hi @BN1701,

Please post your code you are testing to help us to help you 🙂

> that midi in events are named with forward slashes in 3.1 - “/midi/modal\_002\_48/25/1/note\_on”, but in 3.2 there are colons - “/midi:modal\_002\_48:25:1/note\_on”. Is this likely to be significant?

yep it’s normal. there is a change between these two versions.
