Yes, all up to date.
I had not played in a while. I was having some sound drop out issues previously but traced that to a cracked power supply on my Whammy pedal and fixed that. I reconfigured my pedalboard a little, mostly just trying to add the Aeros Looper so I could go with hardware looping, thinking it might be more reliable than what I have achieved with Loopy HD, but long story short, the Aeros looper does not have enough MIDI control available at this time, and I misread their intent to get this up and working soon. So anyway, I am back to the use of LoopyHD and my RME Babyface.
I am FAIRLY certain I did not have the MIDI dropouts when I got my board going again UNTIL I did the updates, which included updates to Bandhelper, iOs, and also to Audiobus. I do not have any MIDI channeling going in Audiobus...only use it for audio routing settings, so that should not be it.
I have looked through settings and tried various things to see if they have any effect. You can comment on them...some I don't understand their role in my setup:
1) Tried with "Play First 2 Recordings Together" both on and off. Seems to work either way, so right now I have it on, but seems to not be needed as MIDI files runs along with the audio file, so not considered a "recording" by Bandhelper anyway I guess
2) I removed the Tempo output channel. I had it set to Babyface Channel 3...are those MIDI channels showing up? It does not seem to do anything that I can see, and I get tempo info sent from Bandhelper by having MIDI Clock on. Looking at it now, with the RME Babyface unconnected, it gives me options of Speaker 1, Speaker 2 whereas before was Babyface Channels 1-12...so this appears to be selecting output for Bandhelper's tempo sound, not MIDI info. Anyway, I have deselected it.
3) Have tried with "Low Latency Recordings" and "Low Latency Tempos" on and off. Does not seem to matter. I left them on for now, though not clear to me what that does. I have set my "Delay Audio" to 0.05 sec, which seems to provide the best accuracy for my loop recordings.
4) I do not have a MIDI Soundfont file. I am not sure what this is or whether it is relevant to my set-up. I go to Recordings and attach a MIDI File to each backing track and the MIDI File has always run pretty reliably until now, where it variably seems to stop working. In addition to the MIDI file stopping, basically all MIDI shuts down: when I pick a new song, no MIDI Presets are communicated to my gear until I restart Bandhelper.
5) Send MIDI Beat clock is ON and sent to all Ports. I did learn months ago that I could have MIDI conflicts as MIDI clock would go to Bandhelper to my gear, but also through Loopy HD and to the gear, giving me crazy tempo results on my pedalboard gear. That was fixed by having no MIDI flow out of Loopy HD. I think the clock was getting roughly doubled.
6) Start MIDI on Auto-mute is OFF, and Auto-Mute instead of Auto-Stop is OFF. Not sure what these do anyway.
7) Send Custom MIDI is OFF
The only other difference from when this was last working well, I did have the RME Babyface set up with both MIDI Out and MIDI In connected to my other gear. Since I am not currently controlling anything on the iPad with my pedalboard gear, I saw no need to connect a cable to MIDI In. I will try reconnecting that and see what happens, but not sure if that would somehow affect MIDI stability. I have MIDI Thru in Bandhelper OFF, since MIDI flow in my setup is all FROM Bandhelper...nothing going to or thru it.
