Hello,
I would like to make an audio to midi converter for a Turkish Qanun:
What I would like to have your opinion about is, is it doable using teensy and which method should I work on?
FFT Method:
Trying to detect all notes (polyphonic) using a single input and a single teensy, relying on the computational capabilities of the chip and the software to be coded.
Simple mics:
Small mics under every string, connected to the teensy via shift registers. Basically, the following information is enough because there we do not have frets:
Optic Method:
I wouldn't try this
What have I done so far?
I am a designer/developer/hacker, I usually work on web based projects. I also play the guitar and produce music using DAW's, I know about midi and music. I have little experience about electronics but am willing to learn!
Any help is appreciated, thanks.

I would like to make an audio to midi converter for a Turkish Qanun:
- This is a 25+ nylon stringed instrument.
- The traditional instrument has string groups formed of three, this one will have only one string per group.
- Not a fretted instrument, similar to the harp. All strings can produce one note only.
What I would like to have your opinion about is, is it doable using teensy and which method should I work on?

- Polyphony?
Simple mics:
Small mics under every string, connected to the teensy via shift registers. Basically, the following information is enough because there we do not have frets:
- Was this individual string plucked?
- Level (Velocity in musical terms)
Optic Method:

What have I done so far?
- I found this nice free software called AudioXplorer for reading analyzing audio, it is discontinued but provides real time reading.
- Using the tone-input tutorial on Adafruit website. (Click here for the code). I did get it working for a single note, now when I whistle A5, the teensy led blinks But the example here uses some low level stuff which I could not understand (<arm_math.h>) I can not debug in any way, can't print anything on serial monitor, also I don't have an oscillator...
- Gone through Paul Stoffregen's Audio Analysis Examples but I could not understand how these examples should work without the audio input component for teensy. I only have the Electret Microphone Amplifier - MAX4466 with Adjustable Gain.
