pianoboi's Issues

Add snapshot functionality

Add a method of snapshotting notes/ chords.

Highlight notes that are sustained with pedal

If a note is released and the sustain pedal is active, maybe the key can be half-highlighted?

Add scale display

Add the scales to the display.

Tonal already includes all this information.

Node version

Hi! Which node.js version are you using? I am getting this error message:

Uncaught Error: The module '/Users/tomek.augustyn/Repos/pianoboi/node_modules/midi/build/Release/midi.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 67. This version of Node.js requires

No chord recognition, keys stays highlighted all the time and staves only shows max 2 chords

Great idea. I wanted to try it, but it doesn't behave as the picture say. I use latest Chrome browser. Windows 10. Novation Launchkey 61 midi keyboard.
Something is wrong regarding rendering what chords are pressed. There is no highlihting of chords. Also keys highlight stays on forever and it is not removed. On the staves you can only have 2 chords max.
Image with the problem1
Image with the problem2
These functions don't work properly:
highlightChords(majorChords); << doesn't highlight proper chord
highlightChords(minorChords); << doesn't highlight proper chord
highlightPianoKeys(keys); << It does highlighting and continuously does it afterwords, not removing previous highlights.

How can noobs install this?

Hi, how can I install this on Windows exactly? I don't know how to turn the code into an *.exe because I'm not a programmer and I don't understand GitHub.

Can you supply an pre-compiled installation file for Windows?

Midi Recognition

Wondering if there's any special trick to get the program to recognize incoming MIDI.
I can see from MIDI Studio that incoming MIDI is being recognized by my keyboard. But when running pianoboi, no input seems to be recognized.'

Running a Komplete Kontrol S49 Mk2. Pinoboi installed and started without issue. Running Node v12.9.1 from NVM.

Anything I'm missing or should try?

Thanks.

Keys and notes stick

It would be nice if note(s) gets cleared from the sheet after lifting the input key coming from the MIDI keyboard (also gets cleared from the piano roll)

Add midi input management

Need a UI to manage input devices.

Notes are duplicated in Bass and Treble Clef

Is this intended behavior?
Would it be feasible to merge the clefs so that they share middle C?
