This is really a multi-purpose box! :-)

this is my new midibox 32E with 16 analog pots, 16 encoders, some buttons

(perhaps too few!!), and only one ledring for all the encoders.

this box replaces my 4 years old midibox 16, that was inserted in a paper

shoes box!

i also integrated a joystick, which can be selected to operate instead of

two pots with a switch.

i tried to adapt an old PC joystick, but unfortunately it didnt worked. i

built a gain circuit, because the pots used in the joystick are not used in

their full range, so the voltage output had to be adapted to the 0-5V

required by the ain module. but this introdueced lot of noise, and the

extenision is basically unusable.

but i'm waiting to get a 10K joystick, and then i will replace this with a

better one!!

moreover, i integrated also my old breath controller unit (fig.11). now the

board dedicated to the breath controller is inside the box, and only the

breath unit needs to be connected to the box to be used. as with the

joystick, the brath controller can be selected by a switch to be used

instead of a pot.

the LCD is backlit, but i decided to disconnect the backlight because it

sucks a lot of current and the voltage regulator become HOT!! not a

problem, anyway...

the only thing that makes me sad is the impossibility of making analogpots

behave in the "snap" mode by default... so that everything would become

more usable...

the case is built by myself (two days of working!) in wood and then

painted. the upper panel is a plexyglass panel (cheap and, most important,

easy warkable). i decided to paint it, even if i thought to let it in the

original "transparent" look as my sid.

the case is built with the possibility to mount a music stand: in the fig.7

you see, near the plug for the breath controller, two guides into which

insert the stand (obviously these are also on the other side!), like show

in fig. 9 and 10

(the "black look" doesn show it vey well because of the contrast....)

the basic use of this box will be as midi controller for vst and FX (no

logic control emulation and so on...).

last thing: the power supply of the unit comes directly from my

masterkeyboard (the one you see below the MB). i soldered two wires to the

keyboard power supply and let them exit form the rear. then, they arrive to

a plug for the midibox. easy and practical: when i turn on the

masterkeyboard, the MB is turned on automatically! :-) (fig.8)

total cost: i think we are around 100-120 euro, even if the parts were

bought in different time ando so i cannot remember precisely.

since the midi input is used by the keyobard (with merger on), in order to

connect the PC ouput to the MB, i plan to build also the midibox merger, so

that i can "mix" the midisignal coming from both the keyboard and from the

PC (for MIDI feedback...)

the worse part is that all my PC Midi connections are used (both in/outs...

BIG setup here!!! :-D), and so the only solution to deliver midi data from

the PC to the MB that i have is to build also a midi thrubox...

see you and thanks for all!

great one , the big joystick is terrific! did you find a way to use the switch on the top of it?

i no more find the post where TK explain how to use only one ledring, can you put this info here? (or a link)?

unfortunately, that joystick will be replaced... even if the look is marvelous! ;-)

but perhaps i will take the pots from the 10K joystick that i'm waiting and will mount them onto this one...

the top button was not connected, even if in principle i could take the wires and solder them in a AIN input... but i didnt fell that that button was usable, so i didnt connect it!
