When I use Bluetooth-MIDI with Gesture.ThreeG and Gesture.SixG it seems the device is easy to throw 020 (out of memory) after a few impacts. This feels like something wrong in how memory is cleared perhaps?

It feels like this got worse, as this used to work. I can’t quantify as I didn’t keep record before of course, but are recent changes possibly causing this to occur (regressions)?

If you want to go back and try/compare a previous release you can specify the version in the url to get that: [https://makecode.microbit.org/v2.0.5](https://makecode.microbit.org/v2.0.5)

I’m not sure if there are release/deployment notes that specify exactly when releases go to beta and production…
