Playback for "Hyperscore" example project is broken

[pikurasa]

Description

Expected Behavior

Our "Hyperscore" super-example can be found here: https://sugarlabs.github.io/musicblocks/index.html?id=1523896294964170&run=True&run=True

It paints the music just fine, but when you press the play button to generate a stack of notes for what you played, it creates rests, throws a few errors, and even seems to get a start block stuck inside a note. (See images below.)

How to Reproduce

Open https://sugarlabs.github.io/musicblocks/index.html?id=1523896294964170&run=True&run=True, paint a bit, and press the play button at the top.

Note blocks will generate, but some will generate incorrectly.

Hi @pikurasa
I am having some issues reproducing this issue.

The URL you provide doesn't seem to give an issue. Is there something I am not saying. Would really appreciate anybody's assistance on this one.

The Planet server is down at the moment.

In the meantime, I'm trying to see if we can get you a file you can open while we're working that out.

Sorry. I should have added this project to the examples folder, but I never did. I don't have a local copy.

I looked even deeper onto some backups I have of old files, and I found this (from 4/16/2018):

Remix of Hyperscore tonal.zip

It appears to be a remix of one of your versions, @walterbender

I'll make a PR. The file does seem to work...

[pikurasa]

Before making a PR, I'm trying to clean it up. This is it's current state. The logic could be clearer, but it works ok right now.

@suryaanshah if you like, you're welcome to start from the file pasted above and improve it.

You should reference https://github.com/sugarlabs/musicblocks/tree/master/guide/#37-interactions as a guide as you work to get it working. If you like, you could start from the file above and rearrange the blocks to be as they are in the image. Then, you can see if you can reproduce the issue.
