Hi i need to design a sistem to control 40 diferents audio files and playback in a stereo sistem. I was thinking to use puredata and arduino, load the 40 audios in a pd patch and use 40 switches and resistors into some arduino inputs to trigger and playback any of the 40 audios in pd. Every switch will be conected to a diferent resistor to generate diferents voltages then arduino inputs can diferenciate witch audio to playback. Also i need to power on a led any time a specific audio is been playback. The 40 audios will not be playback simultanusly, but probably al least 15 or 20 could be.
Anybody knows about a similar proyect? can i use analog input to control various samples or its not good idea? multiplexors? do i need to use an arduino mega or its not necesary?can i power 15-20 led simultaneously? the best way to do this system stable for long long time?
Thanks

The analog input method is similar to the resistor ladder that analog synthesizer keyboards used. Arduino analog inputs can differentiate 1024 levels but the values of resistors are usually 5%, but 40 levels should be easy. The best way to do LEDs is with shift registers. That way you can use just 3 pins on the Arduino to control as many LEDs as you like. For LEDs use parallel-output shift registers, like the 74HC164. Also the input could be done with parallel-load shift registers (for example the 74HC165), but the resistor method is cheaper. It should be quite stable over time.

Thanks for answer
Martin: I am researching about shift registers, but if the idea is to use puredata to control audio playbacks, thats means that i need to control shift registers with pd? because the arduino will be flashed with pd firmdata and will be imposible to upload code to control shift registers, is that posible or i am thinking wrong? Thanks again
Best!

You could buy an Arduino Mega, that has at least 40 inputs. Then you
don't need a shift register, just the Arduino Mega with Firmata.
That's a simpler solution, IMHO.

It's certainly possible to make a Pd patch that controls shift registers through firmata. It's also possible to program the Arduino to do that and send the switch numbers to a Pd patch that has a [comport] in it.

I think people have done some shift register+firmata things, but
nothing got integrated into StandardFirmata/ Here's an example:

Hi guys
I was researching about arduino mega and pd firmata and i found a post where they say that its not posible to use all digital output and analog inputs of arduino mega. http://arduino.cc/forum/index.php?topic=62256.0
I gona buy arduino mega this week, but i need all inputs-output working for my proyect. Do you know something about this incompatibility??
thanks
