[BRX]

Happened again. Same location and situation. I can't provide many pointers, but it happened again when I connected my master tablet with a slave tablet (both iPads automatically connected from the last session, the one when it happened before). They have the same chord book on them and I was choosing the songs on my tablet and "driving" the slave for the bassist. Instead of 22 letters there were only 10  showing up.

When I restarted MSP only on the master at home all the letters were present again so the master-slave-bluetooth-connection seems to be the culprit for whatever reason.
