Since upgrading from 13 to 15.1, MIDI communication is unreliable (mostly nonexistent). Using Apple lightning camera USB adapter.

 and 3 keyboards including XWP1. After extensive talk with Apple support, it seems a Firmware update is required by each keyboard manufacturer to make the KeyStep communicate MIDI with iPad iOS 15.1.  (Apps tested include GarageBand, MidiWrench, ForScore.)

Anyone have a similar issue?

I didn't see an obvious post for this so I thought I'd post it. Here's a direct download PDF of the appendix, listing all the onboard default sounds:

As a new owner of a used XW, I'm grateful for this additional resource. Thanks in advance, AlenK!
