Chord gets buggy over time

[pikurasa]

Description

When using the chord block, it starts performing pitches outside the key over time.

This is what I've observed:

• The first performance seems to be accurate every time.
• Over time, the chord block performs notes that aren't specified.
• I suspect it may be picking up something residual from a combination of 1) set key/mode 2) the chords that take us outside of a scale (e.g. major, minor, etc). That being said, my ear is telling me (listening to the video copied below) that the second performance seems to have doubled unisons of every pitch of the chord for the first chord (even though it doesn't have any notes that are outside the chord).

Expected Behavior

The subsequent performances of the chord block should be the same as its first performance, which is correct.

Console log Errors:

I don't see anything special in the logs.

I cannot reproduce this. Can you share logs so I can see the notes being passed to the synth?

I don't know precisely what triggers this, and I'm really having a hard time reproducing it at the moment, but I experienced this when I was working on Now and Then, and my student ran into it (on https://musicblocks.sugarlabs.org/) when working on the Flamenco Rhythm project.

I'll keep a lookout for it, and try to capture the logs if/when I spot it again.

could the issue be related to your device?

I cannot seem to reproduce this, anything to work on?
