After IOS 9, MD crashes when sending Program Change on Midi Channel 1

Question

Summary: MD crashes when sending Program Change over Midi Channel 1

---

Midi Designer 1.7.3 Build 17305 started crashing after I upgraded my IPAD to IOS 9.  I'm now at 9.2.1 This is a different issue, than has been previously identified.

I deleted the config.xml, but MD kept crashing.  While troubleshooting the instance of the crashes, I found that it was related to one device.  The device would accept Bank change commands, but whenever I sent a program change, the device would accept the change, and then MD would crash. Since MD was working fine with other midi devices, I decided to change the midi channel from 1 to 9, it now works perfectly every time.  I have been using MD for a couple of years, and these MD control panels have been in place for a long time.  I need all 16 channels to work, because I control my whole recording studio using MD.  I do not have any return communications going to the IPAD, it's outbound only.

I know it sounds strange, but it's happening, any assistance will be appreciated.  - Keith

We're very interested in this issue. Can you explain a bit about the one device that was problematic? And now... it's not problematic because you switched the channel? Ultimately we're going to want to recreate the crash here, but the issue is... figuring out what your device is sending back to get MD to crash. Thanks!

Wait, so you're saying that you have NO round-trip communications, so we could replicate this problem with JUST your layout? Can you reduce the issue down to just one or several controls on a blank layout, so we can test it in the lab? Thanks!
