Right now with the manual settings there's always at least one note in each clef. It should be possible to match the adjustable difficulty which starts with only a single note at a time in the treble clef.

Using sheetmusictutor.com local data is saved between page visits. Over a longer period of time the amount of data continues to grow. At over 6000 notes played the webapp becomes sluggish and the time from playing a note until it being recognized increases to a point where it's not very usable.

Right now Chrome finds five MIDI devices connected to my computer and it can be annoying to figure out which is the one I'm looking for. If instead the MIDI device names were used this would be much more intuitive.

My OS has chosen the piano as 2nd MIDI input device next to some other one for whatever reason.

So allowing to select the MIDI input device would be nice.

Hi,

Sweet app! Thank you for this :)

Would you accept a key select drop-down menu in the UI? If the user selected a key, the generator would only produce notes in that key. The idea is that training can be boring, so it would be fun to play your favorite music in the background and "play along" in the trainer in the key of the background music so that the notes played are a reasonable match for it.

In my PR I added a "How to contribute" section which just makes it easier to see the compilation info. Some more documentation could make contributing a bit easier.

For example, right now I see there's CI setup and it appears to be doing some kind of linting. It'd be nice if how to run this linter was documented.

First of all, this is an awesome project and I hope that it is not abandoned yet.

I noticed that it helped me a lot, but I miss generation of flat/sharp notes.
Also, I would like an option to change the scale.

So I suggest to add:

• Possibility to change the base scale
• Generation of notes outside of the current scale (with lower probability)

It appears that all note stems on the treble clef staff are pointing up. The following algorithm can be applied for the treble clef staff:

1. If note is below line three (3), stem direction is up.
2. If note is on or above line three (3), stem direction is down.

The following is an excerpt from How To Read Sheet Music: A Step-by-Step Guide:

The note stem is a thin line that extends either up or down from the note head. The line extends from the right if pointing upward or from the left if pointing downward. The direction of the line doesn’t affect how you play the note but serves to make the notes easier to read while allowing them to fit neatly on the staff. As a rule, any notes at or above the “B” line on the staff have downward pointing stems, those notes below the “B” line have upward pointing stems.

e.g. C 7, C m7, C maj7, C m#7, C dim7, C half dim

It would be nice to have an option, to reset the level when using automatic difficulty.
Currently when doing too many mistakes, the level will reset to 1 but go right back to where you've been before, e.g. 8.

If someone wants to start over, there is currently no option to do so (aside from deleting the cache, I guess?)

Also the automatic difficulty could be done in a more sophisticated way, going down only one level after too many mistakes, instead of jumping between levels 1 and MAX_REACHED.

Great project, btw.!

As it currently is (judging from the version at sheetmusictutor.com), there's no way to limit the range of notes that can be displayed. This isn't a problem if you're using a full keyboard, but if you're working with something much smaller like a little 25 keyboard you'll quickly run into notes you can't play.

Would you accept a PR to add two new settings for a lowest key and highest key? I'm thinking to start they could be drop down lists, but having additional MIDI learn buttons would be even better.

First thanks a lot for creating this amazing repository! I was about to create something like this for my Jazz chord practice before I found it! There are however two features I am currently missing compared to the version I had in mind:

• Jazz chord notation (symbol notation) support.
• Multi bar support.

Jazz chord notation (symbol notation):

With this I mean the notation that is often used in lead sheets (see this document):

Multi bar support

The ability to see more bars in advance when training (For example one line of 4 bars). I think by doing this both sight-reading and eye scanning would be trained.

I'm happy to develop these features if there is support from the community.

Hi Philipp,
I really love what you've done here with this app. My only suggestion would be to add a "minimal view" option. For example, when practicing I find the background image and side widgets a bit distracting. I'd love to have the option to see just the score and a white background.
Thanks,
Ben

I tried setting up this project locally but unfortunately, the website is not displaying. After following the instructions in the README.md I get the following error when running npm start:

Uncaught SyntaxError: Cannot use import statement outside a module

Does anybody know with which npm versions this project is working?

Current system information

OS: Ubuntu 18.03
node version: 8.17.0 and 14.13.0
npm version: 6.13.4 and 6.14.8
firefox version: 81.0
chrome version: 85.0.4183.121

Given a user who takes longer than 30 seconds rather often, a substantial chunk of valid data is discarded.

e.g. I've been studying piano for <60 hours (~45-55) and these (because they're outside the normal introductory playing range etc.) take anywhere from 12-40 seconds
