I made a software library for displaying piano music 7 years back, and recently ported it to the web (which is now easier than even ever).It displays sheet music as you play, and let's you take snapshots of specific chords, then keeps a running list of chords as keyboard visuals (instead of just displaying sheet music).Just a simple tool for songwriting/ figuring out songs by ear, or just understanding music key theory (which I'm admittedly a still a beginner at).

This is really cool!A small suggestion for improvement: the labels of the black keys currently don't match their function according to the key signature. For example, in F major the black key between A and B should be called Bb, not A#.

Not sure if you can help me here or someone reading this.I'm trying to find something to programatically make piano sounds (and record an mp3) based on 2 params midi note and velocity. I'm making a videogame and I need the mp3 piano notes.I got a free piano sample library, but the sounds start not always at the same microsecond, so I think I need to produce the samples by myself.

Interesting!However, while MIDI is 'working' (notes are highlighted when played), it doesn't produce any sound? But sound is produced when when clicking on the keyboard with the mouse...? Is there a setting somewhere to fix this?

Exactly what I always wanted. I can play naturally but don't know sheet music. Sometimes capturing what I play in notation helps to communicate it to other musicians I am hanging our with...

It requires some MIDI plugins, I was guessed it can convert from audio.

Great stuff, thanks. Very revealing, and the fact it recognises all of my midi devices (including the oxi one sequencer) means I can watch my arpeggios.

Do you mean it shows something you've already chosen, or it interprets and plots what you're making up in the moment?

Looks really neat on first glance, thanks for sharing.I'm working on some browser based piano learning software. Is this open source?
