt to
a nearly complete case mostly completed hardware and partially completed
software
what I have to say today is a brief look at the case
a quick demo the front panel then it was in to
Boko 3 chip being prevail he C-seventeens course
let's take a quick look at the cases you can see it's mostly done but not quite
there is no no caps on the knobs a city features
35 digital outputs and 32 analog labs plus
16 analog toggle switches
top there Center the front panel is a four-color but merely to make checks and
then there's the two screens
bottom certainly right about buttons 3
LED displays
you have some fans on the site here and now looking at the rear paddle
you have 16 reports a in and I a doubt I
Master Audio out either a couple other audio outs and inns and then there's
16 ports which you see are not click to get this error for
external inputs and outputs for you sigit el-sissi
three USB ports one for each core a connector for an expandable
lede lighting solution and
power AC power in the switch so let's take a look inside
right now I only have connected all the front panel wiring
three processors this one is for the front panel
this one is for the sound chips and this one is for the sequencer the OP 03 board
and a MIDI interface board was the power supplies
if you're wearing that the city is going to fall off at this desk
don't be alarmed these power supplies are about 20 pounds total
and I if I if I push
on the synthesizer you can see that it's going to it sitting nicely with the
center of gravity
on the desk the front panel wiring
is pretty standard for many boxes there is a but you do.
DA out Indian modules single the airport here in a single T in board here
but there are a number of other day at work I
shift registers basically love life go to a few
two-and-a-half modules a along
this board which custom made as you can see the acidity logo there underneath
those
well supports I'm it the entire thing
not just the that the LED matrix but the entire
front panel whites are in a bind LED matrix
other eight rows controlled by aspect drivers which only does he think here
and coming from the first shift register
and the rest of them are that puts to
the columns %uh flights and that works the same way for buttons
I'm five shift registers one accord modules
and there's the LCD screens and their kinda buried
these analog circuits at the top the front panel the part that folds
upwards instead it downwards are the
the matter is for the sids feedback circuits I'm there's a bunch of analog
controls for them
at a cost which is like for from 3 said three-set since
winning diodes positive attention under for Justin cutoff voltage potentiometer
for Justin hardness and one for adjusting
the level of the external input said the final toggle switch
is to select whether this then there should be connected to the sids
input in which case it will them into the feedback
or whether it should be connected this is outlook which you can use the limiter
without using any feedback just read things does it affect
you may be wondering if this is many boxes City
where the sids I'm in the answer is that right here
these are the hour for
custom city back towards and doesn't design based on the set models with the
budget additional stuff I'm
the sick right the top so the size you here
a right along here from those two holes
there the other side but they get in the way
when I'm debugging Ochiltree module and besides the
they heard something about half working so far a.m. the
boards with the 85 eighties work basically
flawlessly and this one doesn't really work at all this one
is a partly working so you ask
but does any of this work are well yes it does
I'm it's not very exciting until
you have until I get all the course to communicate because then I can finally
have
control of sound from the for
can only control service by until then I
the front panel does this play nice little test animation
the Jos a city on the but merely the matrix and then
schools through tested *** each of the colors in the to the Elite is
I'm shows some things on the LED and LCD displays
it's better in the dark
as you can see the blue and red LED is in the in the matrix ur
basin break and the yellow and green LED's are kinda way P
that was our design mistake I we
met we bought happened to buy high brightness
reading I'll and blue LED is an the
yelling realities were just sort of ordinary greatness
but of course no self-respecting musician will buy or build
is hardware just because it looked cool as to sample to
and in with this respect the city is just as much a work in progress as it is
in every other respect I it works someone
I'm by there is still work to be done
so are you today the Tokyo fees and ***
from young I'll he sound card from 1985 I'm
is a standard part of the box for reform but
as far as I know never before control within of the C-seventeen
