Build a MIDI controller ??? (Read 23080 times)

Hi,

I'm a newbie here!

I plan to build a MIDI controller.

I watched around midibox.org stuff, but I guess arduino/wiring are more open, more directed to the future (OSC, etc etc)

here is a little sketch: ...

I need a lot of LEDs, a lot of button.

Could Wiring board natively support that?
Any ideas about making that with arduino? I mean, Do I have to use Processing (only) between hardare and my MIDI Application ? or can I use max/msp ? or even, none soft interface (C/C++ embedded?!) ??

Any informations appreciated Smiley

I would choose Wiring above arduino,
since wiring has way more pins and speed.
how many switches? and how many leds(RBG leds?)?

56 LEDS (rgb) + about 66 Buttons..

then you'll definetly need 2/2+ wiring boards(or 4/5+ arduino Tongue).
Did you take a look at a led driver? just to scale down the I/O's needed for the leds

They all need to be controlled individually?

with 2/2+, you mean "at least 2 boards ?

I didn't take a look at a led driver ; I'll look for infos about that
yes, all need to be control individually and via MIDI message (CC or NoteON/Off)
but this part can be software part, if I understood right..

Is Wiring interfaceable directly with MAX/msp? or Does it require Processing/Wiring environment?

well, if you are experienced with electronics and with programming, you could do it with 1, but it's so much easier to do with 2. Though with the led drivers and a smart electronics thing you could do it with one.

I hope someone reacts soon, more people, more ideas, quicker solutions

Hello,
         Hey I'm not sure how you would do it but you could wire the LEDs a a matrix.  The programing would be a little tricky.   This my be what Titus was thinking of.  It would take you 56 out puts and turn them into 3.  You could do the same thing with the buttoms.  They do it with key boards.

     Good Luck and if I run across something I'll post it.

that was what i was thinking of, you could even use 3 PWM as outputs then, easier for the code.

I'll give it a thought and a dream tonight,

Hey,
         Are you going to use three color LEDs that would be 168 outputs to handle it straight to the board.  If you use three matrixes you will only use 9 out puts.  again the programing could be quite tricky.

check out the Wiring Hello matrix example...

http://www.wiring.org.co/learning/examples/hello_matrix.html

I hope this helps.

RGB colors LEDS would be nice

I'd like to build my own matrix, not utilize an already existing matrix
because I have to build a gear with precise size..


What could be the interfacing:
-gear<--usb-->{wiring environement}<--MIDI inter application-->{My MIDI application}
-gear<--MIDI-->{wiring environement}<--MIDI inter application-->{My MIDI application}

can I build an architecture without wiring environement ?? (I mean, with embedded code)

             That was the idea I was talking about.  a matrixis a way of wiring up a group of devices.  You would have to wire them yourself.  You could wire the LEDs in three matrixs and the switches as well.  Then youwould use encoder/decoder chips to send the signals to nd from the wiring board.

Yes you can interface Wiring with MAX/msp directly.

ok
thanks a lot(again)

barragan, can I send directly midi from/to maxmsp to/from wiring board?
I guess: yes!

I hesitate between wiring and a midibox stuff... more specialized, but less open (obviously!)

did someone already do that? I mean making midi stuff with wiring

I really hesitate with a midibox...
