Simple MIDI Wind Instrument
The idea is, to build a cheap wind instrument with a MIDI interface for the Atmega Controller. The program should be programmed in Bascom. This instrument should be simple and via a MIDI-USB interface can be plugged into a PC. Are there any interested parties, who would join? Initial trials are already there.Update 2/12/2013

The author seems to have abandonned this project, but we at Elektor (and we are not alone according to the number of contributions) still think that it would be an interesting project. So if someone would like to take it over, please let us know.

hpt, I noticed the dates on some of the posts here, and that this project seemed to be about a year-and-a-half old.
Do you still plan to 'manage' this project, or have you pretty much given up, or anything else? I'm not complaining to you, just wondering about the project's status and why there doesn't seem to be any active development going on--or I'm simply being blind to it, of course. :o)

By the way, my name is Kenneth Ogle. You all can call me Ken if you want.
This project is right in the direction I had decided to go as soon as I could finish getting my lab/electronics work area ready, which, for several reasons, may be a few weeks yet--but I certainly plan to contribute here as much as I am able.
I don't know of anything specific the project designer needs right now, so let me just throw in my 'two cents worth' about this device's performance.
Every MIDI wind instrument I find for sale in a music catalog is expensive--more expensive that seems justified (to me) by the job it needs to do. This could be, of course, because of my own ignorance regarding the difficulty of creating truly musical sounds by blowing into a tube and digitizing the signals thereby generated. But the goal of making it 'cheap' is a good one!
However, it's not worth it if this should result in an instrument that, in the end, isn't capable of performing (in the hands of a skilled musician) as a creative and truly musical instrument.
I'm afraid that if I say too much about high performance, someone will think I'm reaching for an unreasonably high standard, but if I don't, that . . . well, in the end, it may not be what it could have been. Something like that.
If that sounds patronizing or condescending, PLEASE accept my apologies, because that was hardly my intention. Maybe it's just that I haven't done anything like this before.

I actually did this some years ago and i should be able to find the hardware. I build a midi flute. 10 keys for fingers and a on/off switch that could be controlled by the lips to simulate 'the blow' it sends out midi signal using a midi DIN connection.
I never finished the part to detect the airflow to control volume, however i will upload the hardware schematics and firmware later...
I am even more interested in standalone midi synthesiser that can be used by this flute or wind instrument so that i don't have to drag my keyboard along...
The VS1053 chip from vlsi might be a good solution for that.
28-3-2013, I uploaded a schematic and some raw assembly code...i did this long time ago so i cant remember all the details...but it might give people some ideas on how to do it.
I also did a version with a tiny avr controller for which i have firware code in C ( codevision) but i misplaced the schematic. As soon as I recover it, I will upload both the schematic and the code.
assembly code ....not finished! no support! (80kb)

Instead of using switches to select the tone it could be possible to use a gyroscope or Mems device which measures movement and angle.

the project already gives an answer to a question not defined.
Maybe the answer is AVR but why? Maybe the answer is Bascom, but why?
I would be really interested if the project could add a synth from these people : http://www.dream.fr/devices.html
For sensor you could use : http://nl.farnell.com/freescale-semiconductor/mpx5010dp/ic-pressure-sensor/dp/1555605
This guy already made a flute with it http://vimeo.com/2672978
Hope this gives some direction to other people.

I would be interested in this project too. I think the method of detection of the breath would be crucial so I am wondering whether it is proposed to develop a transducer or to use an existing breath controller? I also think it would be easier to start with a hardware MIDI output in order to avoid issues with USB MIDI drivers. Hardware MIDI is easy to do with a UART. This could be a standalone device if there was a MIDI input which would merge the input with the breath control in order to avoid the need for an external MIDI merger (although the MIDI merge function is often provided by the DAW these days).

Sounds like a nice and fun project, but some more details of what's already there would be nice.

What exactly are you looking for?

You should add this (in English if possible) to your project description, otherwise people may not find it.
So you are looking for help with the wind part of the instrument. Have you tried the heated NTC technique to detect blowing? It was used in this project: http://www.elektor.com/magazines/2011/december/electronic-led-candle.1992164.lynkx
