Needed - simple MidiBox for Breath Controller

[ShavenRaver]

I'd like to build (with my limited knowledge of this stuff TBH) the breath controller listed on this site by Matteo Bosi - http://www.ucapps.de/midibox_ext.html

But what I'd need after building that was a MidiBox to convert it to midi CC

errr... any ideas??? :)

OK, obviously I don't have the skills needed to design one from scratch, but if anyone knows of an exsisting project with a circuit diagram I can use I'd be able to build it

Nothing fancy AT ALL - it just takes a 0-5v input and throws out MIDI CC2

Any suggestions would be much appreciated

Thanks

1^st suggestion:

Midibox Plus! cheap,reliable and easy to build.

2^nd suggestion:

a single core module would do the job. just connect your breath controller to one of the analog inputs that are directly on the Core-PCB.

This will probably need a bit of programming.

I know you'll hate me for this, but I'm doing this to be a penny pincher really AND I don't have nearly enough knowledge to design anything even on this simple level

Something like this http://www.midisolutions.com/prodbth.htm would be ideal, but as I said I'm cheap, and for what it is i think this thing is expensive

Is there a circuit diagram for a single core module? It SOUNDS simple :P

The thing with sensors is, that they don't necessarily all produce 0-5Vs = 0..127 => trumpet sound low, trumpet sound high. so if you got a breath sensor that outputs 0.0 to 1.25 Vs you only get a very low mumble out of it. see the point?

That means, either you're going to construct a veeeeery complicated cicuit specialized for this sensor only and in the end you have a very tiny circuit that you may call "simple" (I don't), or you're using a cheap sensor-box, connect your sensor, calibrate it and you're done.

The ACSensorizer may run on a single Core, even without any HUI-Input. (Though an LCD is required to set up, but after setup you don't necesarily need an LCD). When you compare the costs for one core it should be one of the cheapest sensor-boxes available (~20 bucks).

A third option is to write your own application.

But again: simple != small != cheap

if you're fine with that specialized breath thingy, you might consider buying that. No soldering and no hassles there, but this kind of simplicity has it's price ;)

Well I think I've got the sensor part sorted - here is the link http://www.ucapps.de/midibox_ext.html

In that link are more links to the circuit diagrams...in fact here's 2 of 3 (the main breath controller bit - http://www.ucapps.de/midibox_ext/breath/Breath_controller_Schematics2.gif

So, I guess I'm looking for something that will take the 0-5V output of this thing and spit out CC2 0-127

I'm not certain what a single core is TBH but I'm definately looking for a something that is about as simple as the breath controller itself - which means that the information on how to build it is already there

I'm getting the distinct impression that it doesn't already exsist - except for 180 euros!!!
