It sounds like the firmware settings on your BB might pedal have changed (this will happen if you export your project from your BBM to your SD card. Could you check the MIDI settings on your BB pedal? You can change the settings on the Infinity using Pigtronix’s app.
– press Drum Set and Tempo to enter the settings menu
– scroll to and select Main Pedal
– scroll to and select MIDI Messages
– select MIDI-OUT
– scroll to and select Sync
– change to Disable and back out of the settings
On the tempo light not flashing, I think this is “normal” for the Infinity when the MIDI-OUT Sync has been disabled on your BeatBuddy.
