Getting MIDI Data from Casio CT-S1 Keyboard

My iOS app using CoreMIDI is able to receive MIDI messages from various keyboards, but I have just received a note from a customer notifying me that my app does not appear to receive MIDI messages from his Casio CT-S1 keyboard. I am stymied on how to diagnose and fix this issue. Clearly there must be something amiss in my CoreMIDI integration. I thought perhaps someone else might have encountered a similar odd situation such as this.

If it helps, here is my CoreMIDI integration code. Thanks!

Regards,

Brad

Try my project in the BRossTools folder of the https://github.com/bradleyross/ObjectiveC-Examples GitHub Repository to see if you can get to the keyboard using MacOS. Documentation in https://bradleyross.github.io/ObjectiveC-Examples. I would be delighted to talk with you. I am finding the documentation extremely difficult to use.
