hi there
i have come across with a title which i am interested in
where after a short piece is played the PC will show which keys has been played
however,
can anyone tell me
can arduino do convertion of piano letters ( C D E F G ) to piano notes?
Sure. I posted a sketch recently where I created up to 13 piano notes in response to button presses. Code had the frequencies used in it.
Search for "piano tones" and look for a posting I made.
You could adapt that read serial data and play notes instead of reacting to button presses.
I don't understand exactly what you are trying to do, but a [u]MIDI[/u] keyboard with MIDI software is probably the best solution.
With MIDI, you are just capturing (and/or saving/sending) the keypresses or the notes, so there is very little processing required and it's very efficient. With some additional hardware, the Arduino can handle that if you don't want to use your computer.
There is audio-to-MIDI software that can take a signal from a microphone and determine the notes & timing and create a MIDI file, but I'm not sure how well that works with chords. That kind of processing (especially analyzing chords) probably takes more processing power than the Arduino.
i would say that
i wil like to have a simple piano with one octave
and can record the pieces played and show on the PC screen which key e.g C, D, E etc. has been played
and
also show the piano notes ( 5line notes) too...
Sorry but are making no sense and you are not answering the questions asked of you.
what is the output of this piano?
Is it audio MIDI or something else?
